Break-In Resistant Wood Panel Door

Agency:

Forest Service

This invention is a wooden panel door reinforced against attempted break-in by layers of fiberglass mat and decorative wooden facing strip bonded to the doorjamb and stiles. The stiles and doorjamb are constructed from wood with grain that runs primarily in a single direction, and reinforcing these stiles and doorjambs against impact can be achieved by bonding them to a fiberglass mat, which contains fibers running in transverse directions. The result is a substantial increase in the strength of a wooden panel door without unduly increasing the cost of the door or diminishing its aesthetic qualities.
