Low-e Glass

LOW-E GLASS

Low-E (Low Emissivity) glass is a high-performance insulating glass designed to improve energy efficiency. It features a microscopic metal oxide coating on the glass surface that helps control solar heat gain and blocks harmful UV rays.

 

Low-E glass is an environmentally friendly building material.
In addition to providing energy efficiency, it helps reduce carbon emissions and supports zero-emission goals. It is an essential choice for sustainable and green building projects.
