Vinyl siding, made of polyvinyl chloride (PVC) resin, originally debuted on the market in the late 1950s as a replacement for aluminium and fibre cement siding.

Vinyl siding is a type of plastic exterior siding that is commonly used on homes and small apartment buildings. It maintains a consistent visual appeal providing weatherproofing and fire resistance. The majority of vinyl siding is made to imitate wooden clapboard and is available in a variety of colours.
