Anti-ultraviolet coating and heat insulation coating can suppress the energy of ultraviolet ray and infrared ray. Also stop the heat transfer. These coatings will reflect the energy to the air in order not to collect the energy on the surface. Meanwhile, the low heat conductivity will be added into the coating in order to prevent the heat transfer. No matter how high the temperature it is, Nano-Tech Metal Roof can block the heat transfer in order to keep the temperature steady indoor.
