Low Emissivity Glass

Low-emissivity glass normally refers to low-e glass, is one type of coated glass which is designed for energy controlling. Its coating layer has the characteristics of high transmission of visible light and high reflection of infrared rays. Therefore, it is widely used as an energy-efficient glass in doors and windows of buildings. There are currently two main production methods, online high-temperature pyrolytic deposition (online production) and offline vacuum magnetron sputtering (offline production).

The difference between low-E glass produced by these two methods

 

Low-e glass produced through online production methods has a durable coating layer, which can be used as a single piece and can be stored for a long time. But its thermal properties are not very well and its product categories are relatively simple.


Low-e glass produced by offline methods has better thermal insulation performance and comes in various colors, but its film layer has poor firmness and will be corroded by moisture and oxides when exposed to the air for a long time. Therefore, we'd better make it into insulating glass and use it within a few months.

 

Energy efficient

 

Low-E glass is an ideal material for insulated glass, which can offer excellent thermal insulation properties. In summer, it can prevent excessive external heat from entering the room. In winter, it stops heat loss from the house. This significantly reduces the energy consumption of the heating or air-conditioning system.

 

High transmittance of visible light

 

Highly transparent low-e glass has good visible light transmittance, which can provide building occupants with more comfortable natural light while reducing heat radiation.

 

Applications of Low-E Glass
Curtain wall glass
Windows and doors glass
Other architecture glass

Specifications And Processing

The size and thickness refer to the specification of float glass sheet.
When used as insulating glass unit, it can be made into double or triple glazing. Cutting to size, lamination and glass tempering are available.
