Experts : 90% of The Buildings in China Need to Be Coated

(China Glass Network) As the same function of auto glass film, film for architectural glass also owns effect of heat insulation and heat preservation. Experts say that 90% of the buildings in China need to be coated, only 10%~15% of the new buildings of our country can meet mandatory energy saving standard set by the government per year. Lacking of professional knowledge, common consumers should pay attention to parameter of the film and avoid choosing product of inferior quality. Visible Light Transmission The premier function of doors and windows is daylighting and ventilation, glass film with high visible light transmission can help reduce indoor daylighting consumption. Visible light transmission of the film should be no less than 60%. Infrared Blocking Rate Infrared ray occupies 54% of the total heat, higher blocking rate is better for energy saving. Infrared blocking rate of common film is more than 70%. UV Blocking Rate UV blocking rate is the index to measure indoor ultraviolet, the rate can be adjusted by requirement and common index is over 95%. There are about 50 billion square meters of high energy consumption buildings need to be transformed and glass account for 15 billion square meters. Consumption of architectural glass is about 12 million square meters each year. Building heating energy consumption of our country is three times than that of developed countries. With film coating on the surface of glass, temperature range of indoor and outdoor can be 5~8℃, saving 30% energy consumption of the air conditioning. Governmental guiding opinion for development of glass film and subsidy policies for energy saving reconstruction work of doors and windows have been issued early this year. Glass film with high light transmission and excellent heat insulation performance will be the mainstream development trend and direction. Source: GlassInChina
