1. Field of the Invention
This invention relates generally to window construction and especially to a window assembly wherein the window has a non-wooden frame assembly. In particular, this invention is directed to non-wooden double hung windows which open and close by vertical movement of the sash.
2. Description of Prior Art
Homeowners or building owners of old or historic properties are faced each summer with the tedious and time-consuming challenge of removing numerous old wood-framed storm windows and replacing each with wood-framed screens to allow airflow. This task is made even worse by the possibility of dropping and breaking the windows. At the end of summer, they must replace the screens with the wood-framed storm windows.
A common issue with renovating windows in older homes or buildings is the desire to preserve the historic, wood appearance of the windows as viewed from the exterior of the house. Namely, the wood-framed storm or screen is flush mounted with the window casing and painted the same color. Many city councils or agencies even require that owners of historic homes or buildings preserve the original appearance of these houses. Owners are therefore confronted with a dilemma: their desire to improve the functionality of the wood-framed window with a modern, energy efficient, low maintenance design, but a need to retain the overall appearance of an all-wood storm window or screen. Modern non-wooden double hung combination storm windows typically consist of an aluminum or vinyl frame. While offering many advantages over all-wood windows in terms of maintenance and insertable screens, modern metal or vinyl windows do not offer the pleasing aesthetics of the historic all-wood windows. Furthermore, it is impractical and costly to paint the metal or vinyl windows to match exterior casings or trim.
Additionally, a common problem exists for the wood frame and non-wood window combination: moisture collecting in the bottom of the window frame.
The U.S. General Services Administration Historic Preservation Technical Procedure, U.S. Pat. Nos. 4,558,536, 4,837,977, and 5,081,793 are of general interest, all of which are incorporated herein by reference in their entireties.
Despite the teachings of the known prior art, there exists a need for preserving the historic appearance of older home and building, while introducing the conveniences of modern window design. What is needed is a combination replacement storm window, which retains the wood appearance of the original wood frame, but combines with it a modern, low maintenance non-wooden double hung window containing moveable sashes and screens from the interior, for easy cleaning, for example.
While this invention may be embodied in many different forms, there are described in detail herein specific preferred embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.
In an embodiment of the present invention, a non-wooden double hung window is inserted into a wood frame, including horizontal and vertical members, and a center member, such that the vertical and horizontal members of the non-wooden double hung window along with the non-wooden elements of the upper and lower sash are substantially hidden when viewed from the exterior of the building, thus preserving the original, wood window appearance. The window is fastened to the wood frame and then attached to the building, or existing exterior window or screen hooks can be used. The non-wooden double hung window may be constructed from metal, vinyl, or any of a variety of other non-wooden substances, and includes a screen.
The step of fastening the non-wooden double hung window into the wood frame may include caulk and glue, along with screws or any other method of securing the non-wooden double hung window to the wood frame, including existing exterior hooks.
Another feature of the present invention is the drilling of at least two weep holes in the bottom of the wood frame to allow moisture drainage. This prevents damage to the wood frame caused by draining away moisture that may seep between the wood frame and non-wooden double hung window. The weep holes can be drilled at angle so as to allow drainage from the bottom horizontal member of the wood frame attached to the bottom horizontal member of the non-wooden double hung window to the exterior of the wood frame. Additionally the weep holes can be lined with a water resistant substance, preferably plastic, to prevent the wood interior of the weep holes from contacting the moisture.
The present invention also includes routing at least one groove in the center bar of the wood frame. A non-wood stiffener, preferably aluminum, with at least one protrusion matched to the at least one groove in the center bar may be secured to the center bar to stabilize the frame.
Additionally, the present invention includes routing at least one groove in the bottom horizontal member of the wood frame. A non-wood, preferably aluminum, weatherguard strip with at least one protrusion matched to the at least one groove in the bottom horizontal member may be secured to the bottom horizontal member.
Also, the non-wooden double hung window of the present invention includes a screen in the upper portion, lower portion, or both. Furthermore, another embodiment of the present invention would incorporate a single, full-size screen that covers both the upper and lower portions of the non-wooden double hung window.
