Siltec Technical Statement - Non-Standard Details and SILTEC Warranty Cover

Flat roofs constructions, including the deck, are subject to external fire spread. When a flat roof construction is tested for its external fire performance (penetration through the roof construction and surface spread of flame), it is classified within the European system as highest BRoof(t4) through to lowest FROOF(t4).

Not all flat roofs can be classified, such as existing roofs. Some do not need to be classified due to their inherent ability to stop external fire spread, such as gravel and paving slab finished inverted roofs and protected roofs, so use is unrestricted.

With tested roofs however, Siltec are proud to have an extensive range of tested systems that can provide the highest BROOF(t4) performance classification for potentially hundreds of flat roof permutations that include single ply, liquid, hot melt, and bituminous waterproofing. This provides our clients with a full range of solutions whilst still complying with HM Government Building Regulations.
