Fire Test puts Latest Derbigum Warm Roof Systems Through their Paces

Derbigum high performance bituminous membrane warm roof system

With recent events in the UK highlighting the requirement for compliance with up to date and relevant fire test standards, Alumasc Roofing Systems has conducted further fire tests on the Derbigum high-performance, bituminous membrane, warm roof system.

Derbigum Mineral and Derbigum Black full warm roof built-up systems, including primer, vapour barrier, adhesive, insulation, underlay and Derbigum cap sheets recently underwent testing to CEN/TS 1187:2012 – test methods for external fire exposure to roofs, and ultimately achieved the highest grade, BROOF(t4) in fire safety available in the UK, which allows unrestricted use under Building Regulations.

ENV1187 Test 4 is a test method used to determine the performance of flat roofs to external fire exposure. The two-stage test method replicates exposure to burning brands, wind and supplementary radiant heat.

Exova Warringtonfire, Gent conducted the tests in their brand-new facility in Belgium, confirming not only the applicability of original Derbigum fire rating tests, but also confirming the compliance of the current warm roof build-up using the latest BBA Certificated Derbigum system, to reflect real in-use performance.

Alumasc has already achieved top fire ratings to the previous standard (BS 476 pt3) for its products. The company has gone one step further in ascertaining the fire rating for its latest systems in anticipation of tighter regulations governing the fire resistance of construction products.

Legislation and the requirement for compliance to enter new markets have never been tougher. Alumasc aim to continue to develop and test products to ensure the highest levels of safety.
