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 compression fitted between the roof joists. They also have a high density for increased fire protection on the underside of thatched roofs.
Thatchbatts® are normally used in conjunction with either TAS100 Thatch Fireboards or Thatch Firewall Membrane to produce a comprehensive fire barrier in terms of both integrity and Insulation. 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 ranging from 0.12 to 0.18 depending on the thickness selected.

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.
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.
Thatchbatts® are designed to be friction fitted between rafters set at 400mm centres.
When multiple layers of Thatchbatts® are being used, we recommend that the joints are staggered to give a more comprehensive solution.
Although the slabs, in most cases, are self-supporting, we still recommend that consideration be given to also using one of our wired support systems. These are particularly relevant if the area below the Thatchbatts® is a traditional loft space.
- Please review Health & Safety practices regarding dust/fibre development or confined spaces – wear a suitable disposable face mask or other suitable approved respirator.
- All products will be supplied with Installation Instructions, which will need reviewing before completing any works.
