Membranes with high vapour permeability

The EUROTOP membranes are characterised by a unique combination of such parameters as
watertightness and water vapour diffusivity. High watertightness protects the roof structure from:

• seepage and water condensation
• under roofing
• wind driven precipitation

High water vapour permeability offered by the EUROTOP membrane allows 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 sarking with turquoise printed side facing outwards.
