Halley Alu Vap -25°C self-adhesive membrane offers the combination of several particularities: high flexibility at low temperature, high adhesion to the support without the aid of flames and vapour screen function. It is very useful in application contexts where the risk of fire is very high.
HALLEY ALU VAP self-adhesive bituminous membrane is made with two different types of compound: the external face is made of APP -25°C elastoplastomeric compound. The internal face and the overlap side are made of -25°C elastomeric self-adhesive compound by simple pressure.
The excellent quality of this membrane is highlighted in particular by two indicators: flexibility at low temperature (-25°C) and adhesion to the various supports. The excellent adhesiveness makes it easy to adapt when laying in areas with a warm temperate climate. The excellent flexibility, with the use of hot air, allows easy application even in cold climate areas.
The reinforcement used in the HALLEY ALU VAP membrane consists of an aluminum foil coupled with polyester which guarantees absolute impermeability to water vapour.
This feature allows to safeguard the effectiveness of the insulation by preventing the passage of vapour from the internal environment to the insulating material.
