Replace Insulated Window Glass

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.

This application is mostly used in situations where the glass unit acts as a barrier separating the indoors from outdoors. Almost all of the glass units used on the outside walls of residential and commercial units are insulated. This reduces temperature transfer and helps save energy. Substitute one of the two pieces of glass with a low E Glass and you dramatically slow heat transfer even further.

Insulated Glass

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 in Dulles Glass and Mirror, we can measure, fabricate and install your insulated glass unit in record time.

We understand that sometimes you need more information before you are ready for scheduling a project and we are here to help. Please provide us with the following information about your window and we can help you price the project to some extend.

  • Size of the glass within the frame
  • Location and accessibility of the unit (first floor or second floor etc..)
  • Presence or absence of grids. This is the decorative plastic piece inside the unit.
  • Overall thickness of the insulated glass unit.
  • Finally, we need to know if the glass is tempered. In most residential houses insulated glass units are not tempered unless they are on a door or next to a door.
