ITP FlameOUT® Block Class A is a limited-combustible Euroclass A2-s1,d0 rated air and vapour control layer (AVCL) Independently tested to EN-13501-1. ITP FlameOUT® Block Class A is especially suited to both high rise, 18 m+ in England and 11 m+ in Scotland and safety critical builds.

When used within wall and roof installations ITP FlameOUT® Block Class A prevents moisture within the building's warm air from reaching the insulation layer and forming interstitial condensation.

ITP FlameOUT® Block Class A has a glass reinforcement scrim which provides excellent tensile strength in wall and roof installations. The aluminium layer has a special protection coating to protect the aluminium layer from corrosion.

ITP FlameOUT® Block Class A contributes to both BS 9250 for the airtightness in ‘a well-sealed ceiling’ and BS 5250 aiding the control of condensation within a roof space.

Can be used in conjunction with Safe One® A2 breather membrane or Stamisol A1® breather membrane which are installed on the cold side of the building envelope.
