When replacing your windows, there are several options. Vinyl replacement windows are very common and made using components made of polyvinyl chloride or PVC. Polyvinyl chloride is a combination of different chemicals, plasticizers and pigments. It is also used to make plumbing pipes, electrical pipes and many other plastic items. Window components for vinyl replacement windows are extruded and contain hollow chambers which make it a lighter product and easier for welding. The second type of window is also made from polyvinyl chloride; however, through a different type of manufacturing process where the components are solid known as Cellular PVC. It features a foam or cell structure inside which can be nailed, sawn, and fabricated like wood. The window components such as brick mould, sill, jamb and sash rails used to manufacture these windows look exactly like wood windows. Cellular PVC windows are solid and stronger than extruded vinyl windows which are thinner and can lead to warping.
