VAPOR BARRIER

Steep roofs mostly demand the building in of a vapor barrier. It is mostly a special foil that repels moisture and it is vapor permeable from beneath. The closed cell structure of PU- spot-foam enables a continuous surface that meets these demands outstandingly. This structure functions as a vapor barrier, too. You can renounce an additional barrier installation.

If there is no vapor pressure, the insulation won’t have any moisture content.
