Insulated glass is produced by placing a spacer between two panes of glass and sealing the edges of the unit. The air is trapped between the two pieces of glass and acts as an insulator to reduce the rate at which heat and cold can travel through the unit. Insulated glass units last for a very long time, but the seal between the two panes of glass some times do fail. This causes the inner surface between the two pieces of glass to fog up. This of course does not look good but more importantly an insulated unit with a broken seal looses its insulating properties and temperature transfer between the two sides of the glass happens more readily. If this happens, in most cases only the glass portion of the window can be changed, leaving the frame intact. In case of an accident where only one pane of the glass breaks, the entire insulated glass unit needs to be replaced. Replacement of an insulated glass unit is normally not a DIY project and requires experience. Here at Pure Showers Inc., we can measure, fabricate and install your insulated glass unit in record time.
