High Quality Low-E Reflective Glass Windows

High Quality Low-e reflective glass windows Product Description Low Emissivity Glass (also Low-E glass) is coated with a film  system composed of multiple layers of silver, copper,tin and other metals or their compounds on the surface of the glass. The product has high transmittance to visible light, high reflectivity to infrared, and good heat insulation. Performance, mainly used in construction and vehicles, ships and other vehicles.  Maximum Size2500*60000mmMinimum Size300*300mmmThickness5-25mmColourclear, green, crystal grey, European grey, ultra white, etc.Longlass Low Emissivity Glass Features:Excellent thermal performance1. Low-E glass manufacturing doors and Windows of buildings, can greatly reduce the radiation caused by the transfer of indoor heat to the          outdoor, to achieve the ideal effect of energy saving.2. If low-E glass is used, the amount of fuel consumed for heating can be significantly reduced due to the reduction in heat loss, thus reducing the  emission of harmful gases.3..Low-e glass can meet the requirements of winter and summer. It can not only heat preservation and heat insulation, play the effect of environmental protection and Low carbon.Good optical propertiesThe visible light transmittance of low-e glass varies theoretically from 0% to 95% (6mm white glass is difficult to achieve), and the visible light transmittance brepresents the indoor daylighting.Product ParametersSingle Low-e GlassProductVisible Light(%)Solar Direct(%)Shading Coefficient (s.c.) NFRC100-2010Solar Heat Gain Coefficient (SHGC) NFRC 100-2010NFRC U-Value W/m2.K NFRC 100-2010European U-Value W/m2.K (EN 673)TransmittanceReflectance (Out)Reflectance (In)TransmittanceReflectance (Out) Summer Winter6LEN-1(2#)+12A+672111146170.610.531.861.851.86LGE-l(2#)+12A+671101246180.610.531.861.851.86LGE-ll(2#)+12A+661111240140.550.481.971.941.96LGE-lll(2#)+12A+654201034210.470.411.841.841.86LGE-IV(2#)+12A+646221029240.410.361.821.821.86LGE-V(2#)+12A+645291228310.390.341.751.761.76LGE-VI(2#)+12A+638291322340.320.281.701.731.76LGE-VII(2#)+12A+642271027270.390.341.861.851.86LETB-150-1(2#)+12A+645241028270.400.341.791.801.86LETB-160-1(2#)+12A+652221032250.450.391.841.841.86LETB-170-1(2#)+12A+664101140160.540.471.891.871.96LETS-150(2#)+12A+643311226310.370.331.771.781.86LETS-150-1(2#)+12A+646261030250.420.371.871.861.86LETS-139(2#)+12A+636291023290.330.291.821.821.86LYPE-140(2#)+12A+635341420360.300.261.671.711.76LYPE-152(2#)+12A+649201031230.440.381.841.841.8  Double Low-e Glass  ProductVisible Light(%)Solar Direct(%)Shading Coefficient (S.CJ NFRC100-2010Solar Heat Gain Coefficient (SHGC) NFRC 100-2010NFRC U-ValueW/m2.KNFRC 100-2010TransmittanceReflectance (Out)Reflectance (In)TransmittanceReflectance (Out)Summer Winter 6 LGD1-1(2#)+12A+669131532330.430.371.601.656 LGD1-2(2#)+12A+667111330260.430.371.601.656 LGD2-1(2#)+12A+662151730250.400.351.651.696 LGD2-2(2#)+12A+660101126240.380.331.591.656 LGD2-3(2#)+12A+660101226280.370.321.561.626 LGD3-1(2#)+12A+655181821350.310.271.621.676 LGD3-2(2#)+12A+654161824260.360.311.571.636 LGD4-1(2#)+12A+650151322300.320.281.641.696 LGD4-2(2#)+12A+650252321300.290.251.581.646 LGD5-1(2#)+12A+645141220310.290.251.641.686 LGD5-2(2#)+12A+644332217410.260.231.531.616 LGD5-3(2#)+12A+643211418390.270.231.601.656 LGD6-1(2#)+12A+640241416380.240.211.631.676 LGD6-2(2#)+12A+640143120230.300.261.551.626 LGD6-3(2#)+12A+639143119190.300.261.611.66The above data are calculated by WINDOW6.3 developed at Lawrence Berkeley National Laboratory,except for having been given clear indication of standards.
