Thatchsayf - small application in Berkshire
TAS carried out a small application of Thatchsayf Fire Retardant spray to a semi-detached cottage in Leckhampton, Berkshire.
Thatchsayf is a water-based solution containing fire retardant and intumescent ingredients for the protection of thatched roofing. This environmentally friendly solution is applied externally to the thatch surface and penetrates the stems of the thatch by up to 75mm, forming a thin protective film on the surface of the thatch stems.
A treated roof will offer protection from a number of fire risks, including sparks, ejected embers, bonfires, Chinese lanterns, fireworks and barbecues. On exposure to these risks, Thatchsayf will ‘foam up’ (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.
The application of is undertaken by our fully trained employees using specialist spraying equipment and is normally carried out between April and October. Once a roof is treated, the homeowner is issued with a Certificate of Completion, which is valid for five years after which re-application is required.
