Airtightness

AERO 3 HPV REFLEX

Flexible three-layer complex made of polypropylene, highly mechanically resistant, with polypropylene stiffener grid.

  • Micro porous, waterproof, airproof technical central membrane, with highly permeable to steam.
  • The upper side is metallized to reflect solar radiation and keep the building at comfortable temperatures in summer.
  • With double-sided adhesive tape.

Application In underlay for discontinuous roofing, to protect the roof and optimise the thermal properties of the insulation against snow run-off and wind. Installation In tensioned installation on rafters or trusses with a maximum centre distance of 90 cm, with counter-battens for strong mechanical support. The minimum size of the counter-batten is 36X20 mm. The overlap between strips is 20 cm for a roof pitch of less than 30%, otherwise 10 cm. The roof covering must be installed no later than 8 days after the installation of the under roof membrane. The integrated double-sided adhesive tape provides completely watertight and windproof bonding between two layers. The strips of adhesive tape are protected by disposable PE strips between adjacent layers, to be removed upon installation.
