Also named thermal break spacer, it is made of PP PVC, plastic materials combined with stainless steel. The thermal conductivity is approximately 0.007W/K, much better than normal aluminum spacer. The main brands we used are Alupro,Technoform,Fenzi.Lisec.

The advantage of using warm edge spacer in insulated glass:

1, Energy Saving and Heat Conduction Reduction

Warm edge spacer reduces the heat conduction of window frames, improve the insulation performance of glass edges, reduce heat loss caused by edge cold bridge effect, effectively reduce indoor and outdoor heat exchange, thereby reducing energy loss, improving energy efficiency, and enhancing the energy-saving and emission reducing effects of insulated glass, ultimately contributing to the overall value and influencing the thermal glass price.

Insulated glass with warm spacer have good thermal insulation.

2, Reduce the U value of the insulated glass.

The tradition air spacer is aluminum material ,it's with a relative high heat conductivity that the thermal conductivity is approximately 0.112W/K. Warm spacer is made of PP PVC, plastic materials combined with stainless steel. The thermal conductivity is approximately 0.007W/K, much better than normal aluminum spacer.

3, Excellent Dew Free Performance

Single panel glass outside surface always get the dew in winter cold area, this never happens to insulated glass. nsulatedglass is like a sealed cavity which boned with aluminum bar and glass with desiccant, insulated glass dew point up to -40'c ifflled with argon ,dew point decrease to -80°C.

The window glass with warm spacer never get dew in winter.

4,Has fire proof effect

Doors and windows become important escape routes when a fire occurs, therefore, the fire resistance of doors and windows is particularly important in home safety. Research shows that when heated, warm edge space can transmit only 0.15 watts of heat per second per square meter, while traditional aluminum alloy materials can transmit up to 160 watts of heat per second. The significant difference in data between these two proves the superiority of warm edge spacer in terms of fire resistance performance.

5, Extended the lifespan of the insulated glass

The warm edge spacer can reduce the stress caused by temperature changes in insulated glass . At the same time, the structure of warm edge spacer has been optimized to have higher strength and stability, providing stronger support and extending the service life of insulated glass.

The warm spacer become more popular,according to statistics, in 1990, normal aluminum edge spacer insulated glass accounted for 85% of the market share, while warm edge spacer only accounted for 15%. However, by 2000, warm edge had risen to 80%, while aluminum edge spacer had decreased to 20%.
