The 1.5 inches of insulation in each 16-foot 8-inch Prodigy siding panel is form-fitted to the outer panel to prevent tearing and rattling even in the strongest winds, and Prodigy siding comes with a lifetime transferable warranty. CraneBoard 7 is a 7-inch clapboard plank style of insulated vinyl siding that reduces noise up to 45 percent, has 64 percent greater impact resistance than siding that is not insulated, and withstands winds up to 160 miles per hour. It comes with a life-of-the-home limited warranty. Norandex's Generations siding has a polystyrene form core that insulates and increases rigidity, providing straighter and smoother lines and more impact resistance. According to ASTM testing, Generations thermal core siding can withstand winds in excess of 180 miles per hour.
In similar testing, Richmond Ultra withstood winds up to 250 miles per hour. Richmond Ultra features a self-aligning locking system that allows the vinyl and foam to function independently as temperatures change. Integra siding features 1.5 inches of insulation with longer siding panels, 16 feet 8 inches, than standard siding options and a patent-pending stack-lock system that ensures a tight, straight fit.Learn more about Building Materials
