What is vinyl siding?
Vinyl siding was introduced in the 1950’s as an alternative to aluminum siding. It is currently, by far, the most popular type of siding in the USA. There are two layers called cap stock and substrate. They primarily consist of polyvinyl chloride and resin. The top layer uses titanium dioxide to protect coloration and from UV light damage. The second layer contains limestone to facilitate manufacturing and decrease costs. Vinyl siding is available in a variety of colors and can simulate architecture details that were once made of other siding materials.
