It was nearly 30 years ago when Comfort Line introduced the first fiberglass window ever made. Recognizing the performance advantages of pultruded fiberglass, Comfort Line’s leadership took bold and innovative steps to be the first to apply this high quality, high performance material to window and door frames.
Our EcoFibre line not only introduces the first fiberglass window frame, it also introduces the first fiberglass sliding patio door to the US market. Our patio doors top the list in industry standards with recognition as the Patio Door of the Future.
We continue our innovative approach to windows and doors even to this day by bringing strength, energy savings, and good looks to all of our products. Our unique partnerships with industry leaders allow us to offer you the very best energy efficiency in glass, more frame color choices than any other manufacturer, and the greatest strength of materials.
