The Beauty of Wood in Fiberglass Innovation
Therma-Tru’s proprietary AccuGrain™ Technology has given our Classic-Craft® line of entry doors the genuine, authentic look of traditional wood doors.
What is AccuGrain
AccuGrain is a door casting process that uses multiple dies to produce different graining types to cast the appearance of real wood into our fiberglass doors. At a high-level, the process starts with building a wood door using select pieces of wood that have the graining and wood characteristics we want to reproduce. We then enhance the wood door using proprietary technology to enhance the natural graining depth on the wood before casting.
Then, with the graining technology, the final product undergoes multiple casting. This process, called random depth graining, combined with the multiple dies to produce different graining types, makes our fiberglass doors virtually indistinguishable from real wood doors. This gives you the beauty of a wood door with all the benefits of our fiberglass doors — doors that won’t split, crack or rot like real wood.
Available in each of the four Classic-Craft® door collections
