Why does gas fill in windows?
Gas fills in multi-pane windows don’t contain moisture and doesn’t conduct heat. This means that less heat enters and escapes your home.

Why do windows break?
Causes of Broken Windows. There are several things that could cause a window or tempered glass to spontaneously break. Thermal stress. This is what happens to double-paned (or double-glazed) windows when there’s a significant difference between the temperature inside and outside of your home.
What causes broken windows?
Causes of Broken Windows 1 Thermal stress. This is what happens to double-paned (or double-glazed) windows when there’s a significant difference between the temperature inside and outside of your home. [Please link What are the Benefits of Double Glazed Windows blog when published]. 2 Large or narrow windows. Square windows distribute weight evenly. However, longer windows are exposed to more stress due to weight variances. This increases the risk of spontaneous breakage. 3 Damaged edges. Whether during the manufacturing, storing, transportation, or installation process, windows can endure scratches and chips. If it goes unnoticed at the time of installation, it can result in spontaneous breakage as the glass contracts and expands during temperature changes. 4 Improper installation. There are many factors that should be considered when installing windows, such as the pane’s dimensions, stress, and pressure. These influence the safety of the window as additional pressure on certain portions of it can increase the likelihood of breakage.
