The centerpiece of the Generations® Energy-Efficient Exteriors System is Generations Thermal Core Siding, a line of thick, premium foam backed vinyl siding designed to look great, provide value, and protect your home for a lifetime.

Generations Thermal Core Siding has a thick polystyrene foam core that will provide a lifetime of benefits far beyond normal exterior cladding. The permanently applied foam backing helps insulate your home, keeping it cooler in summer and warmer in winter.

The insulating foam core of Generations Thermal Core Siding increases rigidity for straighter, smoother lines, and has significantly more impact resistance than hollow backed vinyl or metal sidings: up to 4 times more resistance, which improves the performance of your exterior against hail storms, thrown baseballs or moving lawn mowers.

Because Generations Thermal Core Siding exterior is solid vinyl, it will never crack, blister, flake or peel, so you never have to scrape, sand or paint ever again.
