Vapour control layer.
For internal walls, ceilings and floors.
Daltex® 146 VCL is a high resistance vapour barrier for internal walls, ceilings and floors, specifically designed to reduce the transfer of water vapour through the structure when placed on the warm side of the insulation.
Features and benefits:
Rolls should be stored flat on a clean, level surface and kept under cover.
Method of installation:
The vapour control layer should be installed as detailed in National Building Regulations. Any guidelines concerning installation that are supplied with the product should be consulted prior to laying. For general information – the vapour control layer should be positioned on the warm side of the thermal insulation.
In ceilings the product is placed between the underside of the rafters and the ceiling lining. In floors the product is placed on top of the structural decking or insulation (where present) and below any screed or sensitive floor coverings. Adjacent sheets should be lapped by 150 mm and sealed with a suitable tape. Minimise penetrations caused by services and seal all joints.
