What is a Vapour Control Layer (VCL)? 

A vapour control layer (VCL), also known as a vapour barrier, is a material used in building construction to prevent the passage of water vapour through walls, ceilings, floors, or roofs. It is typically installed on the “warm” side of the insulation (typically the interior side) where it helps to control moisture levels within the building envelope. By blocking the movement of water vapour, a VCL helps to prevent condensation from occurring within the building structure, which can lead to issues such as mould growth, rot, and reduced insulation effectiveness.

What is a Radiant Barrier?

A radiant barrier is a type of material designed to reduce radiant heat transfer. Radiant barriers work by reflecting radiant heat away from the surface they cover, which helps to keep spaces cooler in the summer and warmer in the winter. They are often installed in attics, under roofs, or in walls where they can block the transfer of radiant heat from the sun or from indoor heating systems. By minimising radiant heat transfer, radiant barriers can help improve energy efficiency and increase comfort levels within buildings.

How to install SuperFOIL SFTV?

A vapour control layer should be applied on the interior side of any wall, roof or flooring, over timber studs before the internal lining. It should be 100% sealed to the structure with double-sided butyl tapes, pre-applied to all areas where a fixing is to be made, and finished with metallised tapes to ensure a complete vapour seal.
