PHS Astra vapour control membrane enables airtightness and vapour control in roof and wall constructions. It has 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 and prevents a build-up of condensation within the building envelope, which can cause mildew growth and structural damage. The CE sign in accordance with DIN 13984 gives the necessary assurance for the quality of the product.
Applications:
- Interior installation to create an airtight envelope.
- All construction types.
- Ceilings, walls, floors and loft spaces.
Features & Benefits:
- Lightweight, flexible and moisture resistant.
- Improves airtightness and thermal performance.
- Increases building energy efficiency.
- Water vapour transmission fixed Sd value 10m.
- Reduces draughts and heat loss.
