Why Fiberglass

Superior Thermal Performance and More Beautiful Views

  • Energy Efficiency

    The best performance

    Fiberglass windows are the most energy efficient windows on the market. Superior thermal performance means less money spent on heating and cooling your residence or workplace.

  • Durability

    and beauty too

    Fiberglass window’s incredible strength results in lower profile frames. At almost eight times stronger than PVC, fiberglass windows bring more glass surface with superior durability.

  • ALL-WEATHER WINDOWS

    All weather Windows

    Fiberglass frames are comprised of 65% – 85% glass fibers. The resulting stability means that no Arctic blizzard cold or blistering desert heat can affect the performance of fiberglass.

  • Green Friendly

    Low-impact

    The pultrusion process consumes less energy than all other types of frame materials, making fiberglass the most environmentally friendly of all window frames.
