Glass ratings and frame performance

Compare the U-factor, solar heat gain coefficient, and air leakage rating when available. Ask whether ratings apply to the exact size and configuration in your proposal.

Will new windows lower my bills?

Savings vary with weather, your heating and cooling systems, thermostat settings, and the condition of the windows being replaced. We explain product specifications without promising a fixed percentage for every home.

Installation details that matter

Your written proposal should explain the work around the opening as well as the window itself. We review existing frames, interior trim and jambs, exterior capping, cleanup, and any additional work before you order. Ask us to explain which finishing items are included and which are optional.
