The garage can be used for its intended purpose - as a parking lot for a car, as well as a workshop or warehouse where you can store inventory and various things. If you often do car repairs, then it is best to insulate the building. The most effective data work will be in the gate area. However, before carrying out such manipulations, it is necessary to familiarize yourself with the rules that state that it is better not to use porous heaters like mineral wool for the thermal insulation of the garage. This is due to the fact that the dew point will shift towards the insulation, it will get wet, its density and thermal conductivity will increase.
Material selection
You should not try to save money by ordering a gate without a gate. Its presence allows you to keep warm inside the garage. It is better to immediately make gates not only with a separate door, but also with insulation. Among other things, the building must be equipped with a ventilation system, which can be exhaust and supply. The supply opening can be made in the gate. Insufficient ventilation can create life-threatening conditions.
Insulation of garage doors can be carried out by differentmaterials, but one of the most effective is foam. This material has a low density, so the insulation will not exert additional loads on the structure. Polyfoam has a low coefficient of thermal conductivity, it does not emit substances harmful to human he alth, which is true under normal operating conditions. This thermal insulation does not interact with air and water, and the formed layer will last more than 50 years. Processing canvases is quite simple, for this you can use the available tools. It should also be noted that the water absorption of polystyrene is quite low and does not exceed 3%, but if we are talking about extruded polystyrene foam, then this figure is even less, it is 0.4%.
Thermal insulation of the gate: preparation of tools
If you decide to insulate the garage door with polystyrene foam, then at the first stage you need to prepare the tools. You will need:
- electric drill;
- screwdriver set;
- metal brush;
- screwdriver;
- wood saw;
- roller;
- core;
- clamps;
- angle;
- sandpaper;
- hammer;
- meter tape measure;
- metal ruler;
- construction knife.
Preparation of materials
In order for the gate to look attractive from the inside, you can use facing material, which is sometimes used as corrugated board, wooden lining, waterproof plywood or OSB. As showspractice, it is best to prefer oriented strand boards, as they have many advantages, namely: the material is quite strong and reliable, easy to process, has low vapor permeability and eliminates the need for vapor barrier membranes to cover thermal insulation. Oriented strand boards can be purchased at a low cost, and after completion of the work, the door will have an attractive appearance. For cladding, it is recommended to use OSB-3 or OSB-4 boards, the thickness of which should be 10 mm. Such material is intended for rooms whose conditions are characterized by a high level of humidity.
After you determine the size of the gate, you should calculate the number of plates. Each of them has standard dimensions of 1250x2500 mm. As a rule, the master manages with two canvases, and after the work, there are trimmings that can be used for other purposes. Insulation of garage doors is accompanied by the installation of a crate, on which facing materials will be attached. For the frame system, it is recommended to use wooden blocks of square section with a side of 4 cm. They are fixed on the bearing part of the gate, which are metal corners, sometimes a profile pipe. Be that as it may, the crate must be installed around the perimeter and on the area of \u200b\u200bthe canvas. The distance between the elements of the crate should be 40 cm.
Additional preparations
If the insulation of the garage door with polystyrene foam or polystyrene foam willbe accompanied by further installation of the finish, then before starting the installation of the frame system, the wooden bars must be treated with an antiseptic. Depending on the composition to be used, one or two coats may be required. It is necessary to produce these works with a regular brush. During the drying of the bars, you can do the preparation of the inner surface of the gate, for this the rust is cleaned to the metal, it is more convenient to do this with a brush-nozzle on the drill. It is important to clean all loose paint, in hard-to-reach places it is more convenient to use a brush with metal bristles. Sometimes experts advise resorting to the use of sandpaper, which the master must walk over the entire surface, this will improve the quality of adhesion of the primer to the metal.
At the next stage, the surface is treated with an anti-corrosion primer, it is applied in 2 layers. The direction of the second should be perpendicular to the first. As soon as you have waited for the surface to dry completely, you should take care of waterproofing, which is relevant in tandem with ordinary foam. If extruded polystyrene foam is used, then this operation is not performed. Waterproofing can be done with bituminous mastic, sometimes vapor barrier membranes are glued to the surface.
Tips for installing battens
When the garage door is insulated with your own hands, it is recommended to consider the photo even before the start of work, which will allow you to excludemany mistakes. At the next stage, the crate is installed, the bars of the required length are cut to the size of the gate, they must be solid. In those places where locks and bolts are located, as well as ventilation grilles, it is necessary to make a frame of bars, installing them around the perimeter. To fix these elements, several holes are drilled with an electric drill, the distance between which should be 25 cm. For this, a 4 mm drill is used. In those places where the bars will be installed in the end, the holes should be 5 mm. Before drilling, it is recommended to mark and punch places so that the drill does not heat up.
For reference
When the garage doors are insulated with their own hands, the crate is sometimes required without installing the facing material. At the same time, the installation of the lower row of horizontal bars may be accompanied by some difficulties, which consist in the fact that it is not possible to get the tool to hard-to-reach places. If you remove the gate, then these works can be carried out without problems, if not, then you need to attach the bar to the end, because the rest of the crate will take on most of the load from the facing material.
Insulation installation nuances
Insulation of metal garage doors is usually carried out with foam, it should be cut only after measuring the space between the bars. Left on each sideabout 3 mm of material so that the foam is placed tightly between the bars. When cutting, it is necessary to ensure that the blade enters the thermal insulation vertically, if the blade is flexible, then it can lead to the side, which will certainly break the cutting line.
Sometimes the insulation of garage doors with foam plastic is not at all accompanied by mechanical fixation of the material, because the cladding will press it to the base. You can use liquid nails, sometimes foam is used, which will come in handy later when sealing joints.
Recommendations from an insulation specialist
When insulating garage doors with polystyrene foam, it is recommended to use 40 mm slabs, which can have different sizes. When buying material, it is necessary to take into account the location of the crate so that cutting the foam is not accompanied by the formation of a large number of scraps. If possible, try to strengthen solid sheets of material. Experts recommend purchasing extruded polystyrene foam, since its water absorption rate is minimal, there is almost no need to protect such material from moisture, but such thermal insulation is more expensive. As practice shows, it is much easier to work with extruded polystyrene foam, it does not crumble when cutting.
Installation of crates for insulation
For the installation of bars, galvanized self-tapping screws for working with wood should be used, their size should be 3.5x30 mm, as forfastening of the side surfaces, then their fixation is carried out using self-tapping screws with dimensions of 4.5x70 mm, they are installed at the end. If the gate frame is made of a profile pipe, then the length of the self-tapping screws must be increased by adding the pipe section. Fasteners should enter the bar to a depth of 1/2 of the section; when installing the facing material, it is better to use screws with a press washer with dimensions of 4, 2x32 mm.
Priming
Insulation of garage doors is usually carried out only after applying a primer to the metal surface. To do this, use an anti-corrosion agent that prevents the formation of rust in high humidity. The primer can be any, based on alkyd or synthetic resins. It should be designed for use over a wide temperature range. In order to degrease the surface, together with a primer, you must purchase a solvent.
Insulation with polyurethane foam
Insulation of garage doors with mounting foam is accompanied by the use of polystyrene foam or expanded polystyrene. As soon as the insulation plates are installed to the metal surface, all joints must be filled with mounting foam. It is better to purchase its professional variety, which involves the use of a pistol. Such a composition expands less in volume, and the gun allows you to conveniently apply the mixture to the right place and in any quantity. In order to prevent rotting of the bars, an antiseptic should be used, it can be made on an oil or water basis, sometimes such mixtures arepaint with antiseptic properties. If you decide to use ordinary foam, then it should be protected from moisture. This can be done using a vapor barrier membrane, Izolon self-adhesive insulation or bituminous mastic.
Insulation of sectional works
Insulation of sectional garage doors is carried out using almost the same technology as described above. Before starting, you need to choose a material, which can be foam, its installation is carried out using plastic dowels. This material is resistant to mold and mildew. If you want to ensure fire safety, then you should choose a foam that was made using flame retardants, in the event of a fire, the material will exhibit properties like self-extinguishing.
If it is possible to use special equipment, then polyurethane foam can be used for insulation. The work will cost more if they are carried out by a team of professional builders, but the efficiency will be on top. At the first stage, the gate is measured, as well as individual sections. This will cut the material according to the parameters. The insulation is glued to the surface, and mounting foam is applied to the joints.
When the insulation of the garage door joints has been completed, you can proceed to waterproofing. To do this, use Isolon, which sometimes becomes an additional means of thermal insulation. In some cases, this material is used as the main layer of insulation.
Conclusion
Insulation of garage gapsthe gate is no less important than the thermal insulation of the canvas itself. To do this, you should use mounting foam, which has excellent adhesion with a huge amount of materials. However, before installation, the surface is moistened, because hardening occurs upon contact with moisture.
