The Evolution of the Double-Pane Window
Decades ago people realized that thicker panes for windows meant that the windows were sturdy. Decades later, people realized that putting a gap between two layers of glass would help decrease temperature transference from outdoors to indoors. The gap between the window pane is supported by a spacer along the window pane’s parameter which, up until barely a decade ago, would be made of metal. Due to metal’s conductivity with temperature, high-end windows now use compound elements to reduce temperature transference to an all-time low. Beyond that, the panes themselves are coated with transparent layers of temperature and element resistant compounds. Where you would expect 10-15 years from windows of the past, you can now expect 30 or more due to window pane technology and a good installer.
