Choose independently certified products and installers

Vinyl siding, including insulated vinyl siding, is the only exterior cladding with a product certification program administered by an independent, accredited quality control agency that ensures products and colors meet or exceed the national consensus standards for the product category and a certified installer program with validation by an independent, third-party administrator to ensure that installers demonstrate knowledge of industry-accepted application techniques.

VSI Product Certification Program
More than 98 percent of vinyl siding manufactured in the United States each year – covering more than 750 products and more than 400 colors – is certified through the VSI Product Certification Program. Through twice-yearly, unannounced inspections of certified productmanufacturers and rigorous testing, the quality control agency ensures that certified products:

  • Withstand the impacts of recommended installation procedures
  • Lie straight on a flat wall and does not buckle under normal conditions
  • Weather the effects of sunshine, rain and heavy winds of 110 mph, and most achieve a wind rating higher than that
  • Meet manufacturers’ advertised specifications for length, width, thickness and gloss
  • Are available in a wide variety of attractive colors, with an independent process to certify colors for color retention.
