Description

A lightweight and easy to install geotextile, which is loose laid over extruded polystyrene (XPS) insulation.


Features and benefits:

  • Waterproof.
  • Vapour permeable.
  • Contributes to the thermal improvement of the roof by retaining the water so it doesn’t penetrate to the waterproofing layer.
  • High resistance to bacteria and is resistant to UV, rot and bitumen.
