Item Commercialization of a Residential Panel Door (1995-02): Semi-Annual Progress Report(University of Minnesota, Duluth, 1995-02) Donahue, Patrick KThe project's goal is to continue technical and business development efforts to facilitate the commercialization of a veneered residential wood door designed with an engineered substrate and an engineered veneered door skin. Specifically, to continue product performance testing. This task will be accomplished by combining business expertise of Lexington Manufacturing of Coon Rapids, Minnesota, and the product development skills of the Natural Resources Research Institute (NRRI) scientists. The successful completion of this work will posture Lexington Manufacturing closer to expanding their business with a veneered panel door product line.Item Commercialization of a Residential Panel Door: Final Report(University of Minnesota Duluth, 1999-10) Donahue, Patrick KItem The Development and Commercialization of a Residential Panel Door (1994-03): Semi-Annual Progress Report(University of Minnesota, Duluth, 1994-03) Donahue, Patrick KObjective: To facilitate the commercialization of a residential wood door using computer numerically controlled (CNC) routing and engineered veneered overlay technology.Item The Development and Commercialization of a Residential Panel Door (1994-10): Semi-Annual Progress Report(University of Minnesota, Duluth, 1994-10) Donahue, Patrick KObjective: To facilitate the commercialization of a residential wood door using computer numerically controlled (CNC) routing and engineered veneer overlay technology.

The test results demonstrate the effect of thermal treatment on the physical and mechanical properties. The biological durability results, tested according to American Wood Protection Association(AWPA) standards, suggest one hardwood (white ash), and two softwoods (balsam fir and eastern hemlock) may meet minimum service life thresholds for AWPA above-ground-use classification.
