This is a new environmentally-friendly Heat Insulation material, which is soft, light and easy to install. Thermal Wrap Insulation during summer can block 97% of radiation heat coming from sun which can enter into building and balance heat will enter by conduction and convection (which is negligible). During winter Thermal Wrap keeps heat escaping from building by reflecting 97% of the heat back in the building. In turn requiring less work by your heating systems. Thus Thermal Wrap is the only solution for both summer and winter to save energy and money.Available : 2mm, 4mm, 6mm, 8mm, 10 mm, 12 mm, 20 mm.
