Any company can claim their products are top quality, but the Vinyl Siding Institute (VSI) sponsors independent, unbiased certifications of vinyl siding performance.  Preservation Premium Siding has been certified under a VSI program to meet or exceed the rigorous battery of tests known as ASTM D3679 - the long-standing, accepted industry standard for quality vinyl siding.

Thanks to the certification program's third-party testing and inspection process, you are assured that Preservation Siding, when installed according to our instructions, will meet or exceed the industry standard for quality and performance.  In addition, you are assured that Preservation Siding will maintain a uniform color over time, lay straight on a flat wall, and withstand the effect of normal seasonal temperature fluctuations.
