Description

Low emissivity glass (Low e glass) is a kind of specialty glass with excellent functional performance characteristics of solar control. Low e glass is generally coated with multi-layers of metal oxides and some other materials, designed to allow transmission of high level of visible light, 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).

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.

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.

Temperable offline 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/off line low e glass can be subjected to tempering or further processing.

Applications:

High Transparence Low e Glass Applications:

1. High Transparence Low e Glass is 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 high transparence low e glazing of installations requires a high level of sunlight, with neutral aesthetic appearance.

High Shading Low e Glass Applications:

1. High shading low e glass is suitable for the installations in southern region as well as in northern region. High shading low e glass can effectively reduce much more solar heat transmission through glass into interior in summer than that in winter. On balance,  high shading low e glass 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, high shading low e glass also provides good reflective and decorative effect.

Double Silver Low e Glass Application:

Double Silver Low e Glass is suitable for general application under various geographical locations and climatic conditions.

High transparent Low e glass provides high visible light transmittance, high solar power transmittance and extremely high XIR reflectance. Its light exterior colors are applied to buildings with a transparent exterior design and natural lighting in colder regions.
Sun shading Low e glass provides moderate visible light transmittance, low solar power transmittance and extremely high XIR reflectance. Sun shading Low e glass is applied to areas which is hot in the summer and warm in the winter. Sun shading Low e glass is produced in a variety of exterior colors which provides the designer with many options.
