SMARTPLY PROPASSIV Plays An Active Role In Architect's Passive House

At an architect’s new timber frame home, high racking strength and airtightness were crucial in the internal lining specification. With the installation of 240 sheets of SMARTPLY PROPASSIV (was VapAirTight), the house achieved an air change rate (n50) of 0.09 air changes per hour at 50Pa – six times better than recommended by the PassivHaus Institute. The stylish two-storey house incorporates a range of ecological materials and systems. But with large glazed areas and two cantilevers at the rear and side, the project required a structural panel that combined racking strength with exceptional airtightness – for which SMARTPLY PROPASSIV proved ideal.
