When a thatched roof is stripped down to rafters, or on 'new build', the recommendation is the installation of PU28 Thatch Fire Barrier.
PU 28 is a medium weight fiber glass fabric with a specially
formulated aluminum pigmented and fire retardant polymer which provides
a heat reflecting surface as well as other properties for the
manufacturing of smoke and fire curtains, blinds, cavity wall fire
barriers and other types of smoke and fire control systems. As opposed
to a rigid fire-board, the material is flexible and will follow the
contours of an old roof structure. The material is halogen free, has an
improved resistance to hydrolysis (waterproof & breathable) and
offers a more rigid handle, it will not rip easily.
With a Class 0 fire resistance rating and satisfying BS 476 Part 6: 1989, Part 7 1997, it is acceptable, where required, for Building Regulations.
As an incentive to use this product, 'Thatch Fire Barrier' is, for a limited time,
offering to supply this to thatchers, builders, or individual home-owners, at
a very reduced rate.
1.3m x 50m - £500.00 per roll + haulage. There is no VAT to add on to this price, which makes it of great interest to non VAT registered thatchers, builders and home-owners.

The PU28 thatch fire barrier fabric is fixed on top of the rafters.
Strips can be laid vertically, to overlap & secure on a rafter,
to create a total fire seal, or can be laid horizontally. If the strips
are laid horizontally, it is essential to create a total fire seal and
have no sagging between the rafters.
Lay the fabric with a 100mm overlap, fold back to give a 50mm up stand -
Staple this together with 8mm staples at 500mm spacing. The join is then folded back on itself 25mm to give a continuous seal.
This fold then has a second run of staples at 100mm spacing to create the total fire seal.
As the thatching requires the ability to fix into the rafters, a counter batten is then fixed to the vertical line of each rafter. By then fixing horizontal battens, an air gap ,beneath the thatch, of about 50 mm is created.
