Energy-efficient Soft Coat Low-E Glass

Single Silver Double Silver Triple Silver Low E Glass

Low-emissivity or low-e glass is a type of energy-efficient glass that is designed to prevent heat from escaping to the cold outside environment through your windows. Low-e glass has a thin, transparent coating of tiny metal oxide layers that drastically reduces heat transfer and reflects the internal heat back into your room.

The coating is not visible to the naked eye, allowing as much natural light as possible to enter the house. However, even if it is transparent, this coating protects your home from unwanted UV rays (UV rays) that can harm your skin, fade your carpets and wall coverings and damage your furniture. In addition, it helps control the radiant heat (infrared light) that enters and exits a room. In other words, it keeps your home warmer in the winter and cooler in the summer. This saves money by reducing heating and cooling bills, while creating a comfortable living environment.

Low-e glass is essential for rooms or buildings with a high proportion of windows or glass doors, such as conservatory, living rooms, offices. The use of low-e glazing helps to retain heat even in winter, allowing you to comfortably use these rooms for more months of the year. Low-e glass is also recommended for north or east facing windows, where a larger proportion of heat loss is expected. For south and west facing glazing where overheating can become a problem in the summer months, it is recommended to use solar control low-e glass.

Low-e glass windows not only keep the heat in during winter, they can also reflect it back out during summer. They literally pick out and refuse entry to certain portions of the light spectrum. Therefore, they allow less infrared light (radiant heat) to enter the house, keeping it cooler during the summer months thus reducing operating costs related to air conditioning.

The difference between single silver low-E ,double silver low-E and triple silver low-E

1.  Light to Solar Gain (LSG): Measures the ratio of visible light to solar heat gain (LSG = VLT ÷ SHGC).

     The LSG of single silver low e is around 1.4,while double silver one can be over 1.6-2,triple silver low e LSG can reach 2.2 or even more, which means that under the same light transmittance,the double silver low e and triple one can reach lower SC value and transfer the lighting to cold light.

2.U value.
Single silver low e U value is about 1.7-1.85.
Double and triple silver low e U value is around 1.5-1.65 with better thermal insulation performance.

3. Costs.
Triple silver low e costs about USD10/sqm higher than the double. Double silver low e glass costs about USD3-4/SQM higher than the single .

In terms of cost-effectiveness, we recommend double silver low e.

We are one of the leading suppliers of glass products in China. Our neutral-coloured, triple-silver low-emissivity glazing product offers a balance of year-round thermal comfort and visibility. It is mostly double glazed in an Insulating Glass Unit (IGU) in a variety of make-ups depending on the aesthetic and performance requirements.
