With the popularization of insulating glass, people's awareness of its quality, performance and some materials has become higher and higher. In recent years, the topic of upgrading warm edge spacer for insulating glass has continued to ferment. So what is the difference between warm edge spacer and aluminum spacer bar?

1. Different materials

Ordinary aluminum spacer bar is made of aluminum metal, while warm edge spacer is made of modified plastic materials such as PP, PVC, reinforced glass fiber, etc. combined with stainless steel. There are certain differences between the two. However, it should be noted that general aluminum spacer bar has different colors such as silver and black, while warm edge spacer is commonly black. Not all black aluminum spacer bar is warm edge spacer. When distinguishing, you need to judge by the material.

2. Different thermal conductivity coefficients

Relevantreference data show that the thermal conductivity of aluminum spacer bar is about 0.112W/K, while the thermal conductivity of warm edge spacer is about 0.007W/K. In comparison, the thermal insulation performance of ordinary aluminum spacer bar is slightly inferior. If there are insulating glass with higher thermal insulation and sound insulation requirements, the warm edge spacer will be more suitable.

3. Different advantages

Ordinary high-frequency welding aluminum spacer bar has good verticality, anti-distortion and smooth surface, and can maintain excellent water tightness and air tightness; warm edge spacer has excellent low thermal conductivity, which can improve the stability of insulating glass, effectively reduce the K value of the entire window, and be more energy-saving and environmentally friendly.

4. Different prices

The difference in production process and raw materials also determines that there is a certain difference in the prices of the two. In comparison, the price of warm edge spacer is slightly higher than that of ordinary aluminum spacer bar, and the price of ordinary aluminum spacer is more advantageous. Therefore, if the quotation of warm edge spacer is the same as or lower than that of ordinary aluminum spacer bar, you need to be alert to quality traps!

Warm edge spacer and ordinary aluminum spacer bar have their own advantages in terms of performance comparison and price comparison, but no matter which one, you need to choose high-quality products to achieve the corresponding application effect! Materials are not trivial. If you need to purchase high-quality aluminum spacer bar and warm edge spacer and other insulating glass materials, you can come to the source factory OYADE New Material with 15 years of production experience to have a look!
