Walki®Wall Breath, medium weight

This LCA covers the Walki®Wall Breath -family wind barriers manufactured by Walki Group Oy factories in Valkeakoski, Finland and Pietarsaari, Finland.

Walki®Wall Breath -family wind barriers are used for the protection of facades against wind, rain and moisture. They are applied in case of facade insulation systems. These wind barriers are age-resistant with a diffusion-open polymer barrier protected by two non-woven polypropylene (PP) non-woven fabrics. The special polymer barrier of the products ensures very good diffusion-open properties that allow moisture and vapour to migrate out of the structure.

These products are manufactured with coextrusion laminating.
