Air- and vapour barriers

SYSTEMATIC SAFETY AND ENERGY EFFICIENCY

CaVap Alu 1500 is a high-quality air and vapour barrier, that 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.

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

Benefits

• Easy handling
• Good vapour barrier effect
• Safe to walk on
• High fire resistance
• Highly tear resistant
• Alkali resistant
