Application

Suitable for roof, wall and floor elements in projects of low to medium moisture classification.

Description

A 100% airtight vapour control layer with extreme variable vapour resistance which prevents structural damage and loss of insulation efficiency by adapting to moisture conditions and regulating the humidity in building elements.


Features and benefits:

  • Reduced drying out time, with additional drying capacity for unplanned humidity infiltration.
  • Extends the durability, health and longevity of buildings.
  • Greater energy efficiency and enhanced interior comfort.
  • Vapour resistance ranges from 1 MNs/g to 182 MNs/g.
  • Density of water vapour flow rate (to EN 1931): 3,16E-08 kg/(m²s).
  • Allows trapped moisture within a structure to escape.
  • CE marked to EN 13984.
  • Durable against alkali.
  • Straightness (to EN 1848-2): 75 mm/10m (maximum).
  • Joint strength (to EN 12317-2): 280 N/5cm (minimum).
  • Water column (to EN 20811): 3 m.
