Insulator

Graef’s newest window line, the Insulator, has made choosing a window system for your home easier than ever. No matter where you live, no matter the type and style of your home, the Insulator family of products offers just what you are looking for.

We made sure when we designed the Insulator to include the features requested by homeowners across the country. Fusion-welded corners, 7/8” insulated glass, and fully weather-stripped sashes combine to provide outstanding performance. As a result of our modern design, drafts are reduced, disturbing outside noises are quieted, and room temperatures are efficiently maintained.

You and your family will enjoy year-round comfort, long-lasting performance, low maintenance, and energy savings. All Insulator products are warranted by Graef’s Standard Silver Warranty with availability of the optional Gold Warranty.

Each window is custom made to fit the window opening in your home. You can choose from a wide selection of shapes and styles to give a distinct personality and look to your home. Traditional double-hungs, two and three lite sliders, picture windows, and shapes create just the look you want in your home.

Availabe Types: Double Hung, Sliders

Thermal-Weld

Graef’s traditional Thermal-Weld line assures you of a lifetime of quality and performance. Energy efficiency, product design, and solid quality construction are what make the Thermal-Weld window series unmatched in our industry. The quality is subtle but ever-visible in the Thermal-Weld family. Our exclusive Magna-seal, much like the air-tight seal on a refrigerator door, creates the ultimate in energy efficiency and noise reduction. Thermal-Weld's coved interior sash and beveled exterior frame create an elegant moulding-like appearance, both inside and out. The stainless steel sash coil balance system will never need maintenance, assuring you a lifetime of trouble-free operation. Many color and glass options are available to create the window that suits your décor perfectly. Of course, Graef continues to offer its excellent warranty options for your peace of mind.
