Thatchbatts

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.

Testing

Thatchbatts have been tested by The Loss Prevention Council in conjunction with other products in our range as part of a system. Please contact us for further information.

Application

Six top hat brackets are required for each slab and these are nailed to the top of the rafters using galvanized nails. 50mm or 100mm brackets are available subject to the thickness of Thatchbatt required.

Thatchbatts are then positioned between the rafters on top of the top hat brackets.

If 100mm is required then 2 x 50mm slabs are laid ensuring that all horizontal joints are staggered

Systems

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.
