Heat Flows from a hot or warm medium to a cold medium in 3 ways:Radiation Conduction Convection,and radiation occupies an important position.Enviro-tuff is specially designed for roofing installation especially in tropical condition.The key function is to reduce the heat transfer and maintain a comfortable temperature in a building.With the installation of Enviro-tuff, 96% of radiant heat is reflected and prevent from transferring to the building

1.High Reflectivity

Thermal insulation: According to the test of ASTM, the heat transformed by Radiation usually takes up to 90%;

2.High Strength

Enviro-tuff Radiant Barrier Significantly in Tensile Strength, Tear Resistance and Longer lasting Performance;

3. Waterpfoofing

Hydrostatic Pressure Test >2m H2O

4.WVTR(water Vapour Transmission Rate)>300m²/d

5.R Value

R=1.27(m2K) / W (3CM Air Ventilation )

6.Fire performance

Calss-A2 (GB8624)
