AccuGrain Technology

The beauty of wood. The innovation of fiberglass.

Therma-Tru's proprietary AccuGrain technology gives our Classic-Craft premium entryways the look of real wood. It's nearly impossible to tell the difference. This gives you the beauty of a genuine wood door with all the benefits of a Therma-Tru fiberglass door — a door that won't warp or rot like wood.

Inspired by nature's beauty.

The unmistakable look of real wood starts with wood-grain samples taken from nature. Our experts choose select pieces of wood that have the graining and wood characteristics we want to reproduce. Only the most beautiful and stylish wood grains can become the inspiration for our Classic-Craft doors.

Brought to life by Therma-Tru's innovation.

We then use our proprietary technology to capture natural variation in each wood-grain pattern and bring it to life. With decades of experience and technical know-how, the look we can achieve with this process is so authentic that it's nearly impossible to tell our fiberglass doors from custom wood doors.

AccuGrain technology. It looks like wood. It feels like wood. No one will believe it isn't.

Available in each of the four Classic-Craft® door collections
