SIGnature Air & Vapour Control Layer (Torch On) - Air & Vapour Control Layer (AVCL)
Verified by manufacturer 17 days ago
High performance Air & Vapour Control Layer as part of the SIGnature Torch On system range.
Application
Suitable for use as part of a SIGnature Torch On system Specification project.
Description
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.
Features and benefits:
- Aluminium core.
- High tensile polyester base.
- High resistance to damage and delamination.
- SBS bitumen coating low temperature flexibility -20°C.
- Prevents penetration of water vapour and damage to roof construction.
- Cold or warm roof applied options.
- CE marked.
- BBA Certificate 86/1640.
