Fiberglass Replacement Windows
Fiberglass windows and patio door systems provide the perfect balance between form and function. Fiberglass replacement windows have incredible strength and thermal efficiency. WInrepco, Inc. has been serving Northern VA, including the counties of Loudoun, Fairfax, Clarke, Frederick, Warren, Prince William, Arlington, Alexandria, Warren, Shenandoah County and surrounding areas since 1983. If you are not in our service area we will gladly refer your request to Comfort Line Windows for a quality dealer in your area.

Fiberglass windows have the highest R-value (resistance to heat loss) of all framing materials — better than wood, better than vinyl, better than aluminum. Fiber glass windows and doors also gives you superior durability because of the superior dimensional stability and inherent strength of pultruded fiber glass.
Unbeatable strength. Comfort Line has manufactured and supplied windows and patio doors for the building products industry since 1959. In 1964 Comfort Line pioneered the use of vinyl for storm windows and storm door fabrication. Pultrusions technology revolutionized the window industry again in 1988.
Unlimited Options to match your decor. This window system provides the best of both worlds: a frame and sash constructed of pultrusions fiberglass with real oak veneer applied to the interior. Windows are available with Oak Veneer interior frames and in exterior and interior solid color finishes. Custom colors are also available.
Time tested for durability. Our fiberglass windows are indestructible by the elements. With beauty and comfort in mind, we have taken fiberglass of superior strength and designed a window system that offers a lifetime of maintenance free operation.
Complete product line for your home. Double-hung, Sliders, Picture, Sidelight, Casement, Awning, Specialty Shapes including Half Rounds, Circles and other geometric shapes are available from COMFORT LINE in the FIBERFRAME Product Group. Bay and Bow configurations are also available.
