Wood window and door manufacturers operate production facilities where raw lumber and engineered wood components are cut, shaped, assembled, and finished into window units, door units, sash, frames, and related millwork. Operations typically involve heavy woodworking machinery, adhesives, coatings, and finishing chemicals. Products are generally sold to builders, contractors, distributors, or home improvement channels rather than directly to end consumers.
