For many years, vinyl siding manufacturers have provided consumers with top-quality, durable, attractive, and affordable products. As more and more homeowners across the country discover the benefits of vinyl siding, demand continues to increase.
The Vinyl Siding Institute (VSI) has developed a Certification Program to assure consumers - from homeowners and remodelers to architects and contractors - of the quality of the vinyl siding they select and use.
The VSI Vinyl Siding Certification Program ensures consumers that, by selecting certified vinyl siding, they can expect a product that meets a long-standing industry standard for quality.
