PHS Sd2 Vapour Control Membrane enables airtightness and vapour control in roof and wall connections.
PHS Sd2 Vapour Control Membrane has an optimum fixed vapour resistance level of Sd 2m. This allows for an ideal level of vapour control by preventing diffusion of internal humidity into the building envelope in winter and allowing back fusion from the building envelope in summer. This prevents a build-up of condensed water vapour within the construction that facilitates mildew growth and constructional damage.
The CE sign according to DIN EN 13984 gives the necessary assurance for the quality of the product.
