Air- and vapour barriers


CaVap Eco Renova is an ecological, sd-variable vapour barrier, which has been specifically designed for all permeable insulation constructions. The functional vapour barrier consists of a four-layer, grid-strengthened composite made from bicarbonate of soda Kraft paper with a laminated, air humidity regulating functional layer. As a functional membrane with a variable sd-value, CaVap Eco Renova is the ideal interior vapour barrier for all redevelopment projects. It can be professionally applied both inside and outside of the rafters. When used on exteriors, the membrane must be protected from moisture.

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

• Roof and wall constructions
• Vapour barrier in redevelopment projects
• Timber-framed building styles
• Blow in insulation material


• Variable sd-value
• Ecological
• Good inherent stability (Kraft paper)
• Easy and secure to work with
• High tensile strength
