Beware! Thatch is one of only a few roofing materials that is combustible. Therefore, Thatchbatts® are the ideal product because they are non-combustible and will reduce the heat transfer around the roof timbers in the event of a fire!
Thatchbatts® are non-combustible, semi-rigid, high quality resin bonded mineral rock wool slabs. The Thatchbatts® have been manufactured to a width of 400mm, to allow them to be installed between the roof joists. They also have a high density for increased fire protection on the underside of thatched roofs.
Thatchbatts® can be also used to improve thermal and acoustic values. When Thatchbatts® are used in conjunction with other components in the roof system, they can help to achieve U-Values in the region of 0.16 to 0.14.
Thatchbatts® have been tested in conjunction with other products in our range as part of our systems.
Since the release of Thatchbatts®, we have seen most architects selecting a minimum of 100mm of Thatchbatts® to achieve increased fire protection and thermal values.
Thatchbatts® are designed to be friction fitted between rafters set at 400mm centres. Although the slabs, in most cases, are self supporting, we still recommend that consideration be given to following one of the wired fixing systems as detailed on the installation instruction document below.
When multiple layers of Thatchbatts® are being used, we recommend that the joints are staggered to give a more comprehensive solution.
Thatchbatts® - Installation Instructions
Although Thatchbatts® offer increased fire protection, where permitting they should be used in conjunction with either Thatch Firewall or Thatch Fireboard to create a comprehensive fire barrier system.
