Entry Door Products
American Style Collection™ fiberglass entry doors were inspired by early 1900s residential architecture. The collection complements many popular home designs, including Arts and Crafts, Bungalow, Cottage and Colonial Revival styles.
Made with our patented AccuGrain™ technology, you get the look of high-grade wood with all of the durability of fiberglass. The exterior doors in this collection have the look and feel of a real wood front door — with solid wood square edges, architecturally correct stiles, rails and panels. Unlike genuine wood doors, they resist splitting, cracking and rotting.

Our original vision was an entry door that would not crack, split, splinter, or warp like wood. The result? Therma-Tru’s Fiber-Classic fiberglass entry door that’s durable, stylish, economical and most preferred by builders and remodelers.
Get the look of fine painted wood and the strength of steel with a front door from the Smooth-Star® Entry Door Collection.

This perfectly stylish yet rugged fiberglass front door resists the dents and dings from day-to-day traffic, and will never rust or corrode.
