A window sash is formed from a pair of one-piece injection molded sash body members having substantially the same mechanical configuration. Each sash body member has an inner, facing surface and a non-facing surface. The facing surface of each sash body member is provided with a plurality of locators of two different types, arranged about axis of anti-symmetry. The two different types of locators are complementary to one another, and so are configured to engage each other. This allows a window sash to be formed of substantially identical components that are mated together. Each sash member may be provided, on its facing surface, with a weld wall that is set back from the outer sash member edges. The window sash may be assembled after heating the weld walls and joining the two substantially identical sash members.
