Now many people say that architectural glass film can be energy-saving, it is how to save energy in the end? Its energy-saving principles and energy-saving parameters how to quantify?
I say, mainly rely on reflection to heat, natural air conditioning will not open so much, this is not energy, as the coefficient, businesses have test equipment
Coated glass and hollow glass composite: including thermal reflective coating insulating glass and low-emissivity insulating glass. The former can also reduce the heat transfer coefficient and shading coefficient, which is better light transmission. The type and function of architectural glass foil
Insulating glass: insulating glass is made of two or more glass with aluminum hollow frame frame, sealed with cement or welding, the formation of free space in the middle, can be filled with dry air or inert gas, the heat transfer coefficient U than the single layer Glass is small, good insulation properties, but its shading coefficient SC reduced very little, the solar radiation heat reflex improved little.
Coated glass: coated glass is the surface of the glass coated with one or more layers of metal, alloy or metal compounds to change the performance of the glass. According to the different characteristics can be divided into heat reflective glass and low radiation glass.
Thermal reflection (sunlight control) glass, usually in the glass surface coated with one or more layers such as chromium, titanium or stainless steel and other metal or its composition of the film, the product was rich in color, visible light with the appropriate transmittance, Infrared has a high reflectivity, the UV has a very low transmittance, therefore, also known as sunlight control glass. Compared with ordinary glass, reducing the shading coefficient, that is, to improve the shading performance, but little change in the heat transfer coefficient.
Low-emission (LOW-E) glass, is the surface of the glass plating multi-layer silver, copper or tin and other metals or other compounds composed of thin film, the product has a higher transmittance of visible light, infrared has a high reflectivity, with Good thermal insulation properties, due to poor film strength, are generally made of hollow glass instead of using alone.
