Fiberglass siding from Tecton Products is an innovative and ultra-durable alternative to fiber cement, vinyl, aluminum and steel. Fiberglass siding gives your home the look of freshly painted wood without the hassle of scraping and painting; fiberglass siding is virtually maintenance free.
Our design features a Water Management System that reduces mold and mildew problems by allowing water to escape and air to circulate in a plane behind the siding.
Produced in continuous lengths, fiberglass siding features clean, crisp lines with seams that butt tightly together instead of overlapping. Our joints create smooth lines for great curb appeal that sets your homes apart and our patented Durion® finish provides a variety of bold color options and exceptional weatherability.
Tecton Products offers a variety of colors for structural fiberglass siding, in 4” and 7” reveals with both a smooth finish and the best woodgrain appearance available. The system includes inside and outside corners, starter strips, finish trim and window trim to complete the exterior of the home.

*Sherwin Willams® colors are Mt. Etna, Rock Garden, Classical Gold and Earl Grey
Fiberglass siding from Tecton Products can be applied any time of the year without worry of buckles or splitting, even in the most dramatic temperature changes. It is resistant to oxidation, rust and the corrosive effects of harsh coastal environments making it the optimal choice for homes in any climate.
