FIBERGLASS, AS A BUILDING MATERIAL, IS NOTHING NEW

Fiberglass has been floating boats and strengthening ladders for years. In the window industry, however, it’s the latest addition to a range of finish options.

Fiberglass windows currently comprise about 4% of the market and the percentage is growing each year.
