Fiberglass & Composite Windows


Integrity Fiberglass Windows and Doors

Integrity Windows and Patio Doors combine everything you want in a window: energy-efficiency, virtual indestructibility, low maintenance and the elegance of handcrafted wood interiors. All at a value price. Featuring Low-E insulated glass and Ultrex, a supertough polymer of glass fibers and polyester resin that is simply the most durable and energy efficient material available, with the least conductivity and response to heat or cold for a weather-tight window. That’s why it’s used in bridges, spacecraft — and now, windows and doors.

Windows and patio doors at an affordable price.
Integrity by Marvin may be the economical choice, but you won’t sacrifice quality, or features. Real wood interiors can be stained or painted to match any decor. Ultrex can also be painted to match your interior and exterior home finish. A wide range of accessories are also available, including between-the-glass grilles, hardware, and Energy-Star rated glass options. Choose from casement windows, double-hung windows, bay windows, french doors, sliding doors and more, all at a value price.
