About the material
Protecting the structure throughout its service life
The three-layer material combines polypropylene nonwoven fabric with two polymer films.
It protects insulation and structures from indoor water vapour and air movement while limiting the release of insulation fibres into the building.
Applications
- 01Insulated pitched roofs
- 02Flat roofs
- 03Timber-frame walls
- 04Internal partitions
- 05Attic, intermediate and basement floors
- 06Floors on concrete bases
