Silver-Free Low-E Glass

Silver-Free Low-E Glass is a type of low-emissivity coated glass that achieves its thermal insulation performance without using metallic silver in its coating structure.

Instead of silver, it utilizes hard semiconductor materials (such as Indium Tin Oxide – ITO) or other metal oxides deposited via magnetron sputtering.

Despite the absence of silver, it still maintains a very low surface emissivity (E-value) for effective thermal insulation.

Silver-Free = Low-E performance without silver-based functional layers

Applications

Application Suitability
Monolithic glass applications ✅ Excellent (e.g., hotel lobbies, display cases) 
Laminated glass ✅ Suitable (post‑coating lamination) 
Interior surface of IGUs (Surface #4) ✅ Ideal (part of “Dual Low‑E” configuration) 
Curtain walls (with IGU) ✅ Good (combined with conventional Low‑E)
Projects requiring heat‑bent glass ✅ Suitable (bend after coating) 
Extreme energy-saving applications ⚠️ Consider double/triple silver instead

 

Product Details

Additional information

Silver-free Low-E coated glass, referred to as silver free Low-E, is a new type of energy-saving glass, with good electrical conductivity and infrared reflection properties. High-quality float glass is used as substrate, coated with hard semiconductor oxide films by vacuum magnetron  sputtering process. Using oxide films instead of metallic silver films as functional layer,the glass has good transparency, low emissivity characteristics and thermal insulation functions, while maintaining its advantages such as high film hardness, wear resistance, and oxidation resistance etc.

Product Features

1, High visible light transmittance and excellent lighting performance;

2, Low emissivity, comparable to the ordinary silver Low-E;

3, Excellent processing performance, easy for hot bending, tempering,and laminating, no need to cut coating of edge during the hollow processing.

4. Suitable for being used as a single piece, or used as the outer surface of hollow or laminated glass;

5, Long shelf life and long-term storage.

6, Silver-free Low-E can be applied to fields such as skylight glass, curtain wall glass, and appliance glass etc.
