High-performance insulating glass, due to a special layer of metal film, can reach 0.22-0.49 shielding coefficient, so that indoor air conditioning (cooling) load reduction. Heat transfer coefficient 1.4-2.8w (M2.K) is better than ordinary insulating glass. To reduce the indoor heating load, also play a great efficiency.
　　Therefore, the larger the window opens, the more energy-saving effect is more obvious.
　　② Improving the indoor environment
　　High-performance insulating glass blocks the amount of energy emitted by the sun into the room, thus preventing the discomfort caused by radiant heat and lightening the glare of the sun's glow.
　　③ rich in colour and artistry
　　High-performance insulating glass has a variety of colors, can be selected according to the needs of color, in order to achieve a more ideal artistic effect.
　　④ High performance insulating glass applications Applicable to office buildings, exhibition rooms, libraries and other public facilities and such as computer room, precision Instrument workshop, chemical plant and other special buildings requiring constant temperature and humidity.
　　It can also be used for sunscreen and anti-glare spots. Note: Insulating glass in the middle of the dry air, so according to the temperature, pressure changes, the internal air pressure changes, but the glass surface only a small deformation. In addition, the manufacturing may produce a small warpage, the construction process may also form a distortion. Therefore, including some of these factors, sometimes reflect the corresponding changes, should be paid attention to.
　　The colors are different and the reflections vary. Gold, copper and silver metal coating in the Cosco infrared region, that is, the wavelength range is greater than 4μm, the reflectivity is very high. If the metal coating is a typical thickness, the total reflectivity can reach 90%-95%, the redshift external reflectance is equivalent to low emissivity (e), which will reduce the insulating glass components inside and outside glass plate radiation conversion, and accordingly, with the air layer is 12mm standard insulating glass members, the insulation value can be from 0.3w/( M2. K). In addition, if the air in the component is replaced by heavy gas, the insulation value is 1.4w/(M2. K). Reduce the thickness of the metal layer, the transmittance can be increased to 60%-60% or so. This extremely thin coating has a very good protective effect and still has a high IR reflectance value in the range of 85% or 75%. The air layer is filled with heavy gases in the middle of 12mm, and the insulating value of the coating can reach 1.6-1.9w/(m2). K).
