The garage door seal is a useful material that is used extensively for additional insulation. Most garage owners periodically face some minor miscalculations in the design of the elements. One of the most common problems is the gap in the garage door. The garage door can be sealed by yourself or by a specialist. True, the latter is not at all necessary, since all the work can be done by yourself.
What is the seal used for
The need to insulate the walls, ceiling and flooring in the garage is clear to everyone. However, some doubt that the gate should also be insulated.
Each type of gate has small slots through which cold air gets inside. This leads to a decrease in the temperature inside and an increase in humidity. To reduce heat loss, builders are advised to do the insulation of the sashes. In this case, it is necessary to sheathe not only metal structures with thermal insulation material, but also wooden ones.
Some car garage owners do not know at what stage they are engaged in insulation. All thermal insulation works are carried out during the installation of the gate.
What material should you give preference to?
The range of heaters used in a garage is quite extensive. And each of them has its own characteristics, advantages and disadvantages. For example:
- Mineral wool is durable, non-combustible, but requires the highest quality waterproofing. Otherwise, moisture will accumulate with the cotton wool, which will subsequently lead to the formation of fungus and mold.
- Available foam is available in a wide range of thicknesses to insulate a garage located in all climates. The material is not afraid of fungus, mold and rodents, does not sag over time and does not lose its insulating properties during the entire period of operation. Among the minuses is the need for crate and additional door trim.
- Reliable sprayed polyurethane is the most effective solution. For insulation, in addition to the main material, you only need a linoleum substrate and polyurethane foam. It has an increased coefficient of thermal conductivity, which favorably distinguishes the material from other methods of insulation. Among the disadvantages is the need to glue parts on which it is undesirable to apply polyurethane foam. It is best if the garage is insulated by specialists with experience in this type of work.
- Thermal insulating paint is a relatively new and expensive solution, which, nevertheless, is gaining more and more popularity. Its secret is simple. The paint is not afraid of either water or ultraviolet radiation, does not make the structure heavier, which is important both for sectional doors and for sliding mechanisms. The coating is vapor-permeable, has anti-corrosion properties, does not allow warm air to seep through the door sections to the outside.
The application of thermal insulation paint is no different from the application of any other paint and varnish material.
Additional recommendations on the choice of materials and their installation are presented in the video:
What criteria should be met
The quality of thermal insulation is influenced by the characteristics of the selected seal. Therefore, it is recommended that you familiarize yourself with the criteria that such materials must meet. These include:
- Reliability. The selected building materials must meet all approved quality standards and have a long service life.
- Tightness. The main criterion that is paid attention to when choosing thermal insulation products.Hermetic insulation has a high level of thermal insulation.
- Wear resistance. Seals made of quality material must cope with mechanical damage, high humidity and sudden changes in temperature.
- Waterproofing. Reliable heaters must have not only thermal insulation, but also waterproofing properties.
How to choose a gate seal?
Experts recommend choosing a seal depending on what type of construction the garage door has. If they are made in the presence of swinging parts, then a brush type seal will be the best option. It is impregnated with wax or other compounds and has a long service life of up to 8 years.
The presence of fixed elements in the construction of garage doors involves the use of silicone or rubber bands.
The material can be tubular or double-sided.
The rest of the gaps are sealed with any materials, which depends on the preferences of the garage owner. These can be not only factory-made materials, but also hand-made products that have elasticity and the necessary strength.
When choosing products, it is necessary to take into account their main disadvantages, since in most cases the available varieties of materials can cope well with the tasks assigned to them. They differ in the way and the degree of complexity of the device. If the safety of the material is most important to the garage owner, then it must be moisture-resistant and heat-resistant.
Various types of seals that allow you to insulate garage doors with your own hands are the main types of products. In fact, they are produced in the largest quantities and have certain advantages and disadvantages.
Classification of sealing material
To insulate the garage space, they use various heaters and therefore it is necessary to familiarize yourself in more detail with each of them. Among the common seals, the following are distinguished:
- Rubber materials. This variety is popular with car owners due to its affordable cost. Ready-made rubber plates will close the gaps through which cold air penetrates and even out the unevenness of the gate. Building materials stores sell various forms of sealant. For insulation of garage doors, a tubular or flat tape is used.
- Alkaline. Such heaters are used to cover sectional door models. Thermal insulation products of the alkaline type are impregnated with special agents that protect them from low temperature and humidity. The advantages of alkaline seals include the fact that their surface is quickly cleaned of contamination.
- Silicone. Builders consider these seals to be universal, as they are suitable for all surfaces. Silicone material is often used because it is elastic and soft. This allows you to get rid of even the smallest gaps in the gate.
- Polyurethane foam. Such heaters, like silicone, are very elastic. However, polyurethane materials are not cheap and therefore are used much less often than others.
Sealing material options
Building material on the market for closing problem areas can be divided into the following categories:
- rubber seal for garage doors, produced in the form of a tape, it can be of different shapes and colors and is sold in rolls of different lengths;
- tubular rubber - it can be of different shapes and sizes, so it is great for hiding any cracks and irregularities;
- silicone tape - in terms of its working properties, the material is close to the rubber variety, but it differs markedly in softness, more of it is needed for work;
- silicone material in the form of profiles with different shapes, is the best option for reliable filling of various gaps;
- brush seal - suitable for lazy or inexperienced craftsmen who are not able to carry out the calculations correctly or do not know how to do the job at a good level;
- a universal material with the ability to expand itself if necessary, made of polyurethane foam impregnated with acrylic.
Here are almost all the main options for seals used for garage doors. In fact, there are many more of them, and each has features in terms of working qualities, certain advantages and disadvantages. It is also proposed to choose, depending on the type of garage door:
- for opening parts, the best option is considered to be a brush seal, impregnated with wax or other compounds, it can last up to 8 years and is produced on different bases;
- it is better to equip stationary elements with a seal in the form of rubber or silicone tapes, tubular, double-sided overhead;
- other cracks can be sealed with any material that you think will be preferable.
If the owner of the garage intends to do all the work with his own hands, it is not necessary to choose a special factory-made material. Any one that combines elasticity and the required strength will do.
You should try to choose products suitable for purchase depending on personal preferences. Most of the available varieties do a good job with the required tasks and differ only in the methodology and degree of complexity of installation. Those people who highly value security should pay attention to options that have properties such as moisture resistance and heat resistance.
How to do it yourself
Some refuse to buy finished products, as they prefer to make seals on their own. However, before you carry out the insulation, you need to familiarize yourself with the recommendations for creating thermal insulation products with your own hands.
For self-production of sealing materials, they use improvised means. For example, some are made from high-strength car tires. Also, sealing strips are made from hoses that are used to water vegetables and fruits in the garden. To create a seal, it is enough to cut a few meters of the hose with a knife and align.
If you do everything right, the quality of the resulting material will be in no way inferior to the products that are sold in building materials stores.
Step-by-step installation instructions
Before insulating sectional garage doors, you need to familiarize yourself with how to do it correctly.
First, the surface of the gate is prepared. Preparatory work is carried out in several stages:
- Cleaning the surface from dirt and corrosion. In order for the thermal insulation material to tightly cover the surface, you will have to clean off all dirt and rust from it to the floor. To do this, it is better to use a grinder with a special attachment in the form of a metal brush.
- Degreasing. Finishing is carried out after preliminary degreasing of the surface with special solvents.
- Primer. Priming works are needed to protect the gate from rust. Gates made of wood are primed with linseed oil, which will prevent the appearance of mold and mildew.
After preliminary preparation of the surface, a sealant is applied at the joints of the flaps. Then the inner surface of the gate is covered with the selected seal.
To protect the seal from mechanical damage, it is covered with thick plywood or clapboard on top.
