AIRSTOP DIVA Vapour-Control Membrane

Description

The AIRSTOP DIVA vapour-control membrane is a hygrovariable membrane specially designed for airtightness. Thanks to its functional membrane, it adjusts its diffusion resistance coefficient according to ambient humidity. Ideal for new constructions and renovations, this membrane guarantees optimal management of water vapour, improving the durability of building components. Main characteristics: Sd value range: 0.5–30 m. Advantages: Hygrovariable, adapts to air humidity. Translucent to facilitate installation. Temperature resistance: From -40 to 80 °C. Weight: 86 g/m² (± 5%). Color: Translucent white with blue printing. Storage: Keep cool and dry. Application areas: Flat roofs (under specific conditions). Building components with an airtight exterior envelope (new and renovation). Technical performance: Longitudinal elongation (EN 12311-1): 68%. Transverse elongation (EN 12311-1): 79%. Longitudinal tensile strength (EN 12311-1): 180 N/50 mm. Transverse tensile strength (EN 12311-1): 125 N/50 mm. Longitudinal tear resistance (EN 12310-1): 140 N. Transverse tear resistance (EN 12310-1): 150 N.
