Characteristics Of Insulating Glass

① Significant energy-saving effect
High performance insulating glass, with a special metal film, can achieve a shielding coefficient of 0.22-0.49, reducing indoor air conditioning (cooling) load. The heat transfer coefficient is 1.4-2.8W (m2. K), which is better than ordinary insulating glass. It also plays a significant role in reducing indoor heating load. Therefore, the larger the window, the more significant the energy-saving effect.
② Improving indoor environment
High performance insulating glass can intercept a considerable amount of energy emitted from the sun into the interior, thereby preventing discomfort caused by radiant heat and reducing glare caused by sunset sunlight.
③ Rich color tones and artistry
High performance insulating glass has multiple colors, which can be selected according to needs to achieve more ideal artistic effects.
④ Application of high-performance insulating glass
Suitable for public facilities such as office buildings, exhibition rooms, libraries, and special buildings such as computer rooms, precision instrument workshops, chemical factories that require constant temperature and humidity. In addition, it can also be used for sun protection and protection against glare from sunset light.
Attention: Dry air is sealed in the middle of the insulating glass, so the internal air pressure changes according to the temperature and pressure, but only a small deformation occurs on the glass surface. In addition, slight warping may occur during manufacturing and distortion may also occur during construction. So, including such factors, sometimes there are corresponding changes in reflection, which should be taken seriously. The reflections vary depending on the color chosen.
Gold, copper, and silver metal coatings in the mid to far infrared region, i.e. wavelength range greater than 4 μ At m, the reflectivity is very high. If the metal coating is of typical thickness, the total reflectance can reach 90% -95%, and the high infrared reflectance is equivalent to low emissivity (Low-e), which will reduce the radiation conversion of the inner and outer glass panels of the insulating glass component. Correspondingly, compared with the standard insulating glass component with an air layer of 12mm, its insulation value can range from 0.3W/(m2. K). In addition, if the air in the component is replaced by heavy gas, its insulation value is 1.4W/(m2. K). By reducing the thickness of the metal layer, the transmittance can be increased to around 60% -60%. This 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 and filled with heavy gas in the middle. The insulation value of the coating can reach 1.6-1.9W/(m2. K).
