Garage gates are not just an entrance group, but the first line of protection of your car from uninvited guests, weather anomalies and temperature changes. Property owners often face the need to remodel or insulate the flaps, especially if the old structures are made of thin metal that does not hold heat and is easily deformed. A properly selected skin can radically change heat-insulating properties The room, turning a cold hangar into a comfortable workshop.
The process of skinning requires careful preparation and selection of quality materials, as the durability of the entire structure depends on it. Modern technologies allow the use of different types of coatings, among which the leader flooringThanks to its strength, lightness and aesthetic appearance. It is important to understand that the competent implementation of the project will not only improve the microclimate inside, but also extend the service life. metal-frameProtecting it from corrosion.
In this article, we will discuss in detail all stages of work: from the choice of insulation to the final installation of panels. You will learn what tools are needed to perform a task and how to avoid common mistakes made by beginners. Accurate compliance with technological gaps during the installation of the profile sheet prevents the deformation of the gate during the thermal expansion of the metal. Let’s start with an analysis of the available options on the market.
Choosing the optimal material for the skin
The first step in planning work is to determine the type of material that will be covered with the flaps. The construction materials market offers a wide range of solutions, each with its own advantages and disadvantages. For garage structures, resistance to mechanical damage, moisture resistance and the ability to maintain properties at low temperatures are critical.
The most popular solution remains flooring (profiled sheet). This is a steel sheet rolled through special rollers that form the ribs of stiffness. Due to the corrugated structure, it has a high bearing capacity at low weight. For garages, usually choose the brand C8, C10 or C20, where the number indicates the wave height in millimeters. A higher wave gives stiffness, but can look rough on a small gate.
Alternative metal can be a sling or OSB boardsHowever, these materials require additional treatment with antiseptics and paint coatings. The tree looks beautiful, but in the garage, where fuel vapors and humidity drops are possible, it quickly loses its properties. Metal siding is also an option, but mounting it on flat gate doors is more difficult due to the need to create an additional frame.
When choosing color and coating, you should focus on polymer protection. Coverage polyester (PE) is basic and inexpensive, but less resistant to burnout. More expensive options such as purulent (Pural) or plastisol, provide excellent protection against scratches and ultraviolet radiation. If the garage is on the sunny side, it is not recommended to save on the quality of the polymer layer.
⚠️ Note: When buying a slab, pay attention to the thickness of the metal. Sheets less than 0.45 mm thick can be easily crumpled during installation and do not provide adequate protection against hacking. The optimal thickness for garage doors is 0.5 mm.
It is also worth considering the color scheme. Dark gates (blue, green, brown) are heated more in the sun, which can lead to more intense thermal expansion of the metal and condensation inside. Light colors (white, light gray, beige) are more practical in this regard, although they require more frequent washing.
Material calculation and preparation of tools
Before proceeding with purchases, accurate measurements and calculations must be made. An error in the calculations can lead to downtime or unnecessary financial costs for the delivery of missing items. Measurements are made with roulette with an accuracy of up to a millimeter, since even a slight skew can complicate the installation.
You will need to determine the total area of the skin. The height and width of each gate is measured. If you plan to cover with overlap or overlap on the frame, a reserve of 5-10 cm on each side is added to the dimensions. Also taken into account the useful area of the sheet of profnastile, which is always less than the full width due to the overflow of waves during docking.
The following set of tools must be prepared for the work:
- 🛠️ Electrodrodell Or a screwdriver with a set of bits for screws.
- ✂️ Metal scissors for cutting the profile sheet (it is not recommended to use a Bulgarian so as not to damage the zinc layer).
- 📏 Roulette, building level and marker for marking.
- 🔨 Hammer, pliers and a set of wrenches.
- 🧤 Personal protective equipment: gloves and glasses.
Special attention should be paid to the fastening elements. For installation of profnatsil used special roofing screws with EPDM gasket And a turnkey hat or a bat. The length of the screw is selected so that it enters the metal profile of the frame by at least 20-25 mm. The use of conventional screws on metal without a rubber washer is unacceptable, as this will lead to leaks.
If you plan insulation, a knife for cutting insulation, a stapler construction and vapor insulation film are added to the list of tools. It may also be necessary to install foam to seal the gaps between the structural elements. All cutting tools should be sharpened to obtain a flat edge without burrs.
Dismantling of old coating and preparation of the frame
Preparation of the base is the foundation of a quality skin. If there is already some coating on the gate (old plywood, rusty sheet metal, paint), it must be dismantled. Often, old designs have hidden defects that appear only after the cladding is removed.
The preparation process includes several stages. First, all attachments are removed: locks, handles, valves. The old coating is then carefully removed. If nails or screws were used, they are twisted or pulled out, trying not to damage the main frame of the gate. After dismantling, the metal frame is audited.
The metal elements of the frame are cleaned of rust and old paint. This is done with a metal brush or Bulgarian with a cord brush. The surface must be cleaned to pure metal. After cleaning, the frame must be degreased and covered with a primer on rust-in. This is a critical stage, as the metal will be hidden under the new skin, and if corrosion begins there, it will be impossible to stop it.
If the geometry of the frame is broken (there are distortions, dents), they must be corrected before the installation of the skin. Curved profiles are ruled by a sledgehammer or replaced by new ones. The hinges are also checked: if the gate is skewed, the new skin may prevent them from opening or closing.
⚠️ Warning: When working with rusty metal and old paint, be sure to use a respirator and safety glasses. Fine dust and scale can seriously damage the airways and eyes.
After drying the primer, you can start installing additional elements if you need to strengthen the structure. For example, to fasten the insulation or internal lining may require the installation of horizontal or vertical jumpers from a profile pipe or wooden beam.
Technology of insulation of garage doors
Insulation of the gate is not just a desire for comfort, but a necessity for the preservation of the car and tools. The temperature in an unheated garage in winter can drop to critical values, which leads to condensation and corrosion of the car body. Well-chosen heat-insulator It creates a thermos that retains heat.
The most common materials for insulation are:
- ❄️ Mineral wool: non-combustible material with excellent sound insulation, but requires high-quality vapor insulation, as it is afraid of moisture.
- 💧 polystyrene (Foam): Lightweight, moisture resistant, cheap, but combustible and can crumble over time.
- 🚀 Extruded polystyrene foam (Penoplex): stronger foam, does not absorb water, has low thermal conductivity, but more expensive.
- 🌬️ polyurethane: sprayed, fills all the cracks, but requires special equipment for application.
Installation of the insulation is made in cells formed by the frame of the gate. If a plate material (foam, minwat) is used, it is cut into the size of cells with a small margin (1-2 cm) to ensure a tight fit without gaps. Fixing is carried out using mounting foam or special glue. It is important to fill all the voids, as even small cracks will become bridges of cold.
After laying the insulation, it is necessary to close it with a vapor insulation film. It protects the material from moisture that can penetrate from inside the room (especially if the garage is drying things or a wet car). The film is attached by a construction stapler to the frame with a swath of stripes of 10-15 cm. The joints of the film are necessarily glued with special tape.
Do I need vapor insulation when using Penoplex?
The foam does not absorb moisture, so technically vapor insulation is not necessary for it. However, the creation of a closed circuit with vapor insulation protects the metal frame of the gate itself from condensation formed on the inner surface of the metal at a temperature difference.
To achieve maximum effect, materials can be combined. For example, use foil foil foil on top of the main layer of the insulation. It will reflect the thermal radiation back into the room. The foil layer should look inside the garage.
Step-by-step instruction for installation of profnatsil
Installation of the flooring on the prepared and insulated frame is the final stage of work. The quality of this stage depends on the appearance of the gate and their tightness. Work is better to carry out together, as the sheets have sailing and can be inconvenient for installation alone, especially in windy weather.
The installation process is as follows:
- Open the sheets: The flooring is cut with scissors on metal strictly according to marking. Cut across the waves, starting at the edge. Bulgarian can not be used, as sparks burn out zinc and polymer, leaving a focus of future rust.
- Markings and start sheet: Installation starts from the bottom or from the corner, depending on the design. The first sheet is leveled. It is important to set the right vertical immediately, otherwise the whole row will go crooked.
- Fixing: The sheet is pressed against the frame and fixed by screws. The fastener is screwed into the lower part of the wave (trench), where the metal is adjacent to the frame. The screws are twisted perpendicularly to the surface. You can not pull a screw - this will crush the EPDM gasket, not twist too - there will be no tightness.
- Docking: The next page is laid over one wave of the previous one. The coating ensures the tightness of the connection and hides the fastener.
The step of attaching screws is usually one wave in the horizontal row and after 30-40 cm in the vertical. In areas of increased wind load (gate edge), the mounting step can be reduced. All sections of sheets, especially if they fell on the installation site of locks or wickets, it is necessary to paint a special repair enamel in the color of profnatsil.
☑️ Checklist before screwing
Pay special attention to the places around the locks and handles. It may require a complicated cutout. It is better to mark the cutouts on a separate piece of cardboard, attach it to the gate, make sure of accuracy, and only then transfer the marking to the metal. Cut holes better with hewn scissors or a metal drill with a diameter of 10-12 mm along the contour, then gently knocking out the jumpers.
Comparison of characteristics of materials for skinning
To finally decide on the choice of material, it is useful to compare their key characteristics in the table. This will help to weigh all the pros and cons in terms of cost, durability and complexity of installation.
| Characteristics | Flooring (0.5 mm) | Wooden wagon | OSB plate (12 mm) |
|---|---|---|---|
| Term of service | 20-40 years | 5-10 years (without care) | 10-15 years |
| Wet resistance | Tall. | Low (requires processing) | Medium (fears of direct water intake) |
| Fire safety | Non-flammable | Fuel | Fuel |
| Difficulty of installation | Low. | Medium | Low. |
| Aesthetics | Modern, strict. | Classic, "warm" | Technical, requires painting |
As can be seen from the table, flooring wins in most parameters, especially in a garage, where fire safety and resistance to the external environment are important. Wooden trimming may be appropriate if the garage is built into a wooden house or is part of a bath to keep a uniform style.
OSB boards are often chosen as a temporary or budgetary solution. They are easy to install, but over time they can be layered from moisture. If you choose OSB, be sure to use class plates. OSB-3 (moisture-resistant) and provide high-quality exterior finishes, for example, siding or painting rubber paint.
⚠️ Attention: When installing the flooring in hot weather, the metal is very heated. Work with gloves to avoid burns, and try not to rely on the sharp edges of the sheets.
Use a magnetic holder for the bit on a screwdriver - this will speed up the work, since you need to hold the sheet with one hand and work with the other tool.
Finishing and gate care
After the installation of the sheathing, the gates become finished, but the work is not yet finished. It is necessary to install additional elements: skates, corner bars, end plugs. They not only decorate the structure, but also protect the joints from water leakage and dust.
Pay special attention to the perimeter seal. On the contour of the gate, in the places where the flaps adjoin the frame of the garage, it is recommended to fix a rubber seal or brush profile. This will prevent snow from blowing and getting inside. The gap between the flaps can also be closed with a special flybar.
Care for new gates is minimal, but necessary to preserve their appearance. Once a year, it is recommended to wash the dirt with water with the addition of a soft detergent. Do not use abrasive powders or solvents that may damage the polymer coating. If scratches appear on the surface, they should be painted immediately to prevent corrosion.
Checking of the fastener is carried out six months after installation. The metal can shrink or have a temperature strain, so some screws can weaken. They just need to be tightened. Regular lubrication of hinges and locks will also prolong the life of the entire structure.
High-quality sheathing of the gate with insulation reduces heat loss of the garage to 30% and significantly prolongs the life of the car, preventing the formation of condensation.
Frequently Asked Questions (FAQ)
Can I put a stain on the door without a stain?
Yes, you can. If the garage is not heated and is used only as a parking lot, insulation is not mandatory. However, even a layer of foam 3-5 cm thick will significantly reduce the formation of condensate, which is the main enemy of the metal and the car body.
What thickness of flooring to choose for the garage?
The optimal thickness of the metal is 0.5 mm. The sheets of 0.4 mm are too thin and easily crumpled, and 0.6-0.7 mm are more expensive and heavier, which creates an extra load on the hinges, without giving significant advantages to the vertical surface of the gate.
Do I need to lay the frame if it is already painted?
If the old paint is held firmly, not swelled and does not rust under it, it is enough to degrease the surface. If there is even the slightest doubt or traces of rust, it is better to clean to metal and primed again, since under a new skin the process of rotting will accelerate due to lack of ventilation.
How to cut the flooring properly so that it does not rust?
Use only metal scissors (manual or electric) or hewn scissors. Bulgarian (USM) with abrasive circle burns zinc coating and polymer layer on the edge of the cut due to the high temperature, which is guaranteed to lead to corrosion in this place in 1-2 years.
