Envirotuff 202FR

Envirotuff 202 is Fire Retardant as required by the new SANS and TIASA national building regulation. It is a light super strong underlay specially formulated for roof, waterproof and dust proofing of buildings. It is a double-sided reflection foil with super strong woven Polyethylene reinforcing. 202 can withstand temperatures between -30°C and 100°C and will not shrink, crack or delaminate. Envirotuff has superior emissivity and reflects at least 95% of radiant heat. Envirotuff 202 has a 1.89 R-Value.

  • Finished mass: +- 7,35kg
  • Roll dimension: 1250mm x 40m
  • R-Value: 1.89


Envirotuff products should not come into contact with wet concrete or other lime based products and must be stored in a dry place out of direct sunlight.


Envirotuff should be layed across the rafter or purlins with a 150mm overlap and fixed down with the battens. Under no circumstances should the roof cladding be fixed in direct contact with Envirotuff. To ensure optimum performance, Envirotuff should be installed with a minimum adjacent airspace of 25mm. For best results, it is recommended that Envirotuff is pulled hand-taut across rafters but not overly so. In high wind areas, the use of wind flap panels is recommended.

NB: Due to its pliable nature, some stretching of Envirotuff may occur during installation. This may cause micro-cracking of foil surface allowing light through the product. This will not affect the serviceability or durability of the product. Envirotuff is not designed to withstand prolonged direct exposure to the elements. Upon application of this product, the outer roof or wall should be installed without delay

Due to its high reflectivity (0.96 - 0.97) and low emissivity (0.04 - 0.031), it is an ideal insulation membrane when used in conjunction with an air space.
