This is an assessment of the Thatch Fireboard System for use in thatched roofs. The system comprises TAS100 Thatch Fireboards (8mm environmentally friendly, magnesium-oxide board) installed over the rafters prior to the installation of a traditional thatch roof covering. Thatchbatts® (noncombustible, resin bonded, mineral Rockwool slabs) are installed between the rafters and can be supported on the Thatchbatt® Wired Fixing System. A suitable vapour control layer (VCL) must be installed
according to manufacturer's instructions and, if required, a pre-determined internal finish layer.
