Improved weather- or insect-proofing cover

Abstract From the Canadian patent

A frame construct for holding at least one planar mesh or membrane in set-apart relationship from a structural port(al). Individual frame pieces top, bottom and sides, are cut to desired lengths and joined to form a glazable frame. Shapes other than of rectangular geometry are obtainable through use of variously angled joiners. Peripheral grooving on both frame faces is receptive of a spline that secures the planar mesh or membrane to the frame. which is then dogged to or otherwise secured in place on/over an opening such as a window, door or the like. Corner elements of the construct also serve as joiners; and, one spline may also comprise a weather strip.
