totally refurbished buildings where the roof timbers are straight enough to take a rigid board. When used with our Thatchbatt® as part of a system, the fireboard will meet the criteria of the ‘Dorset Model’. The TAS firewall membranes are normally used on existing roofs that are not straight enough to accept the rigid fireboard system. Archetech - Page 144 Our high density non-combustible Thatchbatts® are designed to be friction fitted between the roof timbers, which will give greater protection by reducing the thermal transfer around the roof timbers reducing the risk of secondary fires starting and potential roof collapse. Modern living under thatch has dramatically changed with the introduction of modern central heating, double glazing, power showers and many more people wanting fully vaulted ceilings. Additionally the requirements and associated recommendations from Building Control and insurance companies see the requirement for fire barriers and increased levels of insulation to be installed within the roof structure. It is widely accepted in the construction industry that in addition to sufficient levels of insulation, vapour control layers are required to control vapour and reduce the risk of condensation. There are many vapour control products available, however, it is important to install the correct product that best suits each individual building. Summary Prevention is the best solution. In the event of a fire, a physical fire barrier or system will buy crucial time, dramatically help reduce the amount of damage and also create a safer working environment for Fire & Rescue Services.
