According to different requirements, insulating glass can be made of a variety of glass. For example, insulating glass composed of laminated glass, which has a better sound insulation effect. The hollow structure with three glass sheets and two cavities is more energy-saving. But what determines their sound insulation and energy saving effect is the 2CM (take common specifications as an example) warm edge spacer in the middle of the glass.
The origin of warm edge spacers
In the 1980s, American Edge Insulating Glass Technology Co., Ltd. successfully developed the insulating glass super spacer. The spacer does not contain any metal materials and is made of 100% polyester elastic microporous structure material. It can be applied Intermediate system of insulating glass for doors, windows and curtain walls.
Definition of warm edge spacers
It refers to a cavity composed of composite materials and stainless steel materials, used to fill the desiccant, isolate the original hollow glass, and support structural products. It is a partition material used between double-layer glass. Its purpose is to achieve the function of heat preservation and noise reduction.
The performance of warm edge spacers
1. Fire performance
As we all know, in the event of a fire, closing doors and windows is the only way to block the spread of the fire. The fireproof performance of doors and windows is directly related to the life of the person concerned. If you can carry it for a while, you can buy precious time for the person to ask for help. To put it simply, when the warm edge strip is heated, the heat passing through 1 square meter per second is 0.15 watts, while the traditional aluminum alloy passes through 1 square meter of heat per second to 160 watts. There is a big difference between that two spacers.
In winter, the temperature difference between indoor and outdoor is large, and the inside is hot and the outside is cold, and condensation will appear on doors and windows. This is because traditional aluminum spacers have very good thermal conductivity, leading to rapid loss of heat on the metal. Therefore, when the doors and windows are warm and cold, the water vapor in the air is more likely to liquefy into small water droplets, which will become dew after gathering. The warm edge spacers have low thermal conductivity, the heat energy on the metal is not easy to lose, the temperature difference between the two sides of the door and window will not be too large, and the phenomenon of condensation will not occur.
