Hacierba® 1.500.90BS Energy Plus, a new cladding tray offers a high level of airtightness not previously achievable in double skin walls. This new patented product incorporates an expandable seal made from polyurethane foam, installed in the factory and protected by a peelable film.
Thanks to this new concept, the complex and time-consuming installation of a waterproofing membrane becomes unnecessary. When installing the tray on site, the peelable film is removed, and the seal will then expand gradually to provide an airtight barrier.
