There are so many reasons why vinyl (PVC) makes for superior doors and windows, not the least of which are environmental. From beginning to end, PVC has one of the smallest carbon footprints of all comparable building materials. Vinyl is one of the world’s most versatile plastics and is used to make everything from medical devices to flooring.
Vinyl is widely used for building and construction because it is strong, resistant to moisture and abrasion, will not rot or corrode, does not require painting and can be cleaned with mild cleaning products. It is ideally suited for windows/doors, pipes, cladding, fencing, decking, roofing, wallcoverings and flooring. There is little waste: “Virtually all of the vinyl is converted into product,” says Dr Patrick Moore. “The scrap, trim and off-spec material is recycled from the vinyl production process. This adds up to more than 1 billion pounds per year. This means that 99% of all manufactured vinyl is made into products – not sent to landfills.”
Vinyl is largely derived from salt via chlorine, an abundant and inexpensive resource. While some, such as Greenpeace, denounce chlorine, Dr. Moore, a founder of the group who later left in part due to his science-based understanding of the benefits of chlorine says, “Chlorine is the most important element in the periodic table for public health and medicine. It purifies our drinking water and contributes to many of our prescription medicines, thereby preventing the spread of disease.”
