CenterLock® Energy Choice is engineered to provide superior energy efficiency. It has four times the R-value of conventional siding so it can cut your heating and cooling costs by as much as 20%. And, because CenterLock Energy Choice is manufactured with Fullback®, a precisely contoured insulating foam underlayment, your siding will have five times the impact resistance of conventional siding, standing up to damage from extreme weather and around-the-house accidents.

CenterLock Energy Choice also provides all the benefits of the patented features proprietary to the CenterLock panel. A mid-panel lock portrays the look of individual "boards" while the rolled nail hem provides superior wall holding power. Premium materials and a patented design make CenterLock Energy Choice one of the most attractive and dependable siding systems on the market today.
