Comp-B Continuation Membrane

DESCRIPTION
Comp-B Continuation Membrane is a self-adhesive butylene sealing membrane consisting of a butyl rubber adhesive compound specially designed and developed to be classified according to BS EN 13501-1:2018. 

Comp-B 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. 

Comp-B is intended for use in the External Wall construction, as a link between the primary waterproofing system and façade 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, for example, a full-height application of PermaQuik PQ6100 Hot Melt – see illustration example below.

Features 

• Fire classified: B,s1-d0 in accordance with BS EN 13501-1:2018. 

• Tear-resistant 

• Cold applied 

• Excellent adhesion at low temperatures 

• Waterproof and self-sealing 

• Excellent heat stability 

• Resistant to ageing and to UV-rays 

• No oil migration 

• Solvent-free. 

INSTALLATION INSTRUCTIONS

• The sealing membrane must be applied to a clean, dry, smooth and dust-free surface. 

• For applications between 0°C – 5°C, ensure that frost/condensation are absent on the surface. 

• Use WebFast A2 Insulation Spray Adhesive to secure the lap joints. 

• A roller is required to apply a uniform pressure to ensure maximum bond strength.
