Custom Grass Thatch – Tests


Africa Roofing Inc. has done substantial tests in establishing grass and reed roofing as an accepted roofing design. Test done on Thatchbor grass with a reed “spreilaag”. Exposed surface have an application of Fire retardant (Firex238).

 
Results achieved in 2001

    1. Wind driven Rain Test, to the International Conference of Building Officials (ICBO) Acceptance criteria for special roofing systems (AC07). ICBO has been the preeminent source of building and construction codes for more than 75 year. The result passed with no water penetration.
       

    2. Burning Brand fire test, to American Society for Testing and Materials (ASTM) Test Method E108 Standard Test Methods for Fire Tests of Roof Coverings. We archived a class A rating. Class A rating are applicable to roof coverings that are effective against severe test exposure, and afford a high degree of fire protection, and do not present a flying brand hazard.
       

    3. Spread of Flame, fire test, to American Society for Testing and Materials (ASTM) Test Method E108 Standard Test Methods for Fire Tests of Roof Coverings. We archived a class A rating. Class A rating are applicable to roof coverings that are effective against severe test exposure, and afford a high degree of fire protection.
       

    4. Intermittent Flame, fire test to American Society for Testing and Materials (ASTM) Test Method E108 Standard Test Methods for Fire Tests of Roof Coverings. We archived a Class B rating. A Class B Tests are applicable to roof coverings that are effective against moderate test exposure, and afford a moderate degree of fire protection.
       

    5. Wind Load, ASTM E330 Standard Test Method for Structural performance of exterior components to a static air pressure. Our test panel withstood wind pressure equivalent to 200 Mile Per Hour winds without failure.
       

    6. Accelerated Weathering of Fire-Retardant Treated wood products for fire testing, ASTM D2898-94. Our test panels were subjected to over 2000hrs of rain and heat, and then a Intermittent flame test and Burning brand fire test done on panels. The results archived were better then thatch panels that had not been subjected to the 2000 Hrs Weather tests, showing that the Pressure Treated Thatchbor does not leach out with extensive rain and heat.

In November 2002 Africa Roofing did a series of Fire Test on Thatchbor Pressure Treated grass with a reed “spreilaag” but with exposed surface having an application of sprayed on Thatchsaf. The reason for applying the Thatchsaf as opposed to the Firex238, was because the Firex238 was gluing the top surface of the thatch together making it impossible to maintain and also not allowing the thatch to breath causing the thatch to deteriorate.

 

The results of the tests was that (1) Burning Brand fire test (ASTM) E108, we archived a class A rating. (2) Spread of Flame, (ASTM) E108, we archived a class A rating. (3) Intermittent Flame, (ASTM) E108, we archived a Class B rating. The results were much the same as when using Firex238 except now the thatch could be maintained and could “breath” under the Intumescent coating of Thatchsaf.
