EPD
Certificate type
Self-adhesive SBS elastomeric bitumen air and vapour control layer (AVCL).
Application
Air and Vapour Control Layer
Description
A self-adhesive SBS elastomeric bitumen air and vapour control layer with patented “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. The product also features a tear resistant aluminium foil lining for vapour impermeability, and thermally activated bitumen stripes on its top surface to provide the bonding compound for the insulation boards.
The product benefits from cleaner, safer and faster installation than traditional torch-applied membranes.
Only to be used as part of a full Bauder Waterproofing System.
