Your roof is a very important part of your home that plays an essential role in protecting you and
Your building may be exposed to different environmental factors in different seasons of the year
Let's face it. When moisture on the roof in contact with the heat of the sun
It is placed, it moves inward. In conventional ceilings, this moisture through
Steam is directed inside. To prevent moisture penetration into thermal insulation
It is mandatory to use a vapor barrier. Without a vapor barrier layer, moisture transferred in warm air
In the residential space inside, it may spread in thermal insulation. Also in months
In winter, when there is a possibility of condensation, rainwater may also enter the structure of the building
and cause an increase in the level of humidity in the roof. The release of water vapor in the air is possible
is lead to the formation of condensate that, in turn, may significantly on
affect the performance of the insulation layer
•
Condensation can cause great damage to the roof structure. . By creating an efficient protection, it can be ensured that the moisture in the air
It cannot enter the ceiling from living rooms and damage it. In fact, the vapor barrier layer not only prevents the penetration of moisture into the insulation
slow, but also prevents air flow through the thermally insulated roof. If the internal use of your building is wet, such as a room
Swimming pool, kitchen, shower room, etc., hot and humid air can enter through the separating walls, chimney, and electrical or plumbing holes.
The roof will open.
•
It should be noted that the use of a vapor barrier layer under all coverings of sloping roofs such as shingles, tiles, pottery, sheets, etc., to prevent
It is necessary to create condensation and improve the performance of thermal insulation and increase the lifespan of building materials.
