AirGap Extend

Moisture-protective air gap board made of special corrugated material with wind-protective properties for insulation in roof structures. The board is diffusion-open, moisture-repellent, and equipped with spacers that ensure the ventilation gap in parallel roofs or cold attics. The air gap board is part of a system with the product wind deflector, where both products can be used together or alternatively only the wind deflector. It is the design of the roof structure that determines

Application Area

The product is used as an external climate screen as a continuation after the wind deflector, and in cooperation with each other, a longer ventilation gap can be created for, for example, parallel roofs.

For low-sloped roofs, less than 14° (1:4), the board with a 50 mm distance is recommended.

Installation

The air gap board is mounted directly against the roof underlay. The fastening is done between the rafters/roof beams and with corrosion-protected staples (140/10) or roofing nails (min dim 25 x 2.5mm). See installation instructions for details

Important!

  • Fasteners (mechanical attachment) should be galvanized corrosion-protected staples (140/10) or roofing nails at least 25 x 2.5 mm.
  • For optimal air tightness, the joints are taped in overlap with Sealing Tape T-Flex.
  • Storage and warehousing should always be protected from precipitation.
  • The air gap boards are moisture-repellent, but precipitation and adverse weather conditions during and after installation should be avoided.
