DuPont™ AirGuard® A2 FR

Surpassing the Fire Regulations

Today the fire performance of materials used in buildings is under closer scrutiny than ever before and the regulations continue to be updated. DuPont has introduced a step change in their building membranes offering: a fire retardant AVCL with European Fire Classification A2.

Membrane & Tape System – Independent Classification: A2-s1,d0

For DuPont™ AirGuard® A2 FR AVCL to provide effective airtightness and vapour control it is crucial that all laps, junctions and penetrations are sealed. In order to give assurance that a complete system is ‘fire-safe,’ a full system test, including horizontal lap sealing with Tyvek® 2060M Tape has been successfully tested according EN 13501-1 at the Prüfinstitut Hoch -> Classification Report, KB-Hoch-200148, 4th March 2020.
