ABSTRACT:
A trim assembly comprising an integral trim member having a generally L-shaped cross-section, in which one leg of the L is adapted for attachment to a wall to serve as the casement, while the other leg (flange section) projecting towards the window is adapted for attachment to the jamb surface of the window opening. The interior surface of the flange section is provided with closely-spaced, longitudinal grooves extending the length of the trim member. These grooves, preferably spaced at a distance of about 1/8 to 1/2 inch, are easily cut or broken off whereby the width can readily be modified to properly fit a wide variety of jamb-widths. The instant trim member, featuring a flange projecting towards the window, permits for the design of a hollow enclosure which can serve as a housing for a small blower to provide a source of flowing, preferably heated, air. The blower will preferably be incorporated within the sill-trim member, having ducts connected to similar ducts in the side-trim members and/or in the head-trim member, in turn communicating with inclined outlet apertures. Thus, air from the blower motor may be conducted through the ducts and exit the apertures so as to flow over the window surface, preferably as a sheet of air, thereby preventing condensation on the windows and the resulting moisture damage to surfaces in proximity therewith. In an alternate embodiment, the blower rather than being housed within a trim member, may be housed directly within the window frame, similarly to provide a source of moving air over the surface of the window.
