Abstract
Various wood composite designs are disclosed for use in door and window systems, incorporating strengthening sheets to inhibit bowing or cupping.
Claims25
A structural component for framing a door or window comprising
- An elongate wood composite member having a rectangular cross-section including a solid wood component and a low-grade wood component comprising at least one of the following materials:
- finger-jointed stock, MDF, OSB, LVL, and plywood;
- each of the solid wood and low-grade components having a substantially triangular cross-section, thereby defining a diagonal interface between the two components, and
- a strengthening sheet material secured in the diagonal interface.

A structural component for framing a door or window comprising
- An elongate wood composite member having a rectangular cross-section including a solid wood component and a low-grade wood component comprising at least one of the following materials:
- finger-jointed stock, MDF, OSB, LVL, and plywood;
- wherein the composite member has first and second corners defining a diagonal plane substantially parallel to a diagonal interface between the solid wood and low-grade wood components, and
- a strengthening sheet material secured in the diagonal interface between the solid wood and low-grade components.
1 more element
A sash component for a double hung or sliding window product comprising
- an elongate wood member having a first side, and a second side perpendicular to the first side, a milled profile being configured opposite the first and-second sides for supporting a sheet of glass and stopping another window component, wherein each of the first and second sides is substantially covered by a strengthening sheet.
A sash component for a double hung or sliding window product comprising
- an elongate wood member having a first side, and a second side perpendicular to the first side, a milled profile being configured opposite the first and second sides for supporting a sheet of glass and stopping another window component, wherein the wood component is formed of a solid wood portion and a low-grade wood portion,
- a strengthening sheet interposed between the solid wood portion and the low-grade wood portion, the strengthening sheet being oriented substantially perpendicular to the first side of the wood member, and
- a veneer sheet at least partially covering the first side of the wood member.
A jamb component for a window or door comprising
- an elongate wood composite member having a back side and an exposed side, a stop portion having a stepped-up inner surface defined on the exposed side of the composite member, wherein the composite member has at least one low-grade wood portion forming at least most of the stepped-up inner surface, and
- a first strengthening sheet adhered to the stepped-up inner surface of the composite member.
A rail or stile for a window or door comprising
- an elongate composite member having front and back faces, and end portions, one of the end portions including a groove for receiving an edge of a glass sheet or panel, the composite member including at least one internal portion made of low-grade wood material defining at least parts of the front and back faces of the member, and
- first and second strengthening sheets substantially covering the front and back faces of the composite member.
