Low Emissivity Glass
Low emissivity glass (also called as Low-E glass) is coated with a film system composed of multiple layers of silver, copper,tin and other metals or their compounds on the surface of the glass. The product has high transmittance to visible light, high reflectivity to infrared, and good heat Insulation performance, mainly used in construction and vehicles, ships and other vehicles.
Features:
Excellent thermal performance
1.Low-E glass manufacturing doors and Windows of buildings, can greatly reduce the radiation caused by the transfer of indoor heat to the outdoor, to achieve the ideal effect of energy saving.
2 .If low-E glass is used, the amount of fuel consumed for heating can be significantly reduced due to the reduction in heat loss, thus reducing the emission of harmful gases.
3. Low-e glass can meet the requirements of winter and summer. It can not only heat preservation and heat insulation, play the effect of environmental protection and Low carbon.
Good optical properties
The visible light transmittance of low-e glass varies theoretically from 0% to 95% (6mm white glass is difficult to achieve), and the visible light transmittance brepresents the indoor daylighting.
Technical Parameters
Data are calculated by WINDOW6.3 developed at Lawrence Berkeley National Laboratory,except for having been given clear indication of standards. The glass performance data will be finalized by the performance data sheet which submitted by LONGLASS . Attached performance is just for design reference.
