All motorists know how important it is to maintain a certain temperature regime in the garage. Stable temperature has a beneficial effect on the safety of the car and its technical system. In an insulated room, there is no need to warm up the engine for a long time before the upcoming trip.
This reduces fuel costs and your time. In such a garage it is more convenient not only to maintain, but also to repair the car. However, many car enthusiasts have no idea where to start arranging a room and do not take into account some important aspects. For example, users often try to heat an uninsulated or poorly insulated garage.
In this case, a lot of energy resources are lost without receiving the required amount of heat in return. Therefore, you need to first solve the problem with the thermal insulation of the garage, and only then plan heating system. How to insulate a garage door - this will be discussed below.
Insulation garage doors
Reasons and features of insulating gates and doors in the garage
Sometimes car owners with a garage do not always pay due attention to car storage. For many users, having a garage eliminates all worries, as they believe that in winter it is warmer than outside. So is it necessary to insulate?
The reason is that there are noticeable temperature changes in the garage, especially during the off-season period. Such phenomena can be a source of condensation. Under these conditions, the car body quickly begins to rust, failures in the electronic system appear, which is fraught with the risk of safe driving.
A constant increase in humidity affects not only the car, but also the condition of the garage itself (mold forms, mildew appears, etc.).
The problem of insulating gates and doors especially arises in the case of car maintenance and repair, as well as when setting up a workshop in the garage. winter time. It is worth noting that most heat leaves the room through swing gates.
There are several reasons why heat loss occurs:
- Basically, gates are made of metal, which is significantly inferior in terms of heat conservation to the concrete from which the ceiling and walls are erected.
- Due to large area the gap between the doors is of considerable length and even with the smallest gap at the gate joint, the total heat loss will be large.
- Additional doors are often installed in one of the gate leaves, which also significantly affects heat loss. When installing them, you need to know in advance how to insulate the doors in the garage.
It is advisable to install insulation from the inside, as this will protect it from vandals and reduce the requirements for its aesthetics.
Built-in wicket door in garage doors Material selection
For correct calculation necessary materials, need to know exact dimensions garage doors, doors and characteristics of the insulation used.
Attention! To eliminate defects and other unforeseen nuances that arise, it is recommended to purchase consumables with reserve.
There are no special restrictions on the choice of insulation for garage doors. Whenever possible, attaching it to inside valves and without significant weighting, such a material can be considered suitable for use. In order to know how to insulate garage doors and what insulating material to use, you need to take into account some of its features.
Let's consider the most common heat-insulating products suitable for insulating garage doors:
- Fiberglass, felt, mineral wool . These products have the same parameters of vapor permeability and thermal conductivity, as well as the same specific gravity. But using them as insulation for garage doors is very undesirable.
This is due to the fact that the dew point will be located inside the insulation due to its small thickness, which leads to constant moisture during the off-season period. This phenomenon is inevitable when cold air leaks into a warm room.
- Reed and peat slabs. This insulation is suitable for use in a garage, but it has poor mechanical strength and is also quite expensive.
- Insulation made of polymer material. It is cheap, effective in use, but quite sensitive to external influences.
- Different types of synthetic material. With low thermal conductivity, polystyrene foam and expanded polystyrene are lightweight, easy to process and can be fixed to any surface without much difficulty.
Such heat insulators are the most convenient insulation for installation on garage doors. Use polystyrene foam or extruded polystyrene foam, there is a significant difference for of this coverage does not have: characteristic properties they have the same ones.
Different types of insulation for garage doors Tools and additional material
In addition to choosing insulation, before installing it you also need to prepare other materials and tools:
- Wooden blocks with an edge equal to the thickness of the insulation.
- Screwdriver and screws.
- Drill.
- Sheathing boards.
- Metal brush.
- Primer.
- Antiseptic.
- Polyurethane foam.
Decorative finishing materials will be required, which can additionally be used as a heat insulator along the entire perimeter of the gate.
Panel mounting tool Do-it-yourself insulation of garage doors
Once the insulation material has been selected (foam plastic in our case), additional materials have been purchased and tools have been prepared, you can begin work on thermal insulation. At the same time, one should not forget about safety measures and personal protection.
First of all, you need to do the preparatory work:
- First you need to cover everything with antiseptic wooden elements. This will protect the beams from the appearance of mold and mildew on them. The inner surface of metal gates and built-in doors also needs to be prepared for better adhesion: remove rust and dirt from the surface of the gate with a brush.
- Then carefully prime the treated canvas. When applying antiseptic and priming solution, it is recommended to apply them in two layers: along and across.
- Cut the beams so that they can be placed over the entire area of the sashes with a gap equal to the width of the foam.
- Install a sheathing, which, in addition to fixing the foam sheets, will serve as additional protection from mechanical influences.
- Make markings and cut the insulation blanks so that they are slightly smaller in size than the sheathing cells on each side (for better fastening).
- Moisten the surface of the valves with a spray bottle or sponge.
- Apply polyurethane foam as adhesive and waterproofing on the surfaces of individual lathing cells.
- Install the prepared foam plastic slabs into the niche of the sheathing and hold for some time until the insulation is fixed to the surface of the sash.
On a note! For installation of sheathing and various accessories in case of large thickness metal, you must first drill holes for screws.
After installing the insulation, you need to fill polyurethane foam all voids and cracks, and excess protruding along the edges can only be removed if it has completely hardened.
Insulating garage doors with foam plastic Final finishing work
When the main area of the gate is insulated, all that remains is to install insulation along the entire perimeter of the outer contour of the gate frame and doors.
Clarification! Swing gates, in fact, are two boxes welded from a corner and sheathed on top with sheet iron with an overlap to overlap the leaves with each other. The doors are designed similarly, only they are smaller in size and they are built into one of the halves of the gate.
Procedure:
- It is effective to use insulation made of elastic or porous material with a large cross-sectional size. Strengthening it to the edge of gates and built-in doors can be done either by gluing or using a metal plate.
- If your garage door has built-in entrance doors, you will need to install a locking mechanism into them. And in order to find out how to properly insulate internal lock in the garage, you need to take into account the extension of the locking bar (bolt). To insulate the lock, a fabric or rubber strip is used, which is pressed with a decorative metal plate along the entire perimeter of the locking mechanism.
- For protection and aesthetic appearance, the entire interior of gates and doors is lined with cladding material. Sheets of plywood, chipboard, plastic are suitable for this purpose, and you can also use planed boards. Here you need to cut the workpieces so that the joints of the slabs are located on the sheathing beams and, when installing them, maintain minimal gaps.
It is most convenient to fasten sheets of such facing material using self-tapping screws. After finishing the work, it is advisable to treat the cladding for the most attractive appearance: cover it with stain or paint it.
Garage doors lined with clapboard At this point the insulation can be considered complete. In case of high-quality and accurate work, garage doors will serve you a long period without additional insulation. Nowadays, sub-zero winter conditions and temperature changes during the off-season period are not particularly dangerous for your car. Cold air will not penetrate from outside through metal gates. As a result of the insulation performed, a comfortable temperature regime will remain in the garage, which means that you no longer have to worry about the condition of your car.
Insulation of garage doors and their timely repair - urgent need, since cold air passes through the structure into the room, and due to the temperature difference, condensation begins to appear. This adversely affects the technical condition of the car and the microclimate of the room itself. Most of the work can be done with your own hands if you have some in stock basic kit tools and have minimal construction skills.
Why do you need to insulate your garage door?
The comfortable temperature inside the garage allows you to use it at any time of the year. If the garage door was not initially insulated, then it becomes a source of significant heat loss. It is through them that heat freely penetrates into the garage in the summer, and in winter the heat escapes outside. Therefore, if the garage is used as a car repair shop or as a place to store things, insulation will provide a milder temperature regime and protect against condensation penetration. In such a garage, the car body is not at risk of corrosion, the electrical wiring is not at risk of rotting, and the walls of the structure are protected from fungus and mold.
Insulation of a built-in garage is especially important, because it is usually connected to the general heating system of the house. Accordingly, in the event of heat loss, heating costs will increase.
Important! Before insulation, you should take care of organizing the ventilation system! It should be both supply and exhaust. If the inlet hole was in the sash, then it cannot be blocked with insulation.
What types of structures can be insulated?
Selecting material for work in the garage
When selecting insulation, it is necessary to take into account some nuances. For example, mineral wool and other porous materials are not recommended as insulating materials, since they develop a dew point (the temperature to which the air must cool for the steam contained in it to condense into dew). Moisture accumulates in the pores, due to which thermal conductivity increases, and this negates the insulation effect. In addition, glass wool in use is quite hazardous to health; slag wool is characterized by residual acidity, so the most digestible option would be basalt wool, but subject to the use of a vapor barrier film.
The most preferred material for insulating garage doors remains polystyrene foam. This is a variety synthetic materials with a foamed structure, based on a polymer. Polystyrene foam is classified according to the type of polymer.
Thus, if resistance to increased load is not needed, then best choice there will be foam. In all other cases - polystyrene foam or polyurethane foam. It is not advisable to save on insulation so that the efficiency does not turn out to be minimal. The thickness of the layer largely depends on climatic conditions. If the temperature in winter does not fall below minus 25 degrees, then the thickness of the insulation should be:
Additional consumables and tools
Before installation begins, you need to measure the gate itself and determine the quantity additional materials. In particular, this is a sheathing on which insulation and facing material will then be attached.
To work you will also need the following set of household tools:
Preparatory work
Before starting work on insulating iron gates, they should be carefully prepared. If the canvas is covered with rust, old paint or dirt, then all this must be cleaned with a wire brush or drill attachment. After this, the surface is degreased and a suitable anti-corrosion primer is applied to it in two layers.
The next step will be waterproofing the surface of the sashes. This step can be skipped only if the gates are insulated with extruded polystyrene foam. If simple polystyrene foam is used, then this operation is mandatory. As insulation you can use:
Step-by-step production of sheathing
Options and work order
Foam insulation
Heat conservation with polyurethane foam
This type of insulation requires professional equipment and specialized knowledge. Polyurethane foam is sprayed in several layers using a special installation. Lathing in in this case is also needed, since the gate lining is then attached to it. This method has many advantages - excellent adhesion, excellent vapor barrier, long service life and very good thermal insulation properties. Before applying the coating, lock structures, bolts, and hinges must be covered with film and pasted over masking tape. All work is carried out wearing a respirator, goggles and protective clothing. After the insulation has dried, the excess is cut off with a knife.
How to use basalt wool
If the choice fell on mineral wool, then it should be products from well-known manufacturers. Before laying this insulation, waterproofing is required. The next step is to cut the wool into pieces so that they fit tightly inside the sheathing. A vapor barrier film is stretched over the insulation and secured with a stapler. Now the gate can be lined.
Lining from the inside after insulation
In order for the gates to look aesthetically pleasing after insulation, and for the thermal insulation to retain its properties as long as possible, they must be lined. The finishing material can be:
The cladding is mounted on screws using washers.
Additional techniques for proper thermal insulation
Heat leaves the garage not only through the door leaf, but also through the gaps between the doors. To avoid this, special rubber seals are used. round section with a diameter of 20 mm. They are fastened with self-tapping screws using a perforated steel strip.
Gaps under the gate can also allow heat to pass through. They are usually compacted with brush profiles. They are mounted quite simply - they are screwed with self-tapping screws in increments of 20 cm to the bottom of the sashes.
Also, to save heat, a garage curtain is used, which is hung at the entrance. The best option is a water-repellent tarpaulin, although you can also use PVC fabric. The curtain is hung on a cable or on a curtain rod, for which special rings are inserted into the material.
Video about the process of working with insulation
Options for repairing and adjusting faulty structures
Factors causing deformation metal structures like garage doors, quite a lot. This includes natural deformation from the vagaries of the weather, metal fatigue, subsidence of the opening, and the usual shrinkage of hinges. To correct the geometry of the opening, there are some methods that are available to any garage owner, provided they have a tool and an assistant.
Important! Instead of the row being removed, a channel (or, in extreme cases, a corner) is installed so that the structure does not collapse. After raising the garage door one or two bricks, a gap appears between it and the floor. It can be concreted by making an outward slope or installing a threshold.
Important! Both the washer and the ball must be made of carbide.
Important! The welding site must be additionally welded with a strip, otherwise it may break over time.
As you can see, it is quite possible to insulate the gates with your own hands, and there are no particular difficulties in this work. When you are faced with a similar task, you can solve it quickly using simple ways and tools.
A garage is a place to park a car, protecting equipment from bad weather, and a workshop if the car needs repairs. Some residents store equipment, summer supplies for the winter, and old things in this room. For a comfortable stay in this room you need to insulate it.
Many people have no idea how to insulate a garage door from the inside. You can do this work yourself, following the special instructions described below.
Preparing 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 finishing. Insulating your garage door yourself will cost much less. This does not require construction education or experience in finishing works, and it will take a little time to insulate. Let's look at how to properly insulate a garage door with your own hands, with all the nuances.
Garage doors are made mainly from sheet steel, so they cannot retain heat in the room. It is not advisable to heat an uninsulated room, since you can get condensation in the room and ice on the walls and gates when severe frosts. Before sheathing the garage door, purchase the material you will use to insulate the garage door.
Can be applied different insulation materials, the cheapest and most effective option would be to insulate garage doors with polystyrene foam.
- Styrofoam It 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, no special tools are needed, since the foam sheet can be easily cut with a simple stationery knife.
- Stone wool(basalt) – fire resistant fibrous material, with high moisture resistance. It is used in any room 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 polystyrene foam, having the same composition. This material has lower thermal conductivity due to its increased density, and has different degrees of flammability, which are indicated on the packaging. To insulate garage doors, you need to use the NG or G1 brand. This material has a drawback: it is destroyed in the sun, so it requires additional finishing.
- Liquid penoizol- a material that is sprayed from a cylinder and is able to fill all the cracks and bridges of cold. It sets in 15 minutes, hardens within 4 hours, and final strength occurs after three days. The advantage is ease of use, good thermal insulation qualities, and non-flammability. The insulation is seamless, no need to rack your brains about how to seal the gaps between the sheets of material.
It is better to order a garage door with a gate; if it is not provided, then it is better to arrange it before starting insulation works. The gate will help retain heat in the room during renovation work.
Insulation tool
Before you insulate your garage door, 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 cover the garage door:
- lining;
- corrugated sheeting;
- plywood, moisture resistant;
- PVC panels.
Based on practice, it can be noted that oriented strand board (OSB) has many advantages:
- strength and reliability;
- easy to process;
- does not require additional vapor barrier;
- moisture resistant;
- has an attractive appearance;
- It's 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 compounds to prevent rotting.
Preparing gates for insulation
Before you insulate your garage door, you need to preliminary preparation. Carry out a garage inspection swing gates for rust and peeling paint. They need to be cleaned well, rust is removed using coarse sandpaper, paint with a stiff wire brush. Next, 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, 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.
After the primer comes waterproofing, it is equipped if polystyrene foam is used as insulation; with other materials it is not necessary. Bituminous mastic is easy to use and is used to carefully coat the door leaf, and it is advisable to glue vapor barrier membranes to it. You can use self-adhesive material "Izolon"
Lathing
When insulating the gate from the inside with your own hands, you must strictly adhere to the instructions described below - this will help you avoid making fatal mistakes.
Lathing - installation of bars, pre-cut to the size of the gate leaf. It is desirable that the bars are solid. There is no need to neglect the framing of deadbolts and ventilation holes around the perimeter.
Before installing the bars, you need to mark the door leaf and tilt the places where the holes for fastenings will be located. The step between the screws should be no more than 25 centimeters. You need to pre-drill holes with a 4 mm drill in the pre-designated locations.
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 from each other - this distance is just right for the width of the foam layer.
Installation of foam plastic
Insulation of swing garage doors with foam plastic begins with marking and cutting the material. The layers must be cut in such a way that the foam fits tightly between the sheathing. The cutting line must be smooth and vertical, so the use of a flexible blade is unacceptable.
It is worth noting that you don’t have to use foam plastic fasteners when installing it, as it will get stuck finishing material. But for reliability, you can use special silicate glue or polyurethane foam, which can also be used for sealing seams and cracks.
Advice: you need to buy material taking into account the sheathing and its location on the swing garage door leaf, otherwise there will be a lot of scraps. You can use polystyrene foam for insulation, then you don’t need additional waterproofing, and it’s easier to work with - it doesn’t crumble. The only drawback is the high cost.
Stone wool insulating gates
The process of insulating a garage door from the inside with stone wool is not difficult even for a beginner. This is a good insulation material, having an aluminum film on one side, which reflects 97% of heat. Mounted directly on the door leaf using mounting adhesive. On the garage side, the insulation must be protected with any facing material.
Application of expanded polystyrene
For garage doors, many people use insulation such as polystyrene foam, which has good insulating qualities. The installation method is the same as when installing foam plastic.
Insulation of gates with foam insulation
It is not possible to insulate garage doors with your own hands using liquid foam insulation - this will require special equipment and qualified builders. The material is sprayed in several layers by a spray machine. The lathing for this method is mounted as in the previous case; it will be needed to attach the finishing trim.
This method has a large number of advantages:
- does not change its properties over time;
- excellent adhesion;
- high thermal insulation properties;
- no cold bridges remain when applied;
- does not require installation of vapor barrier;
- service life 70 years.
Application of polyurethane foam
Once the layers of insulation are installed, you need to carefully seal the cracks. Optimal and simple option The garage doors will be insulated with polyurethane foam; all voids and cracks will be filled with it.
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. Foam tends to expand, thereby filling all voids. As soon as the foam has dried, 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 barrier.
When insulating, the door leaf is often lined with penofol before installing the sheathing. This is an innovative, non-flammable, easy-to-use insulating material.
Insulation of gaps
When insulating the gate, gaps remain between the leaf and the slopes, into which cold air penetrates from the street. For complete tightness, these cold bridges must be eliminated in mandatory. For this purpose, inserts and thresholds are used.
Vinyl inserts cope well with this problem. They are used to paste over the edges of the gate, having previously covered them with two layers of paint. For better adhesion, there are special notches on the inside of the inserts.
Before installing the inserts under the threshold, the space is first cleared of dust and dirt. The material is fixed using a special mounting adhesive.
Insulating a garage gate
Before insulating a garage door, the surface is prepared. It needs to be done in the same way as when insulating large swing gates. Waterproofing and vapor barrier are installed.
After this, the sheathing is mounted using pre-prepared bars. First of all, they are screwed around the perimeter of the gate. Then you need to cut out a block equal in size to the diagonal line of the gate and screw it with self-tapping screws. The sheathing is ready, it needs to be treated with special compounds to prevent rotting.
In the case of a gate, the insulation is cut in the shape of two triangles and inserted tightly into the sheathing. All cracks are foamed as described above.
Finishing the gate after insulation
As soon as the insulation of the sheets with your own hands is completed, the question arises - how to cover the garage doors. There are a lot of options, you can use:
- Railcar - which is environmentally inexpensive pure material. She has a presentable appearance, she tolerates temperature changes well, and is resistant to mechanical damage. Gates, swing gates, insulated, and finished with clapboard have an aesthetic appearance. It is mounted on wood screws to the gate frame.
- PVC panels are easy to maintain, installation is not difficult, and have a long service life. But there is a drawback, this material beats blows and mechanical damage. The panels are mounted on the sheathing using a construction stapler.
- moisture-resistant plywood is a material with excellent environmental and technical qualities, the only negative is the high cost.
- OSB panel – High quality, inexpensive material for facing works, on garage doors, which even professionals recommend using.
The material is mounted on the sheathing using self-tapping screws. Before installation on garage doors, swinging ones need to cut the sheets to size, trying to eliminate large amounts of scraps. OSB has excellent characteristics, but it needs to be treated to increase its service life special compounds, or paint.
In custody
As you can see, the work of insulation is painstaking, but not complicated, and if you do it according to all the rules, then insulated garage doors will protect the room where the car is located from winter frosts.
It is worth considering one more 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 its thermal insulation abilities. This fact also applies to glass wool.
Do not forget that when cold and warm air a dew point appears - condensation, which, if the insulation is installed incorrectly, can reduce all work to zero. Now you know how to properly insulate a garage door and can do it yourself.
A damp and cold garage is not the best the best place for car maintenance. The owner is provided with problems with the technical condition of all its components. Accumulating condensation will damage not only the car body, but also the electrical wiring.
The main percentage of heat is lost through the doorway. Swing design made of steel has high thermal conductivity, so insulating garage doors will a good decision. Dealing with the walls and roof is a little easier than insulating a garage door. To do the work yourself, you will have to study methods and materials.
Along with its direct purpose, the garage is used as a workshop. In the cold season, even a short stay in the garage will require great strength will. It’s convenient to do it yourself in the garage minor repairs, and here it is so obligatory good ventilation. Basement smell, mildew and mold on the walls are not all the troubles. Staying in such a room is life-threatening. Often openings for supply ventilation They leave it at the gate. On the topic of how to insulate a garage door, there is a useful video at the end of our article.
Important! Ventilation openings must be left in the thickness of the insulation.
Purchasing a finished product
If you decide to install a factory-made structure in your garage, then the problems of how to insulate the gate will end there. New lift-and-turn and sectional devices already have a layer of polyurethane foam. Even roller shutter types of gates are sometimes insulated, but the possibility of using them for a garage is very doubtful. Narrow aluminum slats will not reliable protection from burglary, and their high thermal conductivity makes them unsuitable for our climate.
When ordering a gate, a swing system with a wicket would be a good option. It will significantly reduce the percentage of heat loss.
We choose the insulation wisely
The assortment is quite wide. Among the things that can be used to insulate garage doors, the most in demand are:
- Various types of foam plastics;
- Fiber insulation (glass wool, stone wool, basalt wool).
To make a choice, you need to take into account all the pros and cons of the materials.
Insulating gates with foam plastic
Polystyrene foam is very economical option. The class of foamed polymers is quite diverse. They have a gas-filled structure and vary in type of polymer. Let's consider the types of foam plastics:
- Polystyrene is the most used. They are designated PSB or PSB-S. Extruded polystyrene foam (EPS) - has low hygroscopicity and good fire resistance. Insulating your garage door yourself is one of the best options.
- Polyvinyl chloride or PVC panels. Similar in characteristics to EPSS. International PVC marking. High fire resistance.
- Urea-formaldehyde foam (UFP). Used for voids and cavities. Liquid composition CFP does not increase in volume after complete drying. Can also be used as garage insulation.
- Polyurethane foam (PPU). It is produced in the form of elastic foam rubber and polyurethane foam. Hard polyurethane foam adheres well to any surface. Good hydro and heat insulator. Fire resistant. Such insulation will be light in weight and suitable for any finish. Polyurethane foam will do an excellent job of thermal insulation of garage doors. A sprayer is used to apply the foam.
Fibrous materials
Among fibrous insulation materials we immediately exclude stone wool and slag wool. The first is extremely harmful to humans; slag will oxidize metal surface. Glass wool is dangerous to work with, but of all, it has average hygroscopicity. It is this quality that makes the use of cotton wool unsuitable for garages. The accumulation of condensate in a layer of material will reduce its thermal insulation properties. WITH vapor barrier film, you can use basalt insulation.
The process of insulating a garage from the inside
To insulate your garage door you will need the following tools:
- Electric drill;
- Drills for wood and metal;
- Hacksaw or jigsaw for wood;
- Metal brush or drill attachment (brush);
- Screwdriver.
Also don't forget about roulette, paint brush, hammer, angle and ruler, sharp knife, core, sandpaper and clamps.
A clamp is a means for clamping parts. They will be convenient for attracting slats to the gate frame.
The order of work will depend on the insulation and type of construction.
Preparing the sashes
1. Cleaning
Remove old paint, rust and all dirt. This can be done conveniently and quickly using a power tool with an attachment.
2. Priming
The applied primer will protect the metal from corrosion. To work, take a wide paint brush. Anti-corrosion primer is applied in two layers. One across and the other along the surface.
3. Elimination of gaps between the frame and the canvas
Take advantage rubber seal. It will not interfere with the operation of the mechanism and will close unnecessary holes.
Next, we will look at how to insulate garage doors from the inside.
We insulate swing gates with foam plastic.
Swing gates are durable, reliable and easy to use. The system consists of two steel sashes welded onto a frame made of a profile pipe or angle. Sometimes corrugated sheeting is used, but steel sheet 2-3 mm thick and stronger.
It is good when the insulation of swing gates is carried out by their manufacturer. Otherwise, you can insulate your garage door yourself.
After choosing the material, you should calculate how much is required. You also need to decide on the finish on top of the insulation. The final option with different types The gate trim can be seen in the video. There are many options for covering garage doors.
Types of facing materials:
- Lining;
- Profiled sheeting;
- Fiberboard or MDF panels;
- Waterproof plywood;
- OSB or OSB boards.
Experience has shown that the latter are more suitable for cladding. OSB boards are plates made from glued and pressed sawdust and wood chips. If you look at the photo of the product, you can see its composition of several layers. The layers have different arrangements, which gives the sheets special strength and flexibility. This finish is easy to process, has low vapor permeability and is very economical.
Advice! For rooms with a high degree of humidity, use OSB-3 or OSB-4 boards with a width of 10 mm.
The cladding will be fixed to wooden frame. The lathing is installed around the entire perimeter and on the area of the canvas. For fastening wooden frame Galvanized wood screws are used.
3.5*30 mm - for side surfaces
4.5*70 mm - for the end
Attention! If the gate frame is made of profile pipes, then the length of the screws increases by the amount equal to the section pipes.
To fix the finishing slabs to the sheathing, take screws with a 4.2 * 32 mm press washer.
Insulation boards are laid between the sheathing. The foam is attached with special glue or professional mounting foam. If you are working with foam, wait 5-10 minutes after application until the composition increases in volume. The main thing is to avoid empty spaces. The slabs must be tightly laid between the grate slats. Treat the slightest cracks with sealant. Leave the mounting locations for locks, valves and ventilation free.
Laying waterproofing
We install waterproofing between the metal and the insulation. This could be bitumen mastic, foil, or a vapor barrier membrane. Extruded polystyrene foam does not require waterproofing.
After installing the insulation, proceed to cladding. OSB is cut using a hacksaw or power tool. The fastening pitch is 10-15 cm around the perimeter of the frame, and 20-25 cm along horizontal beams and in the center. To wooden blocks not split, mark the holes thin drill. To achieve the best fit of the shutter or gate, you can additionally seal these places with tape.
A garage finished in this way will have a very neat appearance.
We carry out thermal insulation with mineral wool
If you choose this material, then a vapor barrier layer will be required. The waterproofing material can be a simple polyethylene film. A frame is also needed, between which the insulation is tightly placed. The slabs are fixed on the sides using dowels. You can choose lining as the gate cladding. Attach it to the frame of the structure.
Insulating a garage from the inside with construction foam
Another method of insulating garage doors with your own hands is polyurethane foam. Of the ways you can insulate garage doors with your own hands, this is the easiest way.
- Polyurethane foam in cylinders (consumption of 5 cylinders per 7m2).
- Spray the foam in an even layer (cut off excess material after drying with a sharp knife)
- Decorative finishing (the covering can be chipboard, lining or any other material).
The advantages of insulating garage doors with your own hands using foam are that the material penetrates even into small cracks. This will also strengthen the entire gate structure.
The safety of your premises and vehicle in proper condition depends on the quality of garage door insulation. And safety also depends on.
Reliable insulated the garage space becomes more suitable for the long-term presence of a car, things and people. Cold negatively affects your vehicle and ruins it. From cold air in the internal voids of the car, condensate, which causes corrosion.
Rubber elements deteriorate much faster in the cold.
In addition, if the air is too cold, the car may simply not start.
SNIP standards claim that in winter the temperature in the garage should be maintained at +5 and more degrees Celsius.
Garage doors require special attention. A significant part of the heat exchange with the external environment occurs through them. Heat leaves the gate in two ways. The first is through ourselves doors gate, through main surface.
Cold air "pulls out" thermal energy from warmer garage air, interacting with the surface of the door. Unprotected doors give off heat easily.
Second way– outflow of warm air through cracks and sash joints. Thus, to secure the garage, it is necessary to close both of these routes.
The following materials are suitable for thermal insulation of garage doors:
- mineral wool;
- polystyrene foam - regular and extruded;
- polyurethane foam.
Styrofoam combines good hydro- and thermal insulation properties. Polystyrene foam has a low density, its weight will not load the garage door. Foam insulation will last about 40-50 years. Its disadvantage is relatively low fire safety.
In terms of fire resistance mineral wool will be more preferable. The downside of cotton wool is its poor protection against moisture and dampness. Another method is to use modern polyurethane foam.
The cost of such coverage high, but it has many advantages. After applying polyurethane foam there will be no seams left. The building material is allowed to be applied to all types of surfaces.
REFERENCE: Polyurethane foam– durable and resistant coating.
How to insulate?
The easiest option is to install ready-made insulated gates for the garage. But this is not always possible. Often you need to do the thermal insulation yourself, with your own hands. In this case, the big advantage will be the reduction in cost.
You will save money if you decide to insulate your gates on one's own. The process will take little time and will not require special skills from the car owner.
As mentioned above, cold penetrates into the garage in two ways - through doors and through gaps in the design. Let's consider both options.
Do-it-yourself insulation of garage doors: 
Protective Barrier
How insulate DIY garage doors? First of all, you should decide on the choice of material. The most common solution is Styrofoam. To create a protective foam barrier, it is necessary to treat and clean the inside surface of the gate. Pay attention to rust and traces of paint.
After cleaning, apply a new layer paints or bitumen mastic. This layer will provide waterproofing. It is possible (but not necessary) to enhance protection against water plastic film. The second step will be installation battens. It is made from wooden beam. The size of one square of the sheathing is 35-50 centimeters.
Now we should do styling polystyrene foam The polystyrene foam is cut into pieces corresponding to the size of the sections in the sheathing (35-50 centimeters). The pieces are placed in the recesses of the sheathing. You can attach them glue or polyurethane foam. It will provide additional sound and waterproofing. Last step– finishing of the outer layer plywood or plastic. This is done to make it pleasant appearance and additional protection from the cold.
There is another insulation for garage doors - expanded polystyrene. This is a modern analogue of foam plastic.
How to insulate a garage door expanded polystyrene? In this case, it is much easier to insulate the gate. Creating a sheathing not required. The building material is glued directly to the gate. You can use it instead of glue liquid Nails.
In addition, one of the types of polystyrene foam is foil polystyrene foam does not require applying a waterproofing layer to the gate. Otherwise, the insulation process is similar to polystyrene foam. First, the sheets are cut and glued. After this they fasten outer layer- made of wood or plastic.
REFERENCE: Expanded polystyrene provides more reliable thermal insulation.
Sash joints and gaps
Through gaps A large volume of warm air leaves the garage. To prevent this, the gate joints should be reinforced vinyl tape. Tape with suitable dimensions is laid along the edges of the joints. For fastening, use nails or mounting adhesive. Vinyl tape will create an airtight layer of insulation that will prevent heat loss.
Other
How insulate DIY garage door? The garage can also be protected in other ways, not only by creating a thermal insulation barrier and insulating the doors.
Ordinary people can help with this question curtains. They are made from thick fabric, for example, tarpaulin.
In the interior, a strong steel thread is pulled along the gate. Curtains are hung on rings.
As a result, you get a kind of transition chamber, a transition gateway, like in a spaceship.
The second way is to create doorway at the gate.
If you open only the doors, and not all the gates, then the warm air will escape significantly less.
Conclusion
Garage doors give off heat in two ways - through joints/gaps and through ourselves doors. It will be necessary to create an insulating barrier for the sashes that will protect the interior from cold air.
Gaps should be sealed vinyl tape. It is secured using nails and mounting adhesive. Instead of tape, you can use other sealants, such as silicone.
In addition, you can create additional protection. For example, using curtains made of thick fabric or doors in the gates.
This will make it more difficult for the cold to penetrate inside. If you open only part of the gate (the door), you let in less cold air. The curtain acts as a protective “wall”, which also improves the overall thermal insulation building.
