Low-Emissivity glass (Low-E glass) is a kind of specialty glass with excellent functional performance characteristics of solar control. Such glass is generally coated with multi-layers of metal oxides and some other materials, designed to allow transmission of high level of visible light, and reflect UV and infrared radiations. In order to satisfy customers' diverging demands for Low-E glass installation under different climatic conditions, a full range of Low-E glass products are produced, covering High Transmittance Low-E glass; High Shading Low-E Glass; Double Silver Low-E glass; Temperable Low-E glass.
High Transparence Low-E Glass
Functional Performance Characteristics:
1. High level of visible light transmission: excellent natural lighting with neutral color effect.
2. High level of solar energy transmission: good solar energy transmission, with shading coefficient (SC) greater than 0.5.
3. High reflectance of infrared radiation: effective control of heat loss from building, with a thermal conductivity value (U Value).
Product Applications:
1. Most suitable for the installations in the regions with cold weather. Such installation can allow most of solar energy transmitting in while reflecting the infrared radiation back to indoors from domestic appliances and human bodies, thereby reducing its indoor energy consuming effectively.
2. The glazing installations requiring a high level of sunlight, with neutral aesthetic appearance.
High Shading Low-E Glass
Functional Performance Characteristics:
1. Desirable level of visible light transmission: reduce solar heat gain through higher reflection.
2. Lower solar energy transmission: effectively reduce solar heat radiation into interior of building, providing good solar heat insulation with a Shading Coefficient (SC) less than 0.5,
3. High reflection of infrared: with a relatively low heat gain or heat loss value (U Value); effectively reduce secondary infrared radiation from passing through glass into interior of building.
Product Applications:
1. Suitable for the installations in southern region as well as in northern region. It can effectively reduce much more solar heat transmission through glass into interior in summer than that in winter. On balance, it can provide an effective overall solar heat control function since the solar energy intensity in winter is only 1/3 of that in summer.
2. With reduced light transmission through the glass, it also provides good reflective and decorative effect.
Double Silver Low-E Glass
Functional Performance Characteristics:
Double silver Low-E coated glass is a more complex high performance specialty coated glass, incorporated two layers of silver oxide coatings. The double silver coated glass has the following functional performance characteristics:
1. High level of visible light transmission: provide a natural lighting, with a neutral exterior appearance.
2. Very low shading coefficient: effective in reducing solar heat radiation from reaching the building interior, especially for infrared heat radiation.
3. Very low heat gain or heat loss value (U Value): good heat Insulated, effectively reduce heat gain in summer and heat loss in winter.
Production Application:
Suitable for general application under various geographical locations and climatic conditions.
Temperable Low-E Glass
The soft-coated metallic layers are relatively unstable; hence it usually needs to be used in the insulated Glass unit within a short period. We have been able to improve the adhesions between different coated layers and the stability of the layer structure so that the soft-coated Low-E glass can be subjected to tempering or further processing.
Production Capability:
Standard Size: 2440mm x 3660mm
Maximum size: 2540mm x 4500mm
Glass Thickness: 3mm to 19mm
Quality Standard: GB/T18915.2-2002
Low E Glass
Low Emissivity Coated Glass (Also Called Low-E Glass) Is Made By Vacuum Magnetron Sputtering Coating Device To Form Metal Or Compound Films On The Glass Surface. The Coatings Have Complex Structure, So The Coating Machine Should Have Very Strong Production Capacity And High Technical Control Precision.
Our Low-E Glass Products Include High Transmittance Low-E, Solar Control Low E And Double Silver Low E. Our Temperable Low E Glass, Introduced Specific Materials And Structures, Is Allowed To Heat Treat/Temperable.
Another Feature Of Our Temperable Offline Low E Glass Is That It Can Be Processed At Another Place. With The Vacuum Aluminum Film Package, The Glass Is In Good Quality In 9 Months, Suitable For Long Way Transportation. The Coating Is Protected By Film, Massively Enable Easy Process Far Away.
The Features Of Low-E Glass Are Attributed To Silver Coating. The Oxidization Of Silver Means Low-E Glass Loses Its Low-Emissivity Function. Therefore, Low-E Glass Cannot Be Directly Exposed To The Air, And It Should Be Made Into Insulating Glass Unit For Use.
We Also Have Online Low E glass, With Netural Color(Colorless) Or Blue Grey Color. It Is Tempereable And Can Be Used Monolic.
Color of low E glass:
Neutral, Light Grey, Silver Grey, Light Blue, Blue Green And Other Colors In Different Shades
