Meet the very first fiberglass front door — the door that revolutionized an industry. Therma-Tru’s Fiber-Classic® Oak door changed how doors are made, and still sets the standard for today’s fiberglass entry doors.
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.
