What are the advantages of fiberglass door systems over wood and steel doors?
Unlike wood doors, fiberglass won't dent, crack, split or splinter. Unlike steel doors, fiberglass
won't dent, rust or warp, either. Fiberglass also resists shrinking and swelling with temperature
changes, allowing the finish to last three times longer than on a wood door. The solid polyurethane
foam core offers five times greater insulation value than wood doors.
Why should I select a Therma-Tru Entry Door System?
Therma-Tru is the market leader and innovator in fiberglass door technology. Our fiberglass doors
are more durable and energy-efficient than wood or steel doors. And because of our commitment
to quality, our lines of fiberglass doors are backed by full-system warranties--the best in the industry.
What types of fiberglass entry door systems does Therma-Tru offer?
There are three lines of fiberglass entry doors to fit any budget: Classic-Craft, Fiber-Classic and
Smooth-Star Door Systems.
Classic-Craft® Fiberglass Doors
Beautifully detailed, our Classic-Craft doors give you all the premium touches you'd expect to find in the finest wood doors, plus more. Their durable fiberglass surface features a rich red oak grain, but unlike wood doors, they won't split, crack, dent or warp. They feature deeply detailed embossed or raised panels, full-mortised brass hinges and solid oak square edges. A solid polyurethane foam core offers five times greater insulation than wood doors. Plus a wide wood lock stile extends the full length of the door, adding security and stability. They can be stained in all the popular stain colors with the Therma-Tru Finishing System, or painted to match any decor. Best of all, the entire door system is backed by a lifetime-limited warranty.
Fiber-Classic® Fiberglass Doors
Fiber-Classic doors are far superior to wood doors, yet priced considerably less. They give you the look and feel of wood without the disadvantages - the fiberglass surface resists damage - no splitting, cracking or warping. They insulate five times better than wood doors due to a solid polyurethane foam core. And, like Classic-Craft doors, they can be stained to look like wood or painted, if you prefer. All Fiber-Classic door systems also carry a lifetime-limited warranty for as long as you own your home.
Smooth-Star® Fiberglass Doors
Smooth-Star fiberglass doors are a perfect alternative to steel doors. When comparing Smooth-Star fiberglass doors to steel the differences are dramatic - better looks, better feel, better performance and twice the warranty of steel doors. Smooth-Star's tough surface won't dent, rust, split or warp, even during construction and years of day-to-day traffic. Backed by a 20-year limited warranty, they feature tough compression-molded fiberglass, a solid polyurethane foam core and a smooth, paint-grade plus surface. And they're comparably priced to steel!
