  • Insulated door assembly with low thermal deflection
    Patent number: 6740279
    Abstract: Compression molded pigmented door skins fabricated by compression molding a pigmented, curable, unsaturated polyester sheet molding compound containing a co-curable unsaturated monomer, a low profile additive, and a microvoid-reducing thermoplastic polymer, exhibit uniform stainability while maintaining a low linear thermal coefficient of expansion. Such door skins are suitable for preparing wood grain textured exterior insulated doors which exhibit minimal thermal deflection when exposed to interior/exterior temperature differentials, even at eight foot door heights. The doors may be stained without first applying a seal coat.
    Type: Grant
    Filed: January 4, 2001
    Date of Patent: May 25, 2004
    Assignee: TT Technologies, Inc.
    Inventors: Kenneth J. West, Greg W. Scheffel, G. Daniel Templeton, Eugene R. Davis, III
