Vapour control classification Sd 20

Vapour control membranes in this category have an Sd value of ≤ 18 m.

Products in this category, such as Eurovent® CLIMA X20, incorporate a special vapour control functional film that protects against uncontrolled water vapour flow. They act as a barrier to water vapour passing from inside the building towards the attic, floors or walls.

They provide excellent protection for thermal insulation against water vapour condensation while allowing controlled water vapour migration. This prevents moisture problems and eliminates the so-called plastic bag effect.

Within this group, the reinforced vapour control membrane Eurovent® CLIMA X20 deserves particular attention thanks to its exceptional mechanical strength in its class. It is designed for frame construction combined with blown-in thermal insulation, such as blown cellulose. It is also suitable for prefabricated, modular and passive construction.
