In case being super-low maintenance and the most popular cladding material in the country weren't big enough sales tools, the Vinyl Siding Institute in Washington, D.C. has introduced a new color retention certification program for vinyl siding and related products, i.e. trim stock, J-channel, soffit vents, and so on. Products certified through testing will be awarded the new VSI logo for color retention. After all, who wants to install a product that will stay on the wall but will end up looking gnarly a few years down the road, creating a backlog of callbacks?
