Low-E Glass

Our Low-E glass allows more sunlight in the bridge deck or desired area to enter, without altering its natural colour. It improves insulation against heat transfer, sound transmission and reflects infra-red rays.

The vacuum sputtering process coats glass surfaces with several layers of different materials. Among these, a silver layer effectively reflects infrared rays while maintaining excellent thermal performance.

Beneath the silver layer is an anti-reflective tin diooxide (SnO₂) base layer that increases the transparency of the glass. Above the silver layer is an isolating nickel-chromium (NiCr) alloy coating. The main function of the top anti-reflective tin diooxide (SnO₂) layer is to protect the other coating layers. This product offers the high transparency, low reflectivity, good thermal insulating and energy-saving properties required in modern vessels.

Benefits:

• Natural color of glass
• Highly transparent to visible light (wavelength 380nm ~780nm), will not produce significant glare problems caused by high reflectance of visible light.
• Natural illumination: 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.
• High reflectance: Relatively high reflectance of infrared radiation (wavelength 780nm~ 3,000nm). In particular, reflects nearly all long-wave infrared (wavelength over 3,000nm). Blocks the entrance of large amounts of heat, and leaves interior comfortably cool in the summer and warm in the winter.
