Gerband Astra Phs Control Membrane, 1.5m x 50m, Sd 10m Vapour Resistance

Description

The PHS Astra Vapour Control Membrane is a membrane with an optimum fixed vapour resistance level of Sd 10m. This allows for an ideal level of vapour control, by preventing diffusion of internal vapour into the building envelope back in winter and allowing diffusion in summer. This prevents a build-up of condensed water vapour within the building envelope, which can facilitate mildew growth and constructional damage. The CE sign according to DIN 13984 gives the necessary assurance for the product's quality. It is available in a size of 1.5m x 50m.
