Qingdao Huayi Arts & Crafts Co. Ltd

Model Number: JTLG1501652-#2787 Brand Name: JT Key Specifications/Special Features: Low-E glassLow-E glass refers to a series of high-performance low-emissivity productsVacuum sputtering process coats glass surfaces with several layers of different materialsAmong these, a silver layer effectively reflects infrared rays while maintaining excellent thermal performanceTypes of product:

Single low-E glass (SLE)

Double low-E glass (DLE)

Low-E-sun layer glass (LES)

Ti-based low-E glass (TLE)

Benefits:

• Approaches the natural color of glass
• Highly transparent to visible light (wavelength 380-780nm), will not cause significant glare problems due to high reflectance of visible light
• Allows most sunlight in the visible range to enter without altering its natural color Provides excellent natural illumination and saves energy by reducing the need for artificial lighting
• Relatively high reflectance of infrared radiation (wavelength 780-3000nm)
• In particular, reflects nearly all long-wave infrared (wavelength over 3000nm), blocks the entrance of large amounts of heat and leaves interior comfortably cool in the summer and warm in the winter

Specifications:

• Thickness: 3 to 19mm
• Maximum size: 3300 x 6000mm
• Minimum size: 300 x 300mm
• Low-E insulating glass maximum size: 3300 x 4880mm
• Notes on Design and Glazing
• Low-E glass cannot be used as a single glazing and must be sealed or processed into insulating glassunit within a very short time as the metallic oxide coating is prone to undesirable reactions onceexposed to air
• Emissivity of low-E insulating glass is 0.02 to 0.11, while that of uncoated glass is 0.84
• In tropical or subtropical areas, the low-E coating should be positioned on #2 surface (facing inwardfrom outside the building), while positioned on #3 surface in temperate areas
• To avoid deterioration and fogging of the glass due to water accumulation, the metal holding framesmust be well drained
• Low-E glass designed for laminated glass unit will be under a greater U-value and poorer thermalinsulating capability
• To identify the coating surface of low-E glass, aside from looking for the mark, use a cigarettelighter to inspect the surface of the glass
• Reflection of the flame on ordinary glass surface will beyellow, while pink or blue on Low-E glass surface
