ClassicBond Air & Vapour Control Layer (AVCL) is a self-adhesive bituminous membrane, with an aluminium foil laminate and glass fibre reinforcement.

The upper aluminium surface has a polyester coating that protects from alkalis and provides a suitable surface for polyurethane insulation adhesives to bond.

High vapour resistance enables it to be used in high-humidity environments, including swimming pools, sports halls, bathrooms and kitchens.

The AVCL is compatible with a range of common substrates including concrete, plywood, OSB, and metal decks.

ClassicBond AVCL will also withstand foot traffic during installation.

• Flame free, cold application
• Puncture resistant and foot trafficable
• self-adhesive
• High tear resistance and tensile strength
• suitable for use in high-humidity environments

AVCL Primer will improve adhesion generally, and enhance adhesion at the lower application temperature range.

It is required on all porous and vertical substrates.

5.4L tin should cover 20m2.
