Solutions and products - Residential construction - Aspira membranes
New Aspira 3-layer roof membranes ensure respiration of a roof slope, so important to the condition of the whole house. The roof respires so easily and removes all dampness collected inside of the thermal insulation, and it is protected against the outside water. Aspira membranes are waterproof and highly vapour permeable, and three polypropylene layers guarantee high resistance to stretching and tensile strength.
Aspira Standard, Aspira Plus and Aspira Max membranes can be used under any roof covering, They also constitute extra thermal insulation which reduce heat losses in a building.
Aspira Plus is particularly recommended for roofs covered with metal roofing tiles – combination of high resistance with excellent vapour permeability qualities ensures protection and proper air ventilation of steep-sloped roofs.
ASPIRA Max performs best in the most difficult conditions – this membrane, because of its parameters, can be classified as a roof screen type. Apart from its vapour permeability it is resistant no only to mechanical forces but also to UV radiation. The most resistant ASPIRA Max is recommended for full roof boarding.
ASPIRA Membrane is the best alterative for roofing paper. It protects the roof even up to 4 months before the proper roof coverage is placed. It ensures high comfort because it blocks unpleasant smell of tarry substances during sunny days.
ASPIRA Standard is a product which combines high quality and low price. It is distinguished by good vapour permeability parameters and good resistance.
The use of roof membranes extends the endurance of a roof slope, increases the building protection and thermal insulation rating. All ASPIRA membranes are of 3-layer type.
