Full Answer

Yes. DuoPly™ EPDM holds the British Board of Agrément certificate, No. 11/4853, issued to Flex-R Ltd. The BBA carries out assessment, testing, approval and certification of products and systems for the construction industry against national requirements, internationally recognized standards or other relevant technical specifications, reviewed and reissued every 3 years.

The fire ratings range in accordance with the build-up of the roof.

As stated in the BBA certificate No.02/3967 DuoPly® Fleece reinforced EPDM has a rating of Ext FAA as per BBA certificate. This relates to the following roof construction of steel deck, vapour barrier, PIR/PUR insulation and DuoPly® Fleece reinforced. Tested in accordance with BS476 -3

The above build up is mainly for commercial type properties so the ratings would be misguiding for domestic type buildings. In 2005 we ran further tests on typical residential style roofs and the following ratings were achieved.

Ext FAC Typical warm roof construction; OSB deck, vapour barrier, insulation and DuoPly® Fleece Reinforced
Ext FBC Typical cold roof construction; OSB deck & DuoPly® Fleece Reinforced
Test to BS476 – 3: 2004 External Fire Exposure test
