Why use toughened glass panels for broken bridge aluminum windows?

Broken bridge aluminum doors and windows refers to the use of heat-insulated broken bridge aluminum profiles and insulating glass, which has the functions of energy saving, sound insulation, noise prevention, dustproof, waterproof and so on. The thermal conductivity coefficient K value of aluminum bridges and windows with broken bridges is less than 3W/㎡·K, which is less than half of the heat loss of ordinary doors and windows, and the sound insulation is more than 29 decibels.

Many consumers only care about the price when buying aluminum doors and windows with broken bridges, ignoring a lot of configuration items, especially glass matching, often thinking that glass matching does not make much sense. In fact, the choice of glass to a large extent determines whether the windows in the home are thermally insulated.

Why use toughened glass panels for broken bridge aluminum windows?
Because the windows used to be plastic-steel windows, the material was plastic, and there was a buffer strip between the frame and the glass. The glass rarely cracked. The broken bridge aluminum window is different. The material is a metal aluminum alloy material. The glass and the metal are in direct hard contact. At the same time, the elastic tension of the glass glue will cause the glass to split itself without the external force. Although this is not the case for every piece of glass, the probability of self-cracking in broken aluminum glass is much greater than that of tempered glass.

From a safety point of view, toughened glass panels have higher strength and better security than ordinary glass, especially the windows at home are floor-to-ceiling windows. If the glass is large glass, you must choose tempered glass. Tempered glass is especially suitable for those with children and the elderly at home. The tempered glass bursts into small particles and does not hurt people.

What is the relationship between broken bridge aluminum window glass and sound insulation?
We know that for a door and window, the material frame of 30% of the area, and 70% of the area is glass area, so a large part of the quality of the window insulation and sound insulation is determined by glass. The conventional broken bridge aluminum window must first choose tempered glass. Secondly, qualified owners can choose double-layer insulating glass with Low-e function. This glass configuration can greatly improve the sound insulation and thermal insulation effect of windows.

According to some data, Low-E glass can save 60%-70% of energy per year than ordinary glass. In the same west-facing house, if you use ordinary glass, you can use 135 kWh a year, and if you use Low-E energy-saving glass, you only need 54 kWh a year, and use 81 kWh less each year.
