What is Low-e glass? what is the difference between Low-e glass and normal glass

Low-e glass

Nowadays,low-e glass is very popular in construction industry due to its high performance in preventing infrared ray, defending ultraviolet ray and harmful radiation in the sunshine,but low-e glass has two types according to production process--online and off-line.

Low-E glass(Low emissivity glass) is also called low radiation coated glass, it is one kind of special glass which coated with multilayer of very low surface radiation rate of metal or other compounds on the quality float glass by using magnetic sputtering method. 

It has low thermal conductivity and high light transmittance, ensuring visible light transmittance and reducing light pollution based on prevention of heat losses. 

According to glass coating technology , it has online Low-E coated glass and offline Low-E coated glass.

 Offline Low-E glass is one kind of soft coating low emissivity with a highly efficient energy saving products obtained through the use of the 

Magnetron Sputter Vacuum Deposition (MSVD) method where multiple layers of metal or nonmetal coats are applied on the surface of a

top quality float glass substrate. 

According to the structure of Low-E coating, Low-E glass can be classified as single silver Low-E glass, double silver Low-E glass and

triple silver Low-E glass,

The differences among various types of glass is reflected in their spectral data as  shown in the following figure


1.High efficiency in energy saving and environment production

2.High performance in visible light transmittance

3.Stable chemical performance

4.Stable performance in thermal processing.

It is easy for hot bending, tempering or semi-tempering and laminating, easy to process like common glass, and durable.

5.Stable mechanical performance for solid coat, high abrasion and scratches resistance Performance


See the attached parameter data.



Specification:

Thickness: 3mm,4mm,5mm,6mm,8mm,10mm,12mm,15mm,19mm

Size: 1830x2440mm, 2134mmx3300, 2134x3660mm ,2440x3300mm,2440x3660mm

Colors: clear, grey, green, blue and bronze.

Application:

The application is wherever there is a need for enhanced thermal insulation and it achieves 

optimum performance from double glazing and laminating. It’s widely in façade glazing, 

window double glazing,commercial buildings, gymnasium and schools etc. 

Principle of LOW-E Glass:

Because the heat always flows from the end with high temperature to the end with 

low temperature, it is easy to flow to outside from inside in winter, but from 

inside to outside in summer. The coating of offline LOW-E coated glass can effectively inhibit the

heat loss, make the sunshine reach the inside and indoor heat obtained from the sunshine and central 

heating stay without flowing outdoors, therefore, the interior is warmer and more comfortable in winter. 

However, in summer, it can prevent the exterior heat from entering the room to ensure higher refrigeration

performance of indoor air-conditioner and reduce the living cost.
