Air- and vapour barriers


CaVap Eco 5 is an ecological barrier to air and vapour that has been specifically developed for all insulation constructions which are open to diffusion. The vapour barrier consists of an innovative, multi-layer composite material made from soda kraft paper with anti-tear, grid reinforcement. The high anti-tear values ensure practical laying and laying which, with the simplest of means, is fast. The product is especially suited to regulating moisture in the wall areas of timber-framed buildings and in ready-built construction elements. This vapour barrier should not be permanently exposed to 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
• Ventilated and unventilated systems
• Timber-framed building styles
• Suitable for blown insulation


• Ecological
• Good inherent stability
• Easy and secure working
• High anti-tear values
