Comp-B Continuation Membrane and WebFast A2 Adhesive - Self-adhesive Continuation Membrane
Verified by manufacturer 3 months ago
Comp-B Continuation Membrane is a self-adhesive butylene membrane consisting of a butyl rubber adhesive compound specially designed and developed to be classified according to BS EN 13501-1:2018.
Application
Intended for use in the External Wall construction, as a link between the primary waterproofing system and facade DPM to create a weathertight seal for the whole building envelope.
The limited-combustibility rating of Comp-B ensures compliance for use in locations where other membranes may not be practical to install.
Description
Comp-B Continuation Membrane is a self-adhesive butylene membrane consisting of a butyl rubber adhesive compound specially designed and developed to be classified according to BS EN 13501-1:2018.
Comp-B Self-Adhesive Continuation Membrane is protected by a reinforced aluminium film and is resistant to ageing and UV-rays. It is highly adhesive, even at low temperatures, to all common building materials. It has been designed for the construction field, in particular, for those building where high performances, in terms of reaction to fire, are needed.
Features and benefits:
- Fire classified: B,s1-d0 in accordance with BS EN 13501-1:2018.
- Tear-resistant.
- Cold applied.
- Excellent adhesion at low temperatures.
- Waterproof.
- Excellent heat stability.
- Resistant to ageing and to UV-rays.
- No oil migration.
- Solvent-free.
