The reason for using vapor barrier in Shibra roof

Your roof is a very important part of your home that plays an essential role in protecting you and your building from the different environmental factors that we may encounter in different seasons of the year. When the moisture on the roof comes in contact with the heat of the sun, it moves inward. In conventional ceilings, this moisture is directed inside through steam. To prevent the penetration of moisture into thermal insulation, use A vapor barrier is required. Without a vapor barrier layer, moisture carried in the warm air inside the living space may diffuse into the thermal insulation. Also, in the winter months when there is a possibility of condensation, rainwater may also be used enter the building fabric and cause an increase in the moisture level in the roof. The release of water vapor in the air may lead to the formation of condensate, which, in turn, may significantly affect the performance of the insulation layer. Furthermore Condensation may cause great damage to the roof structure. . By creating an efficient protection, it can be ensured that the moisture in the air from the living rooms cannot enter the ceiling and damage it. In fact, the vapor barrier layer is not It not only prevents the penetration of moisture into the insulation, but also prevents the flow of air through the thermally insulated roof. Also, if the internal use of your building is humid, such as the pool room, kitchen, shower room, etc., hot and humid air can enter the ceiling through the separating walls, chimney, and electrical or plumbing holes. It should be noted that when constructing roofs made with asphalt shingles in hot and humid climates, a vapor barrier must be installed between the shingles and the roof deck (osb wood) because the shingles, water from condensation caused by cooling They store air and rain. Prevent the movement of water vapor inside the roof system by using a vapor barrier layer.
