Features of low e insulated glass and thermal insulating glass
High-performance low e insulated glassand thermal insulating glass, due to a special metal film, can achieve a shielding factor of 0.22-0.49, which reduces the load of indoor air conditioning (air-conditioning). The heat transfer coefficient is 1.4-2.8W (m2.K), which is better than ordinary insulating glass. It also exerts great efficiency in reducing indoor heating load. Therefore, the larger the window is opened, the more obvious the energy saving effect.
②Improve the indoor environment
High-performance low e low e insulated glass and thermal insulating glass and thermal insulating glass can intercept considerable energy from the sun into the room, thus preventing discomfort caused by radiant heat and reducing dazzling caused by sunset sunlight.
③Rich tones and artistry
High-performance low e insulated glass and thermal insulating glass has a variety of colors, which can be selected according to needs to achieve a more ideal artistic effect.
④Use of high-performance low e insulated glass and thermal insulating glass
It is suitable for office buildings, exhibition rooms, libraries and other public facilities and special buildings such as computer rooms, precision instrument workshops, and chemical factories that require constant temperature and humidity. In addition, it can also be used for sun protection and anti-dazzling places.
Note: Dry air is enclosed in the hollow glass, so according to the temperature and air pressure changes, the internal air pressure also changes, but only a small deformation occurs on the glass surface. In addition, slight warpage may occur during manufacturing, and distortion may also be formed during construction. Therefore, including such factors, sometimes there are corresponding changes in reflection, which should be paid attention to. Different colors have different reflections.
Gold, copper and silver metal coatings have high reflectivity in the mid-to-far infrared region, that is, when the wavelength range is greater than 4μm. If the metal coating has a typical thickness, the total reflectivity can reach 90%-95%, and the high infrared reflectivity is equivalent to the low emissivity (Low-e), which will reduce the radiation conversion between the inner and outer glass plates of the insulating glass module. Correspondingly, compared with the standard hollow glass member with an air layer of 12mm, the thermal 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). By reducing the thickness of the metal layer, the light transmittance can be increased to about 60%-60%. This kind of extremely thin coating has a very good protective effect, while still having a high infrared reflectance value, in the range of 85% or 75%. The air layer is 12mm filled with heavy gas in the middle, and the insulation value of the coating can reach 1.6-1.9W/(m2.K).
low e insulated glass and thermal insulating glass is mainly used in buildings that require heating, air conditioning, noise prevention or condensation, and no direct sunlight and special light. It is widely used in residences, restaurants, hotels, office buildings, schools, hospitals, shops and other occasions that require indoor air conditioning. It can also be used for doors and windows of trains, automobiles, ships, and freezers. [2]
Hollow glass is mainly used for outer glass decoration. Its optical performance, thermal conductivity, and sound insulation coefficient should meet national standards. Only when the structure is reasonable and the design meets the standard can the insulating glass exert its heat insulation, sound insulation, anti-theft, and fire prevention effects. Using vacuum double-layer tempered glass can reach laboratory standards! There are also hollow glass with inert gas and color pigment gas added on the market, as well as the addition of beautiful scenery strips for reinforcement and decoration.
The role of hollow glass aluminum spacers: Aluminum is called an active metal element, but a dense oxide film will form on its surface in the air, preventing it from continuing to interact with oxygen and water. It can react with oxygen at high temperatures and release a lot of heat. With this high reaction heat, aluminum can replace metal from other oxides (thermite method).
