Systems

We recommend that TAS100 Thatch Fireboards be used in conjunction with Thatchbatts® to create a comprehensive fire barrier, meet the criteria of the Dorset Model and increase thermal insulation values. Not installing correct levels of insulation can increase the risk of condensation, whilst consideration should also be given to the installation of a suitable vapour control layer (VCL).

Application

TAS100 Thatch Fireboard is a very easy product to handle despite the apparent rigidity. It must be installed in a professional ‘tradesman – like’ manner to get the desired durability and perfect finish.

Installing

TAS100 Thatch Fireboards are positioned on top of the roof rafters with the smooth side facing upwards and fixed down with either nails or screws. When fixing the boards, the first row is normally laid out horizontally along the eaves and then working towards the ridge, each subsequent row of fireboard is laid in a way so the joints are staggered. All joints need to be sealed with a bead of intumescent joint sealant. Battens are then fitted horizontally over the top at 300mm centres, with the first batten 125mm from the arris rail. All the framing and substances used must comply with relevant building regulations and standards.

Cutting

TAS100 Thatch Fireboard sheets are cut very easily using a carbide tip knife. For rough cuts, place the TAS100 Thatch Fireboard sheet rough side up, scour along the straight line with a knife, then snap the other side to separate the two sheets to get a clean cut. Finer cuts are achieved by using a saw. Please review Health & Safety practices regarding dust/fibre development or confined spaces – wear a suitable disposable face mask or other suitable approved respirator.

Fixing

TAS100 Thatch Fireboard FixingTAS100 Thatch Fireboard may be screwed or nailed on to the frame as appropriate. Use fasteners suitable for the roof rafters in place, ensuring that the screws have enough length to provide a good grip to the roof rafters, with centres being between 150 and 200mm. When using self-embedding screws ensure that they do not go more than 0.5mm below the surface of the board, and kept no more than 12mm away from the edges, and 50mm away from the corner of the board. Furthermore, ensure that screws do not over-spin, thus losing grip of the frame.

General Notes

Please consult your architect or building control officer with regard to the required insulation values and the need for a vapour control layer (VCL).

  • All the framing and substances must comply with relevant Building Regulations and Standards.
  • All components of this system should be installed in a professional like manner and in strict accordance with our instructions.
