Air- and vapour barriers

SYSTEMATIC SAFETY AND ENERGY EFFICIENCY

CaVap 2 SK is an all-round vapour barrier for all ventilated and unventilated, diffusion permeable roof and wall constructions. The vapour barrier consists of a polypropylene non-woven fibre with a copolymer coating. The membrane is equipped with an integrated selfadhesive tape, which is used as a processing aid. Also available without self-adhesive strips as CaVap 2. CaVap 2 SK is translucent and thus allows the rafters behind the vapour barrier to remain visible. Thanks to its high flexibility, CaVap 2 SK can also easily adjust to complex details.

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 for internal construction
• Vapour barrier for external renovations
• Ventilated roof constructions
• Unventilated, wall and roof constructions which are open to diffusion
• Timber-framed building styles
• Renovation work and new constructions

Benefits

• Multi-use vapour barrier
• Good inherent stability through reinforced non-woven fibre
• Translucent (rafters are visible)
• Very high anti-tear values
• Easy and secure working
• Alkali resistant
