• 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.
  • Every layer have UV stabilizers, slowing down the aging process, caused by weather conditions.
  • Thanks to its high basis weight, it has a high resistance to mechanical damage that may occur during application work.


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