One of the most recognized benefits of vinyl doors are their insulating properties. Vinyl windows are made from a plastic called polyvinyl chloride, also known as PVC. PVC has a high R-value, which is a numerical value assigned to the amount of insulation a material has. When compared with aluminum, vinyl keeps your heat from escaping during the winter but protects your home from heat entering during the summer.
Combine vinyl windows with double or triple pane glass that is glazed with Low-E and filled with Argon gas for even more insulation. The Low-E prevents harmful UV rays from entering your home and non-toxic argon gas is pumped between the panes to act as another cushion of insulation.
