Convenience and durable performance in a traditionally styled package. That’s what you can expect from the New Next Dimension double hung windows. Our double hung windows feature an integral lift/pull handle and tilting top and bottom sashes that make cleaning a breeze. Constant force balances provide smooth, effortless operation.
With convenience comes years of strength and energy efficiency. New Next Dimension products utilize a fusion welding process in the frame and sash corners to increase strength and leak-resistance. Additional energy saving and weatherproofing features include the Windsor Glazing System, thick, multichambered vinyl extrusions and a unique interlock extension that provides full interlock contact and pile weather-strip compression from side jamb to side jamb.
