Vapour control classification Sd 40

Vapour control membranes and films in this group have an Sd value of ≤ 40 m.

Products in this category, such as Eurovent® AKTIV ALU, STANDARD N, SPECIAL N and SILVER N, provide insulation against water vapour passing from inside the building towards the attic, floors or walls. They effectively prevent water vapour from migrating from the interior into the thermal insulation, providing excellent protection against moisture and condensation.

Within this group, the reflective vapour control membrane Eurovent® AKTIV ALU deserves particular attention. Its metallised layer reflects thermal radiation back into the building.
