Comparison Between LOW-E Glass and Ordinary Insulating Glass

Click: -Time:2022-11-11 17:02
1. High permeability LOW-E glass
Product characteristics:
a) High visible light transmittance: natural lighting, transparent effect:
b) High solar energy transmittance, more solar heat radiation through glass;
c) Extremely high reflectivity of medium and far infrared rays: excellent thermal insulation performance, low U value (heat transfer coefficient). Applicable scope: cold northern region. In winter, the solar heat radiation enters the room through the glass to increase the indoor heat energy, while the far-infrared emitted by the indoor heating, household appliances, human body, etc. is separated and reflected back to the room, effectively reducing the heating energy consumption:

2. Sunshade LOW-E glass
Product characteristics:
a) Suitable visible light transmittance, with certain coverage for outdoor strong light;
b) Low solar transmittance, effectively prevent solar heat radiation from entering the room;
c) The extremely high reflectivity of medium and far infrared rays restricts the entry of outdoor secondary thermal radiation into the room.
Shared scope: shared in the southern and northern regions. This product not only restricts some solar heat to enter the room in winter, but also restricts more solar energy to enter the room in summer, because the intensity of solar energy in winter is only about 1/3 of that in summer, so the thermal insulation performance is not affected. From the perspective of energy-saving effect, the sunshade type is not lower than the high permeability type:
3. Double silver LOW-E glass
Product characteristics: Double silver LOW-E glass, named after the double silver layer in its film, belongs to a more complex type of LOW-E glass film system structure and is a high-grade LOW-E glass. It highlights the covering effect of glass on solar thermal radiation, and ingeniously combines the high transmittance of glass with the low transmittance of solar thermal radiation. Therefore, compared with ordinary LOW-E glass, it has a lower solar transmittance with the same visible light transmittance.
Shared scope: It is not limited by region, and is suitable for vast regions with different climate characteristics.
