Buying a Fiberglass Composite Door

Where a door will be exposed to weather or particularly harsh or humid climates, a fiberglass- composite door is a smart choice.

These doors realistically imitate the look of wood, thanks to a combination of molded wood grain texturing and the fact that they can be stained to match most popular woods such as oak, cherry, and walnut.

Therma-Tru

Fiberglass entry door fuses technology with beauty.

Fiberglass doors are sold as single units or complete entry systems. For example, Therma-Tru’s Classic-Craft door includes oak-over jambs, a variety of glass doorlite styles, oak adjustable sills, security strike plates, and a lifetime limited warranty.

Because they’re quite durable and maintenance-free, fiberglass-composite doors tend to have long limited warranties. Pease Doors, for example, backs its doors for as long as you own the house. Because a door’s longevity depends on installation and exposure, this type of warranty is usually only available on a complete entry system.

A fiberglass door isn’t entirely fiberglass. The durable surface of compression-molded fiberglass covers a framework of wooden stiles and rails, including wood edges. The framework’s voids are filled with CFC-free polyurethane foam insulation.

Pella

Fiberglass doors are generally less expensive than wood. Expect to pay about $200 for a 3-foot-by-6-foot-8-inch paneled door without glazing or hardware. The other accessories, however, such as glazing and hardware, cost the same no matter what material the door is made from. Fully loaded, a fiberglass entry system can reach $4,000, just like a wood door system.

Many fiberglass door manufacturers also make steel doors. These makers include Castlegate Entry Systems, Pella, Ceco Doors, Stanley Door Systems, Peachtree Doors, and PermaDoor.
