NAPCO: Siding with the Builders of the American Dream
For generations NAPCO has stood side by side with homebuilders, distributors, investors and families interested in improving the appearance and value of their homes with beautiful, durable, low-maintenance vinyl siding. It all began in 1963, when three companies joined together to become National Aluminum Products Company (NAPCO). Since then, we have become an industry leader, manufacturing the finest quality vinyl and metal exterior products available today. Every piece of the NAPCO product line has been carefully researched, thoroughly tested and precision crafted to provide a lifetime of beauty and protection. And we offer a complete selection of products that appeals to every taste — and budget.
Today, as a part of the Ply Gem Siding Group, NAPCO continues to pursue quality and value through its wide range of high-quality, affordable home exterior products.
State-of the art technology is at the heart of every product that bears the NAPCO name. We’ve created and patented panel locking technologies that ensure a tight fit and maximize panel rigidity. We developed a unique, color-through, scratch resistant technology that means our vinyl panels stand up well season after season. And our Signature Series deep color palette, available in our American Herald® siding line, is protected from excessive fading by proprietary polymer technologies that offer extra UV and sun protection, which results in superior color retention.
