High performance Air and Vapour Control Layer as part of the SIGnature Torch On system range.
Suitable for use as part of a SIGnature Torch On system Specification project.
SIGnature Air & Vapour Control Layer (Torch On) is a high performance air vapour control layer for use in the SIGnature Torch On system range.
It comprises an aluminium core, reinforced with polyester and coated with a quick melt SBS modified bitumen. The lower surface has a sacrificial film which rapidly melts during the torching operation.
The air & vapour control layer is bonded to the top of the structural deck prior to the bonding of the insulation layer in warm flat roof construction.
