Vapor barrier and wind protection

There is a lot of moisture in the air, which is normal. It creates a problem only when the heaters soaked under moisture lose their thermal insulation characteristics. Wet material cannot retain hot air in the room. To solve the problem, a vapor barrier will be required, which protects the insulating material from moisture. If you do not glue it tightly, this composition will get wet. For these purposes, it is necessary to ensure the tightness of the walls.

If the walls of the building are insulated with mineral materials that are in direct contact with the street. If basalt wool is used, which is a constituent element of a multi-layer wall, moisture protection is very necessary. It will also be needed when arranging frame structures, since they are also multi-layer.

It is important to reliably and competently equip the vapor barrier in frame houses. It is necessary that the membrane is mounted in the correct direction. It is important to fasten it to the racks neatly with a stapler. The joints should be oiled with mastic or glued with special tape.

If the role of insulation is played by polystyrene, eco-wool, polyurethane foam, plus ventilation works effectively in the room, then vapor barrier is not really needed.

If a barrier is needed, you will need to use one of two schemes for arranging the structure:

1. In the first case, the barrier is attached to the frame post. From above it is revetted with plasterboard or clapboard. Other wall materials that are suitable for interior decoration can also be used. This solution is suitable for buildings in which they live only seasonally, and are not used all year round. For example, this is how you can equip a guest house, cottage, workshop, parking lot. In such a situation, it is necessary to equip high-quality ventilation of the room.

2. In the second situation, a horizontal or vertical crate is arranged over the barrier. It is necessary to create a gap of 3-5 cm from the wall. The structure can be used for buildings of permanent residence, operation in the winter season. It can be installed in houses with high humidity levels.

For high-quality and reliable vapor barrier, materials are used that do not let moisture into the room. At the same time, they pass oxygen well. For the best effect, experts advise equipping a ventilation system. Together with it, the room will be reliably protected from moisture. The choice of a specific material for absorbing moisture depends on the design of the wall. Only taking this parameter into account can you determine what vapor barrier is needed at home.

Outside and inside the building, the vapor barrier is equipped in different ways. Frame structures are insulated from the inside, so the material is laid from the inside. When it comes to basement, basement floors, the vapor barrier is mounted outside. In saunas and swimming pools, this layer is equipped on both sides. The installation technology is identical to working with the basement floor.

Before starting work with the basement floor, prepare the work surface. First, it is cleaned. After that, a protective coating is applied. It is technologically more difficult to work with liquid rubber, since it requires the use of special equipment.

When using this material, the algorithm is performed:

- apply mastic, which plays the role of a primer;

- apply bituminous compositions in two layers in the format of mastic or rolls.

If the building is located above a basement or basement, moisture insulation should be provided from the inside of the room. It is important to adhere to the principles:

- the crate is mounted first, the heat insulator is placed in the second;

- cover the heat insulator with the reflective side inward, if it is present;

- it is important not to forget to glue the joints for tightness;

- finishing is done at the last stage;

- it is important not to forget to leave free space, if possible, for air circulation and elimination of steam residues

In frame houses, insulation is located in a third of all walls. Its thickness is not less than 15 cm. Therefore, you cannot do without a layer to eliminate moisture. After fixing the vapor barrier with a stapler, the joints are covered with mastic and tape.

In the case of timber buildings, insulation protects the timber. Logs are dried up to a certain stage even in the process of harvesting raw materials. However, they finally dry up in the process of using the finished home.

In the case of working with wooden buildings, vapor barriers are mounted inside or outside. In the case of external work, the insulator is laid with an overlap. At the same time, the joints are also sealed with tape. After these works, a thermal insulation layer is required. It can also be protected with waterproofing. After that - the final exterior finish.
