Fire Retardants

Virtually all thatch fires occur in traditional English thatched houses. Research has shown that the vast majority of thatch fires are chimney related, as many as 90%. The majority of thatched properties have chimneys built prior to the 1960`s when chimney construction was only a single brick thickness. Old English thatched buildings often have poor quality chimneys, and most fires occur in the winter when hot gases break through a poor quality chimney and ignite the thatch surrounding the chimney.

Naturally untreated African cape thatching reed offers far greater fire resistance than alternative traditional English thatching materials. For those customers who may have concerns about possible fire risks, we can supply all our thatch tiles and thatched structures pre treated with a specialist fire retardant chemical.

Please Note: Fire retardant treatment is currently NOT a legal requirement for outdoor garden buildings.

Fire retardants reduce the flammability of materials by either blocking the fire physically or by initiating a chemical reaction that stops the fire. The particular fire retardant chemical used by thr African Thatch Company is called Flame Stop I-DST.

Flame Stop I-DST Thatching Chemical Fire Retardant:

Flame Stop I-DST is a highly concentrated fire retardant used for `hard to penetrate` materials such as thatching, bamboo, closed cell foam and other non-porous materials. This product prevents the spread of flame by developing a self-extinguishing chemical reaction. Flame Stop I-DST was found to be highly effective on thatching due to the flame spread rating of "10" obtained by testing using the ASTM E-84 Standard at Omega Point Laboratories. Flame Stop I-DST is a clear, odourless, non-toxic and non-corrosive fire retardant chemical.

Flame Stop I-DST chemical fire retardant is also available to purchase in liquid format in 5L, 25L and 208L (55US Gallon) containers.

Flame Stop I-DST Application For Thatch:

Dipping Method:
When dipping, please ensure that all thatch is completely submerged in Flame Stop I-DST. Keep the thatch submerged for a minimum of 15 minutes. Let it air dry for a minimum of 36 hours. Before testing thatch make certain the Flame Stop I-DST has had time to cure for 48 hours. When batch testing, hold the thatch at a 45 degree angle and try to light with a lighter, if the thatch flames for more than 5 seconds after the flame is taken away, retreat the thatch.

Spraying Method:
Spraying should be performed utilising an air less sprayer. Spray from the top down to all sides and underneath with a heavy coat. All thatch must be completely saturated with Flame Stop I-DST.

Flame Stop I-DS has been tested to the following standards;
