PHS Apollo Vapour Control Membrane enables airtightness and vapour control in roof and wall constructions.
PHS Apollo Vapour Control Membrane is a 3m membrane, with an optimum fixed vapour resistance level of Sd 2m. 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, that facilitates mildew growth and constructional damage.
The CE sign according to DIN 13984 gives the necessary assurance for the quality of the product.
