Vinyl siding

Vinyl siding is plastic exterior siding for houses and small apartment buildings, used for decoration and weatherproofing, imitating wood clapboard, batten board and batten or shakes, and used instead of other materials such as aluminum or fiber cement siding. It is an engineered product, manufactured primarily from polyvinyl chloride (PVC) resin. In the UK and New Zealand a similar material is known as uPVC weatherboarding.

Approximately 80 percent of its weight is PVC resin, with the remaining 20 percent being ingredients that impart color, opacity, gloss, impact resistance, flexibility, and durability.^[1] It is the most commonly installed exterior cladding for residential construction in the United States and Canada.^[2]
