Window Sills ~
Grifform Innovations® Window Sill Systems are available in two styles. Our window sills feature a soft thermoform design and come in six radius front edge heights, 1½", 2", 2½", 3”, 3½" and 4". The depth are in
increments of 2” starting at 6” from the front wall face back to the window. Special depths are cut to
specifications. We produce 96” lengths using ¼” or ½” material. Our ¼” sills are prepared with subbase
material and structural foam factory mounted and ready for fitting. For installation Grifform Innovations® Window Sill Systems has a patent pending Installation Fixture which allows the installer to cut the
necessary wing return as required for either 1” radius drywall corners or square corners. The return is
then miter folded and glues to the wing.
