Technical data: with a water vapour permeability of 0.04 m and a weight of approx. 200 g/m² Hausa Titanium HU200SK offers technical efficiency and aesthetic flexibility. It complies with fire protection class E and offers a water permeability of W1. The UV resistance is 3 months and the mechanical properties in longitudinal and transverse directions are impressive.
Product features: made from three layers of polypropylene fleece and an innovative functional film, the Hausa Titanium HU200SK track offers an optimal combination of water vapour permeability and waterproofing. The special anti-reflective coating minimises the negative effects of light reflections, while UV stabilisers slow down the ageing process of the membrane and thus ensure the longevity of the product.
Our product: Hausa Titanium HU200SK underlay sheet sets new standards in roofing technology. This highly flexible, four-layer web is characterised by its exceptional diffusion capacity (SD value 0.04 m) and robustness. It is not only tear-resistant and weather-resistant, but also completely waterproof, making it the ideal choice for any type of roofing. The Titanium HU200SK underlay sheet is recommended for use in roof constructions with solar panels.
Contents: 1 x 75 m². Each roll of Hausa Titanium HU200SK is 1.5 m wide and 50 m long, which corresponds to an area of 75 m², with a surface weight of 200 g/m²; with 2 adhesive strips.
APPLICATION: The versatility of the Hausa Titanium HU200SK makes it the perfect solution for ventilated and unventilated roofs. Whether on ceramic, concrete, clay or sheet roofs, the sheet can be laid directly on the thermal insulation or wooden construction without the need for a ventilation gap. Its light weight makes it easier to use and lay and increases work safety on the roof.
