SAFE ONE, the UK’s first non-combustible breather membrane, is offered by Industrial Textiles & Plastics (ITP). Suitable for both wall and roof installations, Safe One is a woven material,  engineered to be rated non-combustible according to the highest level of UK and European standards. Independently tested to EN 13501-1, Safe One is rated A2-s1,d0. Prior to the launch of this innovative multipurpose breather membrane, the highest level of flame retardant breather materials offered in the UK were Class 0 (BS 476 Parts 6 & 7) or Euroclass B.

The introduction of Safe One is timely: changes to UK building regulations have banned the use of combustible materials on the external walls of new buildings over 18 metres that contain flats, plus new hospitals, residential care properties and dormitories in schools and student accommodation. “Safe One represents a new generation of fire protection materials for the construction industry,” said ITP’s Managing Director, Marc van der Voort.

While the Euroclass B rating is the highest for flammable materials, Class A2 rated materials are non-combustible. The S1 rating indicates very limited smoke development while the d0 rating shows no burning droplets when the material is exposed to direct flame during the testing process.

CE Certified Safe One is heavyweight with very high tensile strength, good water vapour transmission and is rated W1 for water tightness. Proprietary FR tapes and glues are offered with the membrane for effective installation.

Safe One complements the ITP’s FlameOut range of flame retardant membranes: FlameOut Breathe (rated Class B-s1,d0), a W1 breather membrane,  and FlameOut Block and FlameOut Block Plus, flame retardant vapour control layers (VCLs) both rated Class B-s1,d0. ITP also offers UV resistant breather membranes, which are suitable for use behind open or closed ventilated rainscreens and facades: Powerlon UV145FR (Class B-s3,d0) and Powerlon UV Colour FR (Class B-s2,d0).
