CA Building Products over the last fifteen years has developed roof and wall cladding systems to comply with the onerous demands of building regulations in terms of thermal performance, air leakage, acoustics, etc., however, we feel the most critical demand under building regulations is Approved Document B: Fire safety – Volume 2 Buildings Other Than Dwellings.
At CA we have conducted extensive testing and development in order to achieve the best possible fire performance for metal clad buildings. We design all our systems with fire performance as one of the most fundamental factors, by adopting non-combustible materials, such as our Therma-quilt insulant, which has been tested by Loss Prevention Certification Board (LPCB) to BS 476: Part 4: 1970, and achieved a ‘non-combustible’ classification.
In March 2002, CA were the first twin skin manufacturer to gain LPCB approval to the widely known and widely understood wall and ceiling test LPS 1181, for our Twin-Therm® built up roof and wall cladding system achieving Grade EXT-B for the standard Twin-Therm® roof and wall system and Grade EXT-A30 for the Twin-Therm® FireWall system.
CA has a proud tradition of innovation, which has seen several FireWall systems either tested or assessed by the UK’s leading authority; Warrington Fire.
Warrington Fire has either tested or assessed a number of FireWall systems from CA Building Products which have achieved the following performances;
- 240 minutes integrity &:÷ 30 minutes insulation (LPCB EXT-A30)
- 240 minutes integrity &:÷ 15 minutes insulation (LPCB EXT-A15)
- 60 minutes integrity only (LPCB EXT-B)
Depending on your project specific requirements, you may require one or all of these systems. To save confusion click here to contact CA Building Product’s technical team for assistance.
