Fire protection systems
for thatched roofs.
We install a range of proven fire protection systems designed to improve the fire resistance of thatched roofs, in line with current Building Control guidance and industry best practice.
The right solution will depend on the property, roof construction, and whether the work forms part of a new build, re-thatch, or repair. Our approach is to specify the most appropriate system for each project, ensuring effective protection without compromising the performance or breathability of the roof.
In the event of a fire, the outer thatch layer is typically considered sacrificial. The purpose of these systems is to help protect the structure beneath and slow the spread of fire, providing valuable time and reducing risk to the property.
Thatch Firewall (LFB60)
