gratingspend time in the garage, caring for their "iron horses".However, in the winter to do the usual work is extremely uncomfortable, and before the owners sooner or later there is a question of warming the garage door. This measure allows you to solve the problem dramatically, since the heat escapes heat very quickly through the door leaf( and usually steel sheets).Warming a garage not only creates comfortable conditions for its owner, but also allows: - to start the car faster in extreme cold;
- extend the life of rubber parts;
- to prevent condensation in the internal cavities of the machine;
- create the desired temperature in the vegetable store, which is often combined with garages.
The possibility of gate insulation in the garage depends on their design.
What kind of door can you insulate?
Most doors have hinged doors, which are steel sheets welded to the metal frame. Warming of such gates is mandatory, since they practically do not trap heat. Make it easy, simple design swing gate allows the use of materials of any thickness.
The overhead and sectional doors for the garage are very popular at the moment. As a rule, they are factory made. Door leaf or individual sections are sandwich panels. From the outside they are covered with sheet steel, and from the inside they are already warmed with foamed polyurethane and do not need special measures for additional insulation. Self-made lifting gates are insulated in the same way as swing doors. The thickness of the insulation for them should not exceed the size of the frame. The same rule applies to recoil.

Rolling gates are not subject to insulation, since their design is designed for a certain thickness.
When choosing a material for insulation it is necessary to take into account its weight. The weight of the sash can lead to the fact that the mechanism by which the gate moves, will start to work worse over time and gradually fail.
The most popular materials for insulation
A good insulation should have a low thermal conductivity, then a sufficiently thin layer can significantly reduce heat loss. The following materials are most often used to insulate a garage door:
- Mineral wool and its varieties - glass wool, slag wool, stone wool. All of them are highly hygroscopic, so they need waterproofing. When working with them it is necessary to use protective equipment for hands and respiratory tract.
- Polyfoam. This word refers to a whole class of polymeric gas-filled materials, including polystyrene, polyvinyl chloride, urea-formaldehyde, and polyurethane foam foams. All varieties differ among themselves by greater or lesser elasticity, composition, sound insulation.
All foams have qualities that are indispensable for insulation of garage doors - low thermal conductivity and hygroscopicity, fire safety, chemical inertness.
How to insulate garage doors
Before starting work on insulation, it is necessary to check the efficiency of ventilation in the garage. In the process, do not block the ventilation openings with insulation. The normal operation of ventilation contributes to the reduction of humidity and the timely removal of gasoline vapors and exhaust gases.

Let us examine in detail how to insulate garage doors on their most common construction - hinged.
Surface Preparation
Carefully inspect the inner surface of the door leaf. Large areas affected by corrosion are brushed with iron bristles. If rust has covered most of the steel sheet, it is more convenient and faster to work with a drill or a grinder with a special round nozzle.
After thorough cleaning of rust and degreasing, apply anti-corrosion primer.
Fabrication and installation of the
batten As wooden batten or aluminum profile is used as the batten. Attach the crate to the frame of the gate. Material for crates cut to size. Wooden bars are impregnated with a compound of double action - from fire and rotting. The crate elements are attached to the frame of the sash with screws of suitable length. All accessories on the door leaf - locks, vents, trim crate around the perimeter.
Waterproofing and laying insulation
Before you insulate the gate in the garage with mineral wool, you need to observe some of the subtleties of handling this material. Of all its varieties, it is better to dwell on basalt wool from a reputable manufacturer. Before laying wool, care should be taken to waterproofing the material so that it does not absorb moisture. Good results are obtained by coating the inner side of the gate with bitumen-polymer mastic or finishing with Izon-type self-adhesive material.

After all the metal parts of the gate are covered with waterproofing, the insulation is cut into pieces so large that it is a few centimeters larger than the distance between the battens. This is done so that cracks do not appear, as mineral wool compresses with time.
It is most convenient to cut the insulation in the following way: lay a sheet of fiberboard on the floor, roll out mineral wool over it, measure it out and force it out with a sharp clerical knife.
A steam insulation film is put on top of the mineral wool and is attached to the bars with a construction stapler. After the vapor barrier, the heated swing gates are ready for final finishing. Facing is made by plastic or wooden lining, a professional flooring, sheets of OSP.Fastening the cladding material to the bars with screws with a press washer.
Laying insulation around the perimeter of the door
The door leaves very rarely fit close to each other. Usually a gap is formed between them, allowing the gate to close freely. To prevent heat from leaking through these gaps, various seals are used. As a rule, they are a self-adhesive strip with a rubber or foam rubber seal. This seal is not suitable for insulation of the lower part of the door. For these purposes, there are special brush strips. They are attached to the bottom of the gate with self-tapping screws. 
After all the gaps are closed, the insulation of the garage doors can be considered complete.
