Modern building on the functional requirements of the glass can be attributed to energy efficiency, decorative, comfort and so few parts. Pursuit of large area lighting glass design has become a trend, which is energy-saving building design contradictory sexual orientation. The use of transparent glass the summer heat too much sunlight into the room, they can not stop the indoor winter heat spillover maintain proper indoor temperature at the cost of air conditioning or heating energy consumption has increased substantially. To resolve this contradiction through the most effective way is to use coated or hollow glass products processed replace the ordinary transparent glass.
Low-E glass not only has a very good energy efficiency, with a wide range of lighting, soft light quality, to avoid the generation of light pollution, and create a good ecological environment, with multi-colored decorative effect, thus becoming the product of choice for architectural design .
Low-E glass for energy efficiency is reflected in its solar heat radiation shielding - namely insulation, leakage barrier for heating - ie heat two aspects. Due to the use of different geographical and design requirements, Low-E glass is divided into shade, high permeability two series.
High Permeability-type Single Silver Low-E glass
o High visible light transmittance - appearance of good permeability, indoor natural lighting effects.
o High solar transmittance - solar heat radiation through the glass and more glass shading coefficient Sc ≥ 0.5.
o High infrared reflectivity - lower heat transfer coefficient U-value, excellent thermal insulation properties.
o Its insulation Feature makes it suitable for cold northern regions, winter allows solar heat radiation into the interior in order to increase the indoor heat, and indoor heating, household appliances and human body emits far infrared heat reflected back indoors, effectively reduce the energy consumption of heating.
o Its high transmittance Feature makes it suitable for high-permeability regardless of geographical design of the building, the building transparent, prominent natural light.
Single Silver Low-E glass
o Effectively reduce the transmission of ultraviolet rays, thus preventing UV damage to the skin, interior furniture, fabrics, artwork fade.
o Low-E glass must be made of a hollow or a hollow composite products to use, with good thermal insulation, thermal insulation properties.
o Moderate visible light transmittance - indoor lighting to create the right effect on the outdoor line of sight has some shielding.
o High infrared reflectivity - heat transfer coefficient U value is low, limiting the background of the summer outdoor thermal radiation into the interior.
As Low-E glass insulation, heat retention Feature, it applies not only to the southern region, but also for the northern region, which can effectively block summer solar heat into the room, and the reflection from the far-infrared heat radiation outdoors. While some winter it limits the entry of solar energy, but it will block more of the sun in summer heat into, the winter the summer solar strength of only about 1/3, thus the insulation performance is not affected. In fact, on the north of Shenyang area in winter and summer energy-saving effect of comprehensive simulation calculations show that the energy saving effect is far better than the high permeability type Low-E glass.
Sunshield Low-E glass has a variety of colors and reflections moderate light transmittance, it has a richer decorative effect and outdoor sight shielding effect, this Feature give it a wider range of applications, and deep favorite architect.
Double Silver Low-E glass
Double silver Low-E glass is an advanced Low-E glass, belonging Sunshield Low-E glass, which highlighted the glass on the solar heat radiation shielding effect of the glass high light transmittance and solar heat radiation, low permeability sexual cleverly combined, in addition to its more general feature Low-E glass, but also has the following two characteristics.
o Higher rates of visible light through - to maintain a high visible light transmittance, ensure good natural lighting.
o Low solar transmittance - effectively limit solar heat radiation through especially through the near-infrared thermal radiation.
o In the case of the same visible light transmittance, than normal Low-E glass having a lower solar transmittance, which has a lower shading coefficient Sc. In other words, it minimizes the sunlight filtered into cold light source, to address the high visible light transmittance and low solar transmittance not take into account the contradictions, for the pursuit of the appearance of the permeability of energy saving design provides protection. The Low-E glass is more suited to our climate characteristics, and its integrated energy-saving effect is far better than ordinary Low-E glass.
Bent Low-E glass
Common Low-E glass coating after completion can not be bent, steel and other heat treatment process, which makes extensive use of Low-E glass to promote and facilitate the development of building energy efficiency has been greatly restricted. The company meets China's national conditions and the level of economic development, research and development in a timely manner using new materials, and can produce bent Low-E glass, architectural curved glass design fully meet the need to use, has been widely used at home and abroad many large buildings, as the popularity of Low-E glass to use laid the foundation for China's building energy career to make a contribution.
o After the coating can be achieved bending, steel and other treatment.
o Low-E glass with ordinary thermal properties of light and good energy saving effect.
Low-E glass composite product range
o Composite glass:And other low-emissivity glass composite coating can be made after the Hollow Glass, Low-E coated steel Hollow Glass, semi-tempered low-E coating Hollow Glass, as well as multiple combinations of composite products.
o Color:With colorless, transparent, light blue, gray, light gray, blue-gray color, and there are different shades of each color tint, color diversification;
o Naturally, each suitable for its elegant style, designed to meet the different needs.

Meet GB/T18915.1-2002 "coated glass" national standards
o Special noise insulation requirements: Low-EHollow Glass in filling argon (Ar), can further reduce the heat transfer coefficient U-value, enhanced noise performance.
o Prevention glass thermal stress cracking: Elected solar absorption close to or more than 70% of glass products, it is recommended should be done toughened glass or semi-steel processing, to enhance its resistance to thermal shock, and to prevent the glass thermal stress cracking.
o Color choices: Performance parameters noted in the table in the outdoor natural color of the glass reflection sky background color, background sky changes observed glass reflection color will be different, so to be taken when selecting multi-faceted, multi-angle observation is due.
