Advantages

  • High water vapour permeability due to which the membrane absorbs moisture and directs it outside through the ventilation gap.
  • Completely watertight, protects the thermal insulation from the outside against rain or snow.
  • It has UV stabilizers, slowing down the aging process, caused by weather conditions.

Usage

  • It is a diffusion-open membrane, designed as a layer of preliminary covering for the external roofing.
  • It is also an excellent windproof material, intended for walls of buildings in skeletal structures.
  • Due to the low Sd coefficient, it is used in roofs with thermal insulation up to the full rafter height, in which it is laid directly on the insulation.
