Thatchsayf Fire Retardant Coatings
Protect your thatch from any and all damage that mother nature can throw at it. We offer both fire retardant coatings and steel tile option; Harvey Thatch Tiles
We are a licensed “Micon Thatchsayf” applicator.
Thatchsayf, which took years to develop, provides protection of thatched roofed structures against the ravages of fire, whether initiated by electrical short circuit, lightning or any other source of fire.
The mechanism of the protection is two-fold, on exposure to heat, the fire retardant chemicals react with the cellulose to form esters, giving a more stable base for the intumescent layer on the surface and the intumescent layer foams to form a protective char that restricts oxygen flow to the surface and also reduces the surface temperature of the thatch.
Environmentally Friendly
This invention differs from many conventional fire retardants, which rely on dehydration of the cellulose to form a carbon backbone when the volatiles are paralysed off.
Thatchsayf is environmentally friendly as it is biologically acceptable and no flammable or harmful solvents are used during the application.
The coating is clear and does not alter the natural aesthetics of thatch, in fact, it prevents discoloration for a longer period of time. In addition, the coating improves compaction of thatch without hindering its ability to breathe, thus preventing bacterial and fungal growth. It is the only product applied to both interior and exterior thatching for maximum protection.
Certified & Guaranteed.
On completion of a contract, Micon Coatings will issue a certificate to confirm the correct amount of product has been applied in accordance with the CSIR specification. On the same certificate, the expiry date, which for outer application is 7 years, is also recorded, the interior of the structure should not have to be retreated.
As of today, Micon Thatchsayf is the only product to have been tested and passed the stringent ASTM E108 test method, a requirement of the new South African National Standard Thatched Roof Construction Specification (SANS10407).
Most of the the major insurance companies in South Africa allow premium savings when Thatchsayf is applied.
