In simple terms, a vapour control layer is a layer on the inner face of the building which is used to reduce moisture flow into and through the walls, roof or floor. The correct use of Vapour Control Layers is one way to protect the fabric of a building and reduce the chance of damage to the insulation and timbers. Although air barrier and vapor control layers can reduce the quantity and occurrence of condensation due to both mechanisms, the use of exterior insulation (even if that insulation is a vapor barrier and/or air barrier) can warm sensitive surfaces within a wall and thereby eliminate or reduce condensation risks. As manufacturers we pass savings onto you, Phone Orders Welcome Additionally, VCLs will allow moisture that is driven towards the interior in the summer months to slowly pass back inside the building. PLASTIGUM 3 VV TF has an upper surface finished with sand/talcum and a lower surface protected by a thermofusible film. Ease and speed of installation, due to self-adhesive property of backing. as well as the installation process, play an equally important role as the vapour control layer itself.

However, you will need to test the airtightness of the OSB before using it as there is some variation in air permeability. Vapour control layers are normally considered essential under insulation in warm roof constructions to reduce the risk of condensation. NyRock Rainscreen 032 | ROCKWOOL Ltd | NBS Source This, however, can only be realistically achieved if the standard of installation is high. The notion behind a vapour control layer is to install it on the room side of the insulation so it stops the passage of warm moist air entering the structure. The damaged area may be repaired with tape, but extensive damage should be covered with an extra piece of membrane laid over the damage and sealed with tape. When talking about floors, a vapour control layer is positioned at a different level to the damp proof membrane so generally you wouldnt be able to substitute one for the other.
