Membranes with high vapour permability
The EUROTOP membranes feature a unique combination of such parameters as watertightness and water vapour diffusivity. High watertightness protects the roof structure and insulation from:
- leakages and water condensation under the roofing
- precipitation which is wind-driven under the primary roofing
High water vapour permeability offered by the EUROTOP membrane enables moving insulation towards the membrane surface without the need for any ventilation gaps in the roof or wall structures. This makes it possible to apply thicker layer of insulation which translates into energy savings. The EUROTOP membrane is laid directly onto rafters, insulation or boarding with turquoise printed side facing outwards.
