Garage door insulation in simple and affordable ways. We insulate the garage door from the inside - proven ways

The condition of the vehicle largely depends on the temperature in the garage, but, above all, its rubber-technical elements. Moreover, the warmer it is in the room, the more comfortable it will be to use the car inside in winter period. Finally, the temperature here also affects the microclimatic conditions in the basement (if any) under the garage. And in order to keep the heat inside the garage, it is necessary to carefully insulate it. So, today we will talk about how to insulate garage doors with your own hands.

Do I need to insulate the gate at all?

To find out if the gate really needs to be insulated, you need to understand one extremely important thing for yourself. important point. So, even without taking into account the winter cold, the usual thermal fluctuation in the warm and daylight hours can lead to the formation of condensate in the garage. Permanently elevated level humidity has a negative effect not only on the condition of the object, but also on the body of the vehicle: metal surfaces become rusty, electrical wiring begins to rot, and mold or fungus appears in the corners of the garage.

As soon as the condensate freezes, the finishing material will begin to crack due to moisture. But there is great news - it is quite difficult to solve such a seemingly serious problem! It is only necessary to choose the insulating material, and then personally carry out the appropriate measures to insulate the gates and doors. As soon as the work is completed, the temperature in the garage will not fall below the 5 C mark. Let's find out how to do this.

What generally can be done? Getting ready for work

There are several options at once: for example, you can simply purchase and install modern high-quality garage doors that are already equipped with insulating material, or you can do the thermal insulation of existing doors on your own, which, of course, will cost much less. A lot of time for this will not be required, as well as special skills in construction.

Note! The garage doors themselves are thin, so they are unable to reliably protect from the cold in winter. Heat metal garage generally unreasonable, since the only thing you will achieve in this case is the formation of condensate on the walls.

It is also worth noting that it is better to insulate the gate from the outside, although this is often impossible. At internal insulation condensate will appear in those areas where the insulation is in contact with metal surfaces, for this reason, all surfaces should be protected with an anti-corrosion agent, and the heat insulator itself should be fixed as tightly as possible in order to avoid air gaps. Built on top of the insulation wooden frame, which will serve as the basis for future plating.

How to make heating in the garage with your own hands

Earlier we talked about how to choose the type of garage heating and make it yourself, in addition to this article, we advise you to read this information.

Now - directly to the workflow!

Instructions for insulating garage doors

The thermal insulation procedure consists of several stages, we will get acquainted with each of them in more detail. Traditionally, we will start with the selection of materials and the preparation of all the necessary equipment.

How to choose a heater?

In this case, the characteristics and quality of the heat insulator are extremely important. Of all the known heaters for our case, suitable:

• mineral wool;
• Styrofoam;
• polyurethane foam;
• extruded foam.

Each option has its own strengths and weaknesses. We also note that even before you insulate the garage door with your own hands, you should correctly determine the required number of materials. Go ahead.

If we talk specifically about polystyrene, then it does not have a high fire safety, but it has increased moisture resistance and low heat conductivity. Mineral wool more refractory (so to speak), but its moisture resistance leaves much to be desired. Polyurethane foam spraying is a new method of thermal insulation - expensive, albeit effective. This method has several significant advantages.

• After installation, there are no seams.
• Polyurethane foam weighs quite a bit.
• It can be applied to any surface, even unprepared.
• The material is resistant to temperature changes, exposure to chemicals, it is durable and strong.

But due to the high cost, this method is not very popular - as a rule, foam is used to insulate the garage door. Therefore, we will focus on this material in this article.

Necessary equipment

You will not need any specific tools - almost every car owner should have everything they need at hand. So, for work you should prepare:

How to insulate your front door

Earlier we talked about several ways of warming front door, what tools and materials are best used for this, in addition to this article, we advise you to read this information

Calculations of the required number of consumables

First, measure the gate and determine what and how much you need. Can be used for finishing various materials: plastic, plywood, lining, etc., but in practice the best option in this case is OSB boards, which have a number of advantages:

• reliability;
• affordable cost;
• strength;
• ease of processing;
• excellent aesthetic data;
• low vapor permeability (you can not use additional vapor barrier).

For a garage, you will need material labeled OSB-3 or OSB-4 one centimeter thick. At the end of the measurements, calculate the required number of plates (for reference: the standard dimensions of one plate are 250x125 centimeters). Often a couple of plates are enough, and after work there are a lot of scraps that will also come in handy in the future.

OSB-plates will be fixed to the crate, made of wooden bars 40x40 millimeters. The crate will be created along the perimeter of the structure and along the area of ​​the door leaf, and attached to the supporting parts (profiled pipes or steel corners can act as such). When calculating the dimensions of the crate, you need to take into account several points (this is another important point regarding how to insulate garage doors with your own hands).

• Load-bearing dimensions.
• Styrofoam sheet dimensions.
• The step of fixing the future skin (at least 400 millimeters).

The bars will be fastened with self-tapping screws (their length depends on the thickness of the supporting elements), for OSB boards, the best option is screws equipped with a press washer.

Note! It may be necessary to treat the inner iron surface with a special anti-corrosion primer that can protect the material from rusting. The primer can be any, it is only important that it is intended for a fairly wide temperature range. Before applying the primer, the surface will need to be degreased with a solvent.

To mount the foam to the metal (as well as to fill the resulting gaps), you need to purchase mounting foam. It is desirable that it be professional, that is, a special gun is used for application. The expansion of such foam is smaller, and it is much more convenient to apply it with a gun.

Wooden blocks should be treated with an antiseptic so that they do not rot. An antiseptic can also be anything; moreover, it can even be a paint with antiseptic characteristics. Finally, ordinary foam plastic (not extruded) must be protected from moisture, for which you can use bitumen-based mastic, vapor barrier membrane, isolon, and so on.

Stage four. Preparatory activities

Step 1. First of all, process everything wooden elements with an antiseptic. Do this in one or two layers, depending on the specific product (if there are several layers, then each of them must be given time to dry). To apply, use a regular brush, but start working only in protective gloves- most of the antiseptics are made on the basis of aggressive chemicals.

Step 2. Next, proceed to the preparation of the inner surface garage doors. Carefully inspect the surface, clean off any traces of rust found. Any paint that has already peeled off should also be cleaned. Further, in order to increase adhesion, the entire surface is carefully processed with sandpaper. Finally, the metal is coated with a degreasing solvent.

Step 3. Start applying an anti-corrosion primer, and apply it in two layers: the first - along the canvas, the second - across, after the previous one has completely dried.

Step 4. When the surface dries, proceed to waterproofing (as noted above, this is a prerequisite for ordinary foam). There are several ways to waterproof, let's get acquainted with each of them.

• By means of mastic based on bitumen.
• With the help of isolon.
• with a vapor barrier membrane.

It is necessary to cover the entire surface with waterproofing, which will later be covered with a heat insulator.

Stage five. Lathing installation

We continue to consider how to insulate garage doors with your own hands. According to the previously drawn up scheme, cut the bars the right size. To attach them, make holes in the frame with a diameter of 0.4 centimeters in increments of about 20 centimeters. To fix the bars themselves, you need to tighten them with clamps and, using a 0.25 cm drill, make holes in them along the depth of the screws.

Stage six. Styrofoam laying

The foam will be laid in the voids between the bars of the crate. To do this, first measure the dimensions of the cells and cut the insulation using a metal ruler and a mounting knife. It is important that you make each sheet of foam a few millimeters larger than the required dimensions, and on each side. So the insulation, being sufficiently elastic, will fit extremely tightly.

Video - Styrofoam cutting technology with a knife

There are several ways to fix the heat insulator between the bars of the crate, let's get acquainted with them.

Method number 1. The foam plastic can not be fixed at all, since the skin plates will already press it tightly against the gate.

Method number 2. The material can be glued using mounting foam. A great option, especially since foam is already required in the work.

Method number 3. Finally, you can use "liquid nails" glue, which, as far as is known, is intended specifically for this.

Note! The mounting foam has excellent adhesion, but it is still desirable to slightly moisten the surface before application. This is explained by the fact that the foam hardens exclusively when exposed to moisture.

Take a sheet of foam, apply foam on one surface around the entire perimeter (a little, in the center - in a zigzag pattern). After that, wait ten minutes for the material to increase slightly in volume, and press the sheet to the desired location on the gate. After another fifteen minutes, re-press the foam in order to make sure that its adhesion to the surface is as strong as possible.

After attaching the last sheet, blow out all the voids and cracks with the same mounting foam. When the foam dries (and this will take at least a day), the excess is cut off with a knife. Now proceed to the last stage of work!

Stage seven. sheathing

Measure the gate with a tape measure and determine exactly how the OSB boards should be cut. It is important that they completely cover the crate with insulation, but at the same time it is necessary to act on the principle of the ultimate integrity of the plates. If joints cannot be avoided, then they should be placed exclusively on the bars.

For cutting boards, you can use electric jigsaw or a hacksaw. Next, the plates in place, if necessary, make cutouts for ventilation holes or locks. For fastening, use screws - it will not only be reliable, but also look beautiful. The vertical fastening step should be 150 millimeters, but the center and horizontal - 250 millimeters. Drive screws into pre-drilled holes.

Note! If there are difficulties with the tightness of the doors or gates, you can paste over the problem areas with a sealant tape or a tube (these are sold in large assortment and you can choose for yourself optimal sizes and form). Thus, you will significantly reduce the heat loss of the garage room.

gates sheathed OSB boards, already look great on their own, but if you wish, you can paint them with paint of any color you like. Of course, all this depends solely on personal preferences, since the main thing is already ready - the gates in the garage are insulated. For a more detailed acquaintance with how to insulate garage doors with your own hands, we recommend watching the thematic video below.

Video - Thermal insulation of the garage door

As a conclusion

As a result, we recall once again how important it is to insulate the gate and the garage itself as a whole. Even the usual (not taking into account winter) temperature fluctuations during warm and daylight hours can lead to condensation in the garage. A permanently high level of humidity negatively affects not only the condition of the room, but also the body of the vehicle: metal surfaces become rusty, electrical wiring begins to rot, and mold or fungus appears in the corners of the garage. As soon as the condensate freezes, the finishing material will begin to crack due to moisture. But high-quality insulation will allow you to get rid of all these troubles!

Since the garage is not only the place of residence of your favorite car, but also the personal territory of its owner, it should be warm and moderately aesthetic. Then it will be pleasant to be here at any time of the year, and it is not a shame to accept friends. Therefore, the question of how to insulate garage doors must be addressed responsibly and competently.

Types of insulation

The market offers a lot of materials: both budget and more expensive. However, not all are suitable for a garage.

Styrofoam

Well-known, and most importantly reliable, cheap, simple material. Extruded polystyrene foam is also in demand, but it is much more expensive. True, it is more durable and a 3 cm thick plate can replace a 5 cm foam one.

Polyurethane foam

Controversial case. Some argue that it is enough to buy several cylinders of foam, from which it is easy, reliably to fill the frame of the crate. And for half a century you can forget about the problem. Others are not so optimistic: outdoors in the conditions of vibration that is present in the garage, it will not last even five years.
Perhaps you mean polyurethane foam. She has all the necessary properties of a garage heater:

• thermal conductivity level;
• complete immunity to moisture;
• ease of installation: it fits on the metal evenly, tightly, without the slightest gaps, becoming a monolith with the base.

The best recommendation: it is polyurethane foam that fills elite sandwich panels.
However, it is impossible to carry out the work on your own: you need to involve a master with special equipment. Therefore, the price is prohibitive for many.

"Astratek"

Coverage in 1mm of this thermal insulation paint, according to the instructions, replaces a five-centimeter layer of cotton insulation, that is, 50 times thicker. However, this innovation does not come cheap. It is usually applied with a roller or brush.

Cotton wool

It is represented by several modifications with different fillings: glass wool, slag wool, basalt and others.
Pros:

• low level of thermal conductivity;
• affordable price.

Minus: high hygroscopicity. Cotton wool, regardless of the type, quickly absorbs moisture, crumples, decreases in volume.
Use is possible subject to the installation technology or in a dry climate.

Preparatory stage

It must be carried out before insulating the garage door from the inside, since the metal, although reliable, requires certain conditions in order to remain so for a long time.
The gate is a structure not designed for loads, therefore, super-strong steel grades are not used for their production. This has advantages: lower price and ease of working with such metal. However, the gate is strongly affected environment so corrosion is inevitable. So that the metal does not rust in just a couple of years, the simplest algorithm is used:

1. The surface is thoroughly cleaned old paint, rust and other debris. Instead of traditional sandpaper or a manual metal brush, you can work with a metal core brush attachment.
2. The cleaned iron is degreased with acetone or another alcohol-containing solution.
3. Primer. Better buy special agent. The cheapest but not The best way- paint with oil paint.

Quality durable paints and varnishes roads, and knowledgeable people it is advised, if there is a shortage of funds, to use any composition on a bitumen basis. They are not particularly aesthetic, but this is not necessary, because the surface will subsequently not be visible.

crate

In order for the garage door insulation to be of high quality, and the insulation itself to “sit” securely, a frame is mounted from wooden bars or thin metal profile. It is fastened inside to the stiffening ribs or the edges of the gate with metal screws or screws. 4-5 holes are drilled for self-tapping screws per meter.
The construction of the cells is equal in thickness to the reinforcing cage or slightly larger, in length and width corresponds to the dimensions of the insulation. Before starting work, the wood is thoroughly treated with an antiseptic and other protective compounds. A cheap reliable method is impregnation with well-heated drying oil. This is necessary so that fungus or something like that does not appear.
The crate is also made if the final sheathing of the gate is planned, which is attached to it.

We insulate the gate

There are a lot of materials and ways to insulate garage doors with your own hands. They are selected depending on the climate, the financial capabilities of the owner, personal preferences.

Styrofoam

The simplest and budget way. Required:

• foam in sheets;
• glue (preferably "liquid nails");
• assembly foam.

Gates of any design are reinforced with a pipe or corner with a thickness of 4 - 5 cm. It is under it that the foam is selected. The sheets are cut and fixed to the base.
If the garage door is insulated with foam plastic using glue, the foam plastic is placed tightly, without gaps. It must be firmly pressed to the surface until the glue dries completely.
When working with mounting foam different workflow:

1. You need to leave a gap between the sheets so that the sting can pass through. mounting gun, that is, about half a centimeter.
2. The foam strips are applied in any order in an even layer, and the foam is applied to the base after a few seconds.
3. Since the foam expands, every 15 to 20 minutes you need to re-press the sheet to the base.
4. When the sheet is securely glued, all gaps are sealed with the same mounting foam.
5. Excess foam after solidification is cut off.

Styrofoam itself is not intended to be a finishing material, therefore it is not particularly aesthetic. For beauty, you can use, for example, isolon. This is foil-coated polyethylene foam with a thickness of half a centimeter. It is pasted on polyfoam, as usual wall-paper. At the same time, the thermal insulation is increased. But this beauty is rather fragile.

Styrofoam plus crate

A method for people who prefer to immediately decide how to insulate garage doors with polystyrene foam thoroughly and aesthetically.
If the foam plastic fits tightly into the crate in thickness, you can not glue it, but simply insert it and process the joints with foam. If it is thinner, then it is necessary to glue it so that it does not hang out. After that, if desired, sheathe with some material, for example, clapboard.

Cotton wool

The preparatory stage is the same as for foam: the metal surface is well cleaned. When using this heater, one thing should be taken into account. The metal has a high thermal conductivity, so condensation forms inside the cotton layer.
The buffer layer between the metal and the cotton cloth can solve the problem. Painting, thin foil membrane or polyethylene is not enough. A more voluminous foil isolon is ideal.
They paste over the inner space, after which cotton mats are inserted into the crate. They are fixed on the sides with dowels and insulated from above with a film. Suitable ordinary technical polyethylene, attached to the crate with a stapler.
In order for the cotton sheets to sit tightly in the crate, the size of the wooden cells should be half a centimeter smaller than the sheet.
The finish layer can be plywood or other similar material attached to the crate with self-tapping screws.

Perimeter seal

Not less than important factor, without taking into account which the insulation of the garage door with your own hands will be useless.

Entrance door

When choosing a gate, you should prefer a model with a regular door. This is a little more expensive compared to a solid canvas, but it pays off with the energy savings for heating the garage.
It is obvious that repeated opening of the overall sash will carry away much more heat than a door that is several times smaller in size.

cracks

It is unrealistic to ensure an absolutely tight fit of the valves around the entire perimeter of the opening. Materials used indoors for windows or doors are not initially suitable. For garage doors - solid metal structure– Appropriate accessories are manufactured. Good decision rubber hoses, hollow or filled with foam rubber or other similar material. The sealant is sold together with the strap or, in its absence, is attached to the base with self-tapping screws using mounting straps. If the slots are very large, rails are additionally used, and brush profiles are placed in the lower part.

Curtain

An accessory familiar to car service customers is available in several versions.

Thermal curtain

Operates on the principle of a fan heater, cutting off cold air right at the entrance. However, both the unit itself and the electricity it consumes are expensive.

Tarpaulin

The same classic sliding curtain, only with water-repellent impregnation. It is mounted simply: a baguette is strengthened over the gate or a metal string is pulled. It is easy to hang tarpaulin curtains on them.

Tape

It is made from vertically placed ribbons above the entrance. Dense technical polyethylene is cut into strips 10–15 cm wide. They are fixed with a stapler on a wooden rail with an overlap of a centimeter and a half. From above, everything is pressed with the same rail for reliability.
Whatever the curtain, it should not reach the floor, but be a couple of centimeters shorter.

Finishing

The interior design is not limited to the mentioned clapboard, plywood or isolon. The following options are no less popular:

• siding;
• galvanized iron;
• chipboard boards;
• PVC panels.

They are attached to the crate with glue or self-tapping screws, the joints are treated with silicone sealant. The surface can be primed or painted. When deciding how to sheathe the gate, you need to take into account the main requirement for materials - incombustibility.
Insulating garage doors with your own hands is not so difficult. Materials are available in different price and quality. If everything is done correctly, it will be pleasant and safe here for both the car and its owner.

A garage is a parking place for a car that protects equipment from the weather and a workshop if the car needs repairs. Some inhabitants store inventory, country supplies for the winter, and old things in this room. For a comfortable stay in this room, you need to warm it.

Many do not know how to insulate the garage door from the inside. You can do this work with your own hands, following the special instructions described below.

Preparation for work

There is an option that is easy to use, but very expensive - to buy a garage door model with built-in insulation and interior decoration. Do-it-yourself garage door insulation will cost much less. This does not require any construction education or experience in finishing works, and it will take a little time to warm up. Consider how to properly insulate garage doors with your own hands with all the nuances.

Garage doors are made mainly from sheet steel, so they cannot keep the heat in the room. It is impractical to heat an uninsulated room, as it is possible to get condensate in the room and frost on the walls and gates when severe frosts. Before sheathing the gate in the garage, purchase the material that will insulate the garage door.

You can use different heaters, the cheapest and most effective option would be to insulate the garage door with polystyrene foam.

• Styrofoam has a small specific gravity, so there will be no load on the structure. The material has low thermal conductivity, is environmentally friendly, lasts more than 50 years and does not absorb water. To install thermal insulation, special tools are not needed, since the foam sheet is easily cut with a simple clerical knife.
• stone wool(basalt) - fire-resistant fibrous material, with high moisture resistance. It is used in any premises for sound and heat insulation, does not emit harmful substances. This material is easy to use. Sold in rolls.
• Expanded polystyrene- one of the varieties of foam plastic having the same composition. This material has a lower thermal conductivity due to its increased density, and has a different degree of flammability, which is indicated on the package. For insulation of garage doors, you need to use the brand NG or G1. This material has a drawback, it collapses in the sun, and therefore requires additional finishing.
• Liquid penoizol- material that is sprayed from a cylinder and is able to fill all the cracks and bridges of cold. Sets in 15 minutes, cures in 4 hours, final strength is achieved in three days. The advantage is ease of use, good thermal insulation qualities, incombustibility. The insulation is seamless, no need to rack your brains - how to close the gaps between the sheets of material.

It is better to order a gate with a gate to the garage, if it is not provided, then it is better to equip it before the start of insulation work. The wicket will help keep the heat in the room during repair work.

Insulation tool

Before insulating garage doors, you need to prepare the tools necessary for this process:

• screwdriver or drill;
• core;
• screwdrivers;
• square;
• level;
• hard brush;
• sandpaper;
• roulette;
• hacksaw;
• construction knife.

Almost every owner has this set of tools.

Finishing materials

Even before starting work, you need to decide how to sheathe the gate in the garage:

• lining;
• corrugated board;
• plywood, moisture resistant;
• PVC panels.

Based on practice, it can be noted that the oriented strand board (OSB) has a lot of advantages:

• strength and reliability;
• easy to process;
• does not need additional vapor barrier;
• moisture resistant;
• has an attractive appearance;
• is inexpensive.

This material is suitable for rooms with high humidity.

To make a frame for insulation, you need to prepare bars with a cross section of 40 mm, which are pre-treated with special antiseptic formulations, to prevent rotting.

Preparing the gate for insulation

Before insulating garage doors, preliminary preparation is carried out. Conduct a garage inspection swing gate for rust and peeling paint. They need to be cleaned well, rust is removed with coarse sandpaper, paint with a stiff metal brush. Further, the entire surface is treated with fine-grained sandpaper for better adhesion.

The next step is to treat the surface with a degreasing solution. After complete drying, an anti-corrosion primer is applied in two layers. It is worth noting that the second layer of primer is applied after the first has dried and perpendicular to it.

The primer is followed by waterproofing, it is equipped if foam plastic is used as a heater, it is optional with other materials. Easy to use bituminous mastic, which the door leafs are carefully smeared with, while it is desirable to glue vapor barrier membranes on it. You can use self-adhesive material "Izolon"

crate

When insulating the gate from the inside with your own hands, you must strictly adhere to the instructions described below - this will help you not to make fatal mistakes.

Lathing - installation of bars, previously sawn to the size of the door leaf. It is desirable that the bars are solid. Do not neglect the framing of the deadbolts and vents around the perimeter.

Before installing the bars, you need to mark the door leaf and tilt the places where the holes for the fasteners will be. The step between the screws should be no more than 25 centimeters. It is necessary to pre-drill the holes with a 4 mm drill, at the previously marked places.

The bars are screwed with self-tapping screws (wood-metal) of the required length. To do this, use a screwdriver. The bars should be 60 centimeters apart - this distance just fits the width of the foam layer.

Foam installation

Insulation of swing garage doors with foam plastic begins with marking and cutting the material. The cutting of the layers must be done in such a way that the foam plastic fits tightly between the crate. The cut line must be even and vertical, so the use of a flexible blade is unacceptable.

It is worth noting that you can not use fasteners for foam when installing it, as it will be taken as a finishing material. But for reliability, you can use special silicate glue or mounting foam, which can also be used for sealing seams and crevices.

Tip: you need to buy material taking into account the crate and its location on the canvas of the swing garage doors, otherwise there will be a lot of scraps. You can use expanded polystyrene for insulation, then additional waterproofing is not needed, and it is easier to work with it - it does not crumble. The only drawback is the high cost.

Stone wool in the insulation of the gate

How to insulate a garage door from the inside stone wool will not be difficult even for a beginner. This good insulation, which has an aluminum film on one side, which reflects heat by 97%. Mounted directly on the door leaf with mounting adhesive. From the side of the garage, the insulation must be protected with any facing material.

The use of expanded polystyrene

For garage doors, many use such a heater as polystyrene foam, which has good insulating qualities. The installation method is the same as when installing the foam.

Insulation of the gate with penoizol

Do-it-yourself insulation of garage doors with liquid penoizol will not work - this will require special equipment and qualified builders. The material is sprayed in several layers by a spraying machine. The crate for this method is mounted as in the previous case, it will be needed to attach the finish.

This method has a large number of advantages:

• does not change its properties over time;
• excellent adhesion;
• high thermal insulation properties;
• when applied, there are no bridges of cold;
• does not require the installation of a vapor barrier;
• service life of 70 years.

The use of mounting foam

Once the layers of insulation are installed, you need to carefully cover the gaps. The best and simplest option would be to isolate the garage door with mounting foam, it fills all the voids and cracks.

It is better to purchase professional material for the gun, this will help to significantly save material, since the gun helps to accurately distribute the foam in the right amount. The foam tends to expand, thereby filling all the voids. As soon as the foam dries, it is cut flush with the insulation.

How to cover the gaps between the base and the insulation? To do this, you can use "Izolon" - a self-adhesive material used as additional insulation and vapor barriers.

When insulating, it is often used to lay the door leaf with penofol, before starting the installation of the crate. It is an innovative, non-flammable, easy-to-use insulation material.

Gap insulation

When the gate is insulated, gaps remain between the door leaf and the slopes, into which cold air penetrates from the street. For complete tightness, these cold bridges must be eliminated without fail. For this, inserts and thresholds are used.

Vinyl inserts do an excellent job with this problem. They glue the edges of the gate, after covering them with two layers of paint. For better adhesion to inside inserts have special notches.

Before installing the inserts under the threshold, the space is pre-cleaned from dust and dirt. The material is fastened with a special mounting adhesive.

Garage door insulation

Before you insulate the door in the garage, surface preparation is carried out. You need to do it in the same way as with the insulation of large swing gates. Equipped with waterproofing, and vapor barrier.

After that, the crate is mounted with pre-prepared bars. First of all, they are screwed around the perimeter of the gate. Then you need to cut out a bar equal in size to the diagonal line of the gate and fasten it with self-tapping screws. The crate is ready, it needs to be treated from decay with special compounds.

Insulation in the case of a gate is cut in the form of two triangles, and inserted tightly into the crate. All cracks are foamed, as described above.

Finishing the gate after insulation

As soon as the insulation of the canvases with their own hands is completed, the question arises - how to sheathe the garage doors. There are a lot of options, you can apply:

• Rail car - which is an inexpensive environmentally friendly material. She has presentable appearance, it tolerates temperature extremes well, is resistant to mechanical damage. Gates, hinged, insulated, and trimmed with clapboard have an aesthetic appearance. It is mounted on wood screws to the gate crate.
• PVC panels are easy to maintain, installation is easy, long service life. But there is a downside, this stuff beat bumps and mechanical damage. The panels are mounted on the crate using a construction stapler.

• moisture resistant plywood - a material with excellent characteristics in terms of ecology and technical qualities, the only negative is the high cost.
• OSB panel - A high-quality, inexpensive material for facing work on garage doors, which even professionals advise using.

The material is mounted on the crate using self-tapping screws. Before installing on garage doors, swing doors need to be cut to size, trying to eliminate a large number of scraps. OSB has excellent characteristics, but it needs to be treated to increase its service life. special formulations, or paint.

In custody

As you can see, the work on insulation is painstaking, but not difficult, and if it is done in accordance with all the rules, then the insulated garage doors will protect the room where the car is located from winter frosts.

It is worth considering another important nuance - you should not use material such as mineral wool to insulate garage doors. The fact is that it absorbs moisture, which, when frozen, almost completely deprives the material of thermal insulation abilities. This fact also applies to glass wool.

Do not forget that when cold and warm air come into contact, a dew point appears - condensate, which, if the insulation is not installed correctly, can reduce all work to zero. Now you know how to properly insulate the gate in the garage and you can do it yourself.

The microclimate in general and the air temperature in the garage in particular are parameters that directly affect the safety of the car and all other items in the room. In order for the garage to become the most reliable shelter for your property and comfortable place for repair and other work, you need to perform complex insulation the entire structure and pay special attention to the thermal insulation of the gate. You can handle all the stages of warming with your own hands. Read the instructions and get to work.

In order for the thermal insulation to be as effective as possible, you must not only properly fix the insulation, but also first take all possible measures to keep the heat in the room. For example, examine the state of your gate. Maybe they are already very thin and it's time to install them instead modern design good quality? Of course, this rarely comes to this, but even such unpleasant exceptions occur.

As a rule, the walls of the garage have a relatively small thickness. Without high-quality insulation, they will practically not retain heat inside the garage. And even the most modern heating system will not help - condensation will simply begin to settle on the walls, which will lead to even more adverse consequences.

Therefore, the first thing you should do is to insulate all the surfaces and ceilings of your garage, and only then think about organizing a heating system. And the thermal insulation of the gate is an integral part of the mentioned complex work.

Prepare in advance all the necessary accessories for insulating the gate. It is better to spend time assembling them at the very beginning so as not to be distracted by this in the future.

5. Dowel.
6. Fasteners for steam, hydro and thermal insulation.
7. Sealing composition.

It is better if the garage door insulation is external. However, this task is very often not possible. If the garage is located on a private adjacent territory, then it is still possible to insulate its gate from the outside. In the case of placing a garage in a cooperative, you will have to be content with internal thermal insulation.

Condensation will form at the points of contact between the insulation and the metal of the gate. Therefore, the metal parts of the structure must first be treated with a special anti-corrosion agent and covered with a vapor barrier material.

After laying the vapor barrier, a wooden frame is attached to the gate with cells according to the size of the heat-insulating material slabs. The insulation itself fits as tightly as possible.

Previously, the wooden elements of the frame must be impregnated with a special antiseptic. You can buy a ready-made composition or cook it yourself. Heated drying oil has good antiseptic properties.

Traditionally, mineral wool and polystyrene are used to insulate the gate.

Before starting work, take the time to properly prepare.

First stage. Clean the surface. Take a special power tool or at least an ordinary metal brush and remove corrosion, cracked paint and other contaminants from the gate.

Second phase. Prime the gate. To do this, buy a professional composition in a specialized store. The primer will protect the metal from corrosion. To apply the composition, it is convenient to use a wide brush.

Third stage. Seal the gaps between the frame and the garage door leaf directly. To do this, it is convenient to use a special sealing rubber. It will simultaneously close the gaps and will not prevent the gate from opening normally.

The foam insulation technology is extremely simple and easy to do with your own hands. Follow all the above recommendations step by step and your garage door will be securely insulated.

First step. Cut the styrofoam sheets according to the dimensions of the gate. If in the future you plan to carry out decorative sheathing, for example, with clapboard, fasten a crate of wooden slats. You will lay insulation in the cells of the crate, and nail the lining directly to the slats. If the finishing cladding is not planned, the crate can be omitted.

Second step. Lubricate the insulation plate or the surface of the gate at your discretion with mounting foam or with a special foam adhesive that can ensure its high-quality adhesion to metal surfaces. Foam must be present at the corners of the sheets. Also evenly distribute it along the plane of the insulation plate.

Keep in mind that as the foam gains strength, it increases in volume, so apply it as evenly as possible.

Step three. Press the foam sheet firmly against the surface to be insulated. In the absence of a crate, start insulating from the corner of the gate, carefully aligning each sheet before final fixing. Pre-metal is recommended to be slightly moistened with water.

We applied the foam to the sheet, waited a few seconds until it expanded a little, pressed the sheet tightly to the surface, pressed it again after 20-30 minutes. The foam expands, so you will most likely have to do several of these re-squeezes.

Fourth step. If desired, stuff lining or other finishing material of your choice on the crate.

Mineral wool is also often used to insulate garage doors. Preparation for thermal insulation is the same as in the case of foam: you clean the metal from dirt and fix the vapor barrier. In the case of mineral wool, it is imperative to prepare the frame. The frame cells should be 5-10 mm narrower than the mineral wool insulation board. So the plates will be laid as tightly as possible.

All wooden structural elements must be impregnated with an antifungal agent.

Fill all the cells of the frame with insulation. On the sides, fix the mineral wool plates with dowels. Fix the waterproofing material over the insulation. A simple plastic film will do.

On top of the heat-insulating "pie", wash the lining. Fasten the sheathing sheets to the crate using self-tapping screws. Instead of lining, you can use another material of your choice.

If you wish, you can use the simplest version of garage door insulation with the help of mounting foam in cylinders.

First stage. Buy mounting foam. For 7 m2 of insulated surface, about 5 cylinders of foam are used. Calculate the required number of cylinders to insulate the gates of your garage.

Second phase. Apply the foam to the gate in an even layer. Let the material dry, and then cut off the excess foam that has come out on the sides with a clerical knife or other sharp tool.

Third stage. If you wish, do decorative trim insulation. Foam is not very easy to hide. But it, for example, can be covered with plaster. The insulation will not be completely invisible, however appearance designs will immediately become more aesthetically appealing.

If you have a sufficient budget on top of the foam, you can arrange sheathing from chipboard, lining or other material.

As a result of such insulation, a real monolith will be created on the gate. The advantage of this method is that the foam is able to fill even the smallest gaps with high quality. This material is not afraid of contact with moisture and lasts for several decades. In addition, the foam layer will further strengthen the gate structure.

Successful work!

Every motorist knows how important it is to maintain optimal temperature regime in the garage. The condition of the car body and its technical systems largely depends on compliance with the temperature. In addition, during the cold period it will be much more comfortable to use for your needs. So, the car will not need a long daily warm-up of the engine before the upcoming trip. This saves you time and fuel costs.

Many car enthusiasts do not know where to start and, therefore, do not take into account many details. For example, the most common mistake is to heat an uninsulated or poorly insulated garage. In such a situation, you lose a large amount of resources without getting the proper amount of heat. In order to avoid such a situation, first of all it is necessary, and after that, to plan the heating system.

The first step is to insulate the garage door. We will answer the most pressing questions about thermal insulation:

Vehicle owners do not always approach the issues of car storage with due attention. Many people think that if there is a garage, then you should not worry about anything anymore, because in any case it is warmer in it in winter than on the street. So why insulate?

The fact is that the temperature during the day and at night quite often differs significantly. Such temperature fluctuations that are familiar to us can cause condensation in the garage room. A periodic increase in humidity adversely affects not only vehicle, but also on the condition of the room itself (mold appears, deteriorates, etc.). The body of the car in such conditions quickly begins to rust, work is disrupted electronic systems, and this in turn becomes unsafe for the driver. At temperatures below zero, the condensate freezes and expands, causing damage. This causes damage to absolutely everything where moisture has gotten.

It is also worth paying attention to the fact that garage doors need more insulation than walls. There are several reasons for this:

1. Metal is known to have high thermal conductivity. This means that the cold outside is due to iron gate will get inside.
2. If the metal is of insufficient thickness, then it will cool down much faster, while cooling the room.
3. When mounting the gate, gaps often remain, because of them, air from the street enters the garage, which contributes to the formation of condensate and temperature changes inside.

Thus, it becomes quite obvious that the garage doors without fail need to be insulated, and the room itself needs seasonal heating. This will extend the life of your vehicle and help keep your garage dry.

garage door insulation materials

Insulating garage doors is not particularly difficult, so it is not necessary to resort to specialized help. The main question that should be resolved before starting work: what material to choose for insulation? In any building supermarket you will find a huge range of materials for thermal insulation. If you have not had to deal with insulation issues before, then it will be extremely difficult to stop your choice on something specific. Therefore, we tried to consider the most popular materials that are used for thermal insulation.

Foam insulation

Styrofoam insulation is one of the most economical options. Styrofoam is inexpensive, while having a mass positive qualities. First, it is very easy to install. It weighs little and is attached to surfaces with plastic dowels or mounting foam. Secondly, the material is resistant to impacts and does not require additional coatings. In modern industries, a flame retardant is added to the composition of the material, a substance that prevents combustion and has self-extinguishing properties. The main disadvantage of polystyrene is its fragility, therefore, during installation, you should be especially careful.

Mineral wool

Mineral wool is a fiber structure insulation that is made from recycled basalt rocks or industrial metallurgical waste. The material is thin threads woven together and rolled into a roll or layer. Mineral wool has a low thermal conductivity, which provides good thermal insulation of the insulated room. Mounting such a heater is also not difficult. The disadvantage of the insulating material is its high hygroscopicity - it collects and holds moisture. Therefore, it needs additional waterproofing.

polyurethane foam

Polyurethane foam is considered to be the most high-quality and practical insulation. Even despite its rather high price. The following advantages of polyurethane foam insulation can be distinguished:

• easy to install and has light weight, besides, when laying, it does not leave joints and seams;
• can be applied to any surface without prior preparation;
• low thermal conductivity and high refractoriness;
• long service time;
• the possibility of any exterior decoration after laying.

The polyurethane foam is mounted with a sprayer, which ensures maximum insulation. Of the shortcomings, only the high cost can be noted, but it is quite justified.

Tools and materials

Polyurethane foam, although it has a lot of advantages, is not so often used due to its high cost and installation features. Therefore, we will consider an example of foam insulation. This material is most often used for thermal insulation of houses, garages and other premises.

In order to correctly calculate the required materials, it is enough to know the exact dimensions of the gate and the parameters of the materials used. However, in practice it should always be taken into account that in the process of work there may be different nuances. Therefore, it is always better to buy consumables with a small margin.

Necessary materials:

• insulation;
• material for the crate (wooden beam);
• inner lining (plywood, plastic, lining, chipboard - your choice);
• mounting foam;
• self-tapping screws;
• primer for metal;
• waterproofing for foam (izolon, vapor barrier membrane);
• wood preservative.

The right set of tools is usually not a problem for the car owner. But if something is missing, then it is better to acquire it in advance.

Equipment required for installation:

• electric drill;
• screwdriver or a set of screwdrivers;
• electric jigsaw or hacksaw;
• sandpaper;
• drills designed for wood and metal;
• clamps;
• iron brush;
• roulette;
• hammer.

Gate insulation: step by step instructions

Before you get started, make sure you have all the necessary materials and equipment. Also, think about safety measures and personal protection.

1. Surface preparation.

First of all, all wooden elements should be treated with a special antiseptic. This will protect the wooden beam from moisture and mold. It should be covered with a brush in several layers. inner surface the gate also needs to be prepared: clean out traces of rust (if any), process sandpaper to improve adhesion and carefully primed. Anti-corrosion primer is recommended to be applied in two layers: along and across.

2. Waterproofing

Foam insulation is not the most hygroscopic material, but still requires additional protection from moisture. To do this, the door leaf is carefully insulated. The material is not of fundamental importance, the main thing is that it performs its function.

3. Mounting the crate

This stage is very important, because installing the crate is not an easy task. It is important to do everything according to the plan. wooden beam must be cut into pieces of the desired size. Holes are made in the gate for fastening the timber, after which the crate is installed.

4. Laying insulation

Pre-cut foam insulation is placed in the voids between the bars of the crate. It should fit as tightly as possible to the crate. The foam is attached with mounting foam or liquid nails.

After laying the insulation, be sure to blow out all the cracks and voids with mounting foam. You can proceed to the next stage only after it has completely dried.

5. Sheathing

The first step is to cut the material for the sheathing. It is important to try to maintain the maximum integrity of the coating. The joints of the plates should be located on the bars. Cutting must be done carefully and accurately so that there are no gaps between the sheets. The sheathing is attached to the crate with screws. This is the easiest and most reliable way.

If desired, the skin can be treated for a more aesthetic appearance, for example, painted or primed with stain.

Do-it-yourself garage door insulation is completed. Such thermal insulation is durable and does not require additional care. Now, your car is not so afraid of frost and temperature changes. Warm air will not escape through cracks and metal gates will not cool the room. Thanks to the insulation, it will be much easier to maintain the optimal temperature regime.
