Both products have been well received internationally, and pre-treated thatch material and timber are exported around the world.
Thatchbor, for the treatment of grass and reeds for thatching, and Flambor for timber are “one-step”, “once-off” products which can significantly reduce the risks of fire hazards while minimising natural decay and decomposition. At the same time an innovative treatment process with Thatchbor ensures that grass and reeds are treated right to the core, according to the joint developers of the patented products, South African companies TimberLife and Micon Coatings.
Normally the waxy layer on the surface of grass and reed prevents the absorption of treatment products into the stem. Thatchbor has been specifically developed for impregnation, which allows penetration right into the core of the grass. “For the first time, the full depth of a thatch roof is treated, eliminating the risk of an untreated core,” says TimberLife director Willie Conradie.
Once the stem has been impregnated, the effects of leaching are minimal and the protection is permanent. Unlike conventional spray-on applications, no further treatment is required.
An added benefit is that the action of the biological preservative in Thatchbor reduces allergens in thatch which often cause allergies in children.
Both products have been extensively tested and approved by the South African Bureau of Standards (SABS) and the (CSIR) in accordance with German, British and American test procedures. Quality assurance is strictly monitored by these institutions.
A number of companies are exporting timber and thatch treated with the products. Demand is from all over the world, and especially so from America. “Its popularity is mainly due to the combination of preservative and fire-retardancy in one product, at a lower price than using two separate treatments,” says Johannesburg exporter Roy Smith, MD of Mintroad Sawmills.
