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 oxide (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 oxide (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 of modern architectural glass and green building design!

Benefits：

1. Approaches the natural color of glass.

2. Highly transparent to visible light (wavelength 380nm ~780nm), will not produce significant glare problems caused by high reflectance of visible light.

3. 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.

4. Relatively high reflectance of infrared radiation.  Blocks the entrance of large amounts of heat, and leaves 　interior comfortably cool in the summer and warm in the winter.

Applications：Architecture, facade materials, etc.

Notes on Design and Glazing：In tropical or subtropical areas, the Low-E coating should be positioned on #2 for heat insulation surface (facing inward from outside the building), while positioned on #3 surface for keeping interior warm in cold areas.

5. Other glass as mirror, rolled glass, super clear glass, etc.
