The aim of THATCH-SAFE® was to provide a one product solution for fire barrier and insulation requirements for new thatched buildings which also addressed:
1 Heat transfer from chimney to thatch.
THATCH-SAFE® is designed to be wrapped around the chimney under theThatch as a simple and cost effective solution to the No 1 known cause ofThatched roof fires.
2 Longevity of the thatched roof - should it not catch fire THATCH-SAFE® is proven to be truly micro-porous so the roof can breathe. This maximises the lifespan of the thatched roof.
THATCH-SAFE® and the Dorset Model
THATCH-SAFE® has been developed to meet the same criteria as The Dorset Model ie B4 Building Regulations
Plus it has insulation - so that with 400mm of Water Reed it meets 0.2 µ value.
Regulation B4 requires that the roof of a building shall offer adequate resistance to the spread of fire over the roof and from one building to another, having regard to the use and position of the building.
Thatched buildings generally should be at least 12m from a boundary except that separating semi-detached houses. Small (3m2) thatched extensions may be as near as 6m to a boundary.
Requirements
Rafters to be overdrawn with minimum 30 minute water-resisting fire barrier and
50 x 25mm counter battens are recommended on a micro-porous sheet.
THATCH-SAFE® is not just designed for new thatched roofs. It is flexible so not limited to regularly shaped roofs, hence it is also used on older thatched properties whose roofs are more undulating.
