Butyl Tape BB
ME480 is a membrane on a roll with fire classification B-s1, d0 to EN13501-1, composed of a laminate film with a layer of modified butyl rubber adhesive, aluminium foil finish and a siliconised release liner.
ME480 has been specifically designed for construction applications where high fire retardent performance is required (e.g. tall buildings - Relevant Buildings >18 m high).
Provides permanent watertightness, air tightness, compartmentalization and for repairs of vapour-impermeable joints and seals in construction applications.
Bonds with most normal building materials such as glass, steel, concrete, stone, wood and aluminium.
- Reaction to fire - EN13501-1: Class B-s1, d0 (Complies with ADB requirements)
- Both the aluminium foil and the butyl adhesive layer are UV-resistant
- Adhesive layer remains flexible at high and extremely low temperatures
- Adhesive layer does not dry out
- Bonds to virtually all common substrates
- Very high vapour resistance, including water and airtightness
