People often ask about the difference between vinyl types. Here’s a shortcut: it’s like baking. The three types of PVC (monomeric, polymeric, and cast ) have similar ingredients—the difference is in the manufacturing process. Cast PVC is the highest-quality type, and it’s the kind we generally use. It is poured into a casting tray, similar to a cake tin. Monomeric and polymeric PVC types are less expensive because the PVC is “calendered,” or flattened, similar to a pizza crust. Chemicals are then added to keep the PVC from shrinking. By and large, monomeric and polymeric PVC products last between three and seven years. Cast vinyl, however, lasts closer to a decade. That’s why we prefer it for any long-term installation.
