Sunscreen film using PET (polyethylene) substrate, a leading multi-layer metal sputtering and vacuum technology and thin film physics and plasma technology, chemical technology, it has a very high thermal efficiency, high tension, high elongation, strong anti-acid properties. And rich natural color, test results showed that: 81% of the solar energy barrier; when the outdoor temperature is 38-39, compared with ordinary glass temperature 3-5 degrees lower, saving more than 30% of the air-conditioning power consumption, high-tech and energy security materials. (1) at the UV: Paste Weibang insulation film can cut off 99% of UV rays, greatly reducing indoor furniture fading due to UV-induced prolong the life of furniture. (2) safety and explosion: a proof function to prevent ordinary glass and broken glass caused by natural bodily injury, personal protection. (3) heat rate as high as 79%, a film = 24 cm brick, can effectively cut off from the solar heat radiation and heat conduction, saving air conditioning costs. Improve HVAC efficiency, cooling capacity without increasing expensive. (4) to reduce glare, indoor outdoor look more comfortable, keep an eye on comfort. (5) retain privacy - after the film, see outside the house, and this film has high light transmittance, unlike curtains, do not have to sacrifice your beautiful vision is also to preserve privacy, but also your living space free
