COMPOSITION:

Three-layer breathable sheat; the first layer and the third layer are non-woven polypropylene fabrics with high mechanical resistance, protecting the central microporous film against foot traffic. The three layers are welded together by heat-sealing, thus obtaining a 230 g/m² vapor barrier with particularly interesting tearing strengths (>440 N/5cm long,>350 N/5cm crosswise), and therefore with mechanical characteristics that guarantee the product even in case of laying on particularly rough surfaces such as rough planks or concrete slabs.
