Abstract:
The present invention provides (1) a sash window assemblage having basic wood construction with selectively milled kerfs and (2) exterior vinyl cladding in the form of vinyl extrusions of particular configuration. These vinyl extrusions, in cross section, feature facing portions that lie snugly against front and edge surfaces of the rails and stiles of a window sash, gripping portions that snap and lock into the kerfs, sealing portions that squeeze tightly against the rigid elements they contact, and spline portions that extend upwardly and downwardly. The spline portions can be cut readily for conformation with an out-of-plumb frame. The facing and gripping portions have sufficiently great cross sectional thickness to impart rigidity. At least sections of the sealing portions have appropriate composition and sufficiently small cross sectional thickness to impart flexibility.
