Yes. Therma-Tru fiberglass doors with a wood-grain texture are designed specifically for staining and can be finished to closely replicate the appearance of a natural wood entry door. Smooth fiberglass and steel doors are designed for painting. Therma-Tru provides staining guidelines and recommended finishing products for each door texture to achieve the best result.
Therma-Tru door systems are available as pre-hung units complete with the frame, weatherstripping, and hardware preparation. This is the standard format for new construction and most replacement applications. Confirm with your local Windsor Plywood location whether slab-only options are available for situations where only the door panel needs to be replaced.
Therma-Tru offers a limited lifetime warranty on their fiberglass door slabs against defects in material and workmanship under normal residential use. Glass and finish components carry separate limited warranties. Specific warranty terms vary by product line and must be registered after purchase.
