A rubber-like solid that will not crack or fall out of joints, NovaFlex Void and Cavity Filler is the best way to reinforce your frame.

NovaFlex Void and Cavity Filler is a non-sagging, non-corrosive, single-component silicone paste that cures upon exposure to atmospheric moisture and remains flexible forever. It is ideal for use as a reinforcing sealant during the window manufacturing process, or to fill voids, gaps, and cavities inside the assembled window frame. It may also be used as a vertical joint sealant and crack filler.
