When speaking of windows, particularly windows that provide form and function, energy efficiency, thermal performance, strength and style the conversation should include Inline Fiberglass windows made in Toronto, Ontario, Canada. For over 25 years Inline Fiberglass has been a world leader in the development, design and application of window and door systems. Inline was the first to introduce a full line of fiberglass windows and doors. The Sovereign FG Series of windows and doors by Inline offers the widest selection of pultruded fiberglass windows in the world. Fiberglass Pultrusion (the maufacturing process that pulls resin-soaked fibers through heated dies) offers remarkable characteristics in the product that provide superior stability, superb thermal performance and excellent strength. This material is so strong and stable that it can survive extremes in enviroments from Arctic cold to the blazing heat of the desert. Made of 60% recycled materials (mostly glass) Inline Fiberglass windows expand and contract at an extremely low rate compared to vinyl and aluminum. And since the pultrusions are utilize so much recycled glass, the marriage of the sash with an insulated glass unit provides tremendous consistency in thermal performance and longevity. Many styles, glazing options and color choices make Inline Fiberglass the most intriging window product available today and certainly the "Greenest" as well.
