MOY Vapobar 1 (3 mm) - Bitumen AVCL
Verified by manufacturer 2 days ago
BBA Agrément Certificate
Certificate type
Air and vapour control layer (AVCL).
Application
- Designed specifically for use as a vapour control layer in insulated warm roof systems.
- Suitable for use in buildings with high humidity conditions below.
Description
Vapobar 1 (3 mm) is an air and vapour control layer (AVCL) obtained by co-extrusion of a special steam-impermeable bitumen-polymer compound and of a reinforcement consisting of a sheet of pure aluminium and of a glass sheet. The lower face is coated with Termotene® fusible film which aids unrolling and facilitates torch bonding to various substrates. The upper face finish is finished with a sandblasting treatment.
Features and benefits:
- Suitable for use in buildings with high humidity conditions below, due to the aluminium foil lining within the membrane.
- Contain no asbestos, tar or other dangerous substances.
- Must be used with the appropriate MOY Bitumen Primer.
- Side and end joints should be appropriately lapped and torch bonded.
- Certification: BBA certified, NSAI and CE marked.
