How do we make Fiberglass doors look like real wood?
We use a special process know as Accugrain. Accugrain is a door casing process that uses multiple dies to product 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. They then enhance the wood door using proprietary technology to enhance the natural graining depth on the wood before casing. Then, with the graining technology, the final product undergoes multiple casting. This process, called random depth graining, combined with the multiple dies to product different graining types, makes our fiberglass doors virtually indistinguishable from real wood doors.
