Air- and vapour barriers

SYSTEMATIC SAFETY AND ENERGY EFFICIENCY

CaVap Alu 1500 SK is a high-quality air and vapour barrier, which has been specially designed for flat, inclined roof areas. The vapour barrier consists of a multilayer aluminium composite, with an extremely tear-resistant fabric reinforcement. The membrane is equipped on its underside with an all-over acrylic adhesive, that is covered by a robust, siliconized polyethylene liner.

When working with the material it is necessary to observe the applicable standards, the generally recognized rules of manufacturers as well as the CaPlast laying information. Subject to technical modifications.



Fields of application

• Vapour barrier with an sd value of > 1.500 m
• For flat, inclined roof areas such as industrial halls etc.
• Especially suitable for use with trapezoid sheet substrates
• Suitable for mechanical fixation and under load

Benefits

• With an all - over acrylic adhesive
• Easy handling
• Good vapour barrier effect
• Safe to walk on
• High fire resistance
• Highly tear resistant
• Alkali resistant
