Insulated glass is simply two pieces of glass with a sealed airspace between them. Combined with a
wood or vinyl frame, this creates a window that far outperforms most of what was installed before the
energy crisis of the '70s. For even greater insulation, you can choose high performance options as
low-emissivity glass (shortened to low-E - think energy efficiency), which is a very thin coating put on the
glass that reflects heat while maintaining the visibility of clear glass.

Low-E glasses are available today, and they are geared for hot climates like Texas.

This question comes up quite often, as many times a double pane window
only has one broken piece of glass.

Also customers want to know if we can take apart an insulated unit, clean it to remove fogging and
put it back together. The answer to either of those questions, is yes, these things can be done. But is
it practical?

Not even close.

The labor involved in either of these scenarios would be far greater than just recreating the entire
unit. Each unit has a type of condensation control material between the panes, to keep the glass
from fogging up under normal conditions, ie: there has been no trauma to the unit, such as a
cracked pane or tension on the frame, which often happens when a house settles.

With heat on one pane of glass and cold on the other, this condensation control material stops from
happening, what normally happens under these conditions—condensation—or fogging in between
the glass. Once a pane is cracked or broken, or in any way compromised, this condensation control
material absorbs all the moisture it can—immediately—and once this happens it is no longer useful.
If a new piece of glass is simply put on the unit then it will begin to fog up immediately as there is
nothing to prevent it.
Can an insulated glass window be repaired by just
replacing one damaged piece of glass?
