The highly breathable reflective membrane TRASPIR ALU 200 is ideal for installation on both the exterior and interior sides of the roof. It optimizes the windproofing of the construction, protecting it from the entry of warm air in summer and cold air in winter. Durable due to its high mass per unit area, it is equipped with a double integrated tape.

TRASPIR ALU 200 is a highly breathable membrane that reflects heat. Reflective membranes on the exterior side offer an advantage during the hot season by reflecting heat outwards. The high mass per unit area ensures resistance to abrasion and walking, while the double integrated tape simplifies installation and ensures professional sealing.

Technical data: Mass per unit area 200 g/m², thickness 0.8 mm, vapor transmission (Sd) 0.045 m, tensile strength MD/CD 350/225 N/50 mm, elongation MD/CD 5/4%, tear resistance 200/200 N, waterproofness class W1, reaction to fire class E, temperature resistance -40 / +80 °C, air permeability <0.02 m³/(m²·h·50Pa), thermal conductivity 0.3 W/(m·K), specific heat 1800 J/(kg·K), density approximately 250 kg/m³, vapor resistance factor approximately 60, UV stability 336 hours (3 months), waterproofness after artificial aging class W1, flexibility at low temperatures -30 °C, equivalent thermal resistance with 50 mm air gap 0.821/0.731 (m²·K)/W.

Composition: coating of perforated aluminum membrane, reinforcing mesh PL, top layer of non-woven PP fabric, middle layer of breathable PL membrane, bottom layer of non-woven PP fabric.

TRASPIR ALU 200 also provides shielding from electromagnetic waves, with a measured value above 20 dB and shielding effectiveness greater than 99%. Installation is done by unrolling the membrane, gradually removing the release film, and pressing for proper adhesion. Overlaps must be at least 15 cm to ensure waterproofness.
