Our High-Performance Window System:
Energy Efficiency. Our high-performance vinyl (UPVC) replacement windows are energy-efficient to reduce wasted energy. That protects the environment and saves you money.
Comfort. And, your home stays cooler in the summer, and warmer in the winter, for year-round comfort.
Light. At the same time, bathe your home in cheerful bright light.
The Doers Difference. Most windows take an Insulated Glass (IG) unit and build a sash around it. We incorporate the IG unit, with the spacer, and directly glaze the lites of glass to both sides of the sash.
This greatly enhances structural and thermal performance - a true industry breakthrough! You get the strongest and best performing window in America!
