High energy saving 24mm warm edge spacer insulated glazing warm edge windows glass factory in china

Insulated glass has become one of the most popular types of glass windows. There are several types IGU glass, but today we are talking about warm edge spacer windows. It has a high energy saving effect, meanwhile reducing noise, and minimizing the amount of infrared and ultraviolet, without losing the amount of light into your house.

What is warm edge spacer insulated glazing?

Warm edge spacer insulated glazing is using warm edge spacer bars to insulate the sealed glass panes. Traditionally insulated glazing spacer bars are aluminum, which is highly conductive to heat and allows more heat to pass through, decreasing thermal insulation performance. When it’s cold outside and warm inside, the heat in the home escapes through the spacers, so the edges of the windows are colder. The heat loss means more heating is needed to keep a comfortable indoor temperature, compared to traditional aluminum spacers, it offer superior insulation performance.
