Utilizing the latest manufacturing techniques, Gentek products represent a companywide effort to achieve only the uppermost industry criteria. And since the Gentek brand is distributed throughout North America, our materials and manufacturing processes must meet tougher requirements than those imposed for U.S.-only manufacturers.

In addition to our manufacturing system being so modern, it's also the most efficient. More than 99 of 100 Gentek vinyl siding orders are shipped from the company to distributors in 1.7 working days — outperforming the industry average.

Available through a widespread distribution network, Gentek products have been engineered to meet architectural specifications, make installation faster, decreasethe number of callbacks and provide the long-lasting beauty that homeowners desire most. We also offer dynamic marketing programs, such as the Pro Builder and Preferred Renovator networks. Not to mention effective sales support — including our innovative eVision™ Home Exterior Design Planner CD — and an extensive selection of Gentek-brand premium items like durable jackets, shirts and caps.
