What it is

Two panes, one sealed air space

An insulated glass unit is two or more panes of glass held apart by a spacer, with a sealed air space between them. That gap slows heat moving through the window, so your home stays cooler in summer and warmer in winter.

When a unit fails or breaks, we replace it with a new one made to fit your frame. You can also upgrade to Low-E glass while we’re there.

Glass only

New glass, same frame

If your frames are solid, there’s no need to pay for whole new windows. A new insulated unit gives you clear, efficient glass for far less.
