Thatchsayf is a water-based solution containing fire retardant and intumescent chemicals for the protection of thatched roofing. When applied correctly, Thatchsayf penetrates the stems of the thatch by up to 75mm, forming a thin protective film on the surface of the thatch stems.
On exposure to sparks from chimneys, bonfires or barbeques, Thatchsayf will foam (intumesce) and form a carbonised char, which binds the thatch stems together, cutting off the supply of oxygen to the fire, delaying the spread of flame and lowering the radiated heat output.
Thatchsayf is a spray on fire retardant that is applied to the exterior of the thatched roof. Thatchsayf is environmentally acceptable and prevents bacterial and fungal growth.
Once applied, the roof will not need treating for five years.
What are the benefits of Thatchsayf
Thatchsayf is tested to BS476: part 3: 2004 and achieved the designation of EXT.S.BA.
The application of Thatchsayf is undertaken by TAS trained and approved contractors using a high pressure spraying system. This ensures that the correct pressure and coverage is applied to the thatch.
The homeowner or builder will be issued with a Certificate of Completion by TAS. This certificate can then be issued to Architects, Building Control Officers, Insurance Companies etc. as proof that the thatch has been correctly treated with Thatchsayf. Certification is valid for 5 years before re-application is required.
