Heat-reflective breathable membrane. Its specially designed structure reflects up to 50% of radiated heat, thus contributing up to 9% in savings on heating energy costs. It features a very high reflection coefficient, equivalent to 98%, as well as low absorption and permeability coefficients, equivalent to 2%. Compared to other conventional roof underlays, in summer months it can lower the temperature in under-roof areas by up to 5°C. It is totally water-proof and has excellent water vapor permeability properties.
All-purpose roof underlay for boarding, concrete and insulation.
Breathable, heat-reflective polyester membrane with monolith film and aluminum layer.
