With access to a wide range of drainage products in our portfolio, green roof systems can be tailored for each specific project but are essentially based around 3 key types
Siltec green roofing systems offer many benefits, including:
Increased mass of a green roof system improves sound absorption.
Water run off to storm drains is reduced due to the absorpsion of water within the green roofing substrate. In addition, run off is delayed whilst it filters through the system at roof level, reducing the impact during heavy precipitation to the drainage network.
The Siltec green roof systems offer beneficial temperature moderation in two ways. First, they keep the waterproofing system below at a more average temperature and fully protected from exposed weather extremes, thus further extending the lifespan of the waterproofing. Secondly, the vegetation barrier reduces heat gain and loss within the building, improving its comfort for occupants and reducing both energy costs and C02 emissions over the lifetime of the building.

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.
