Do you live in a place where winter is really white and cold? If you do, you probably know how much of your expensive indoor heat gets lost because of thermal exchanges that occur all over glass surface. Glass is indeed an awful thermal insulator, yet many of use love big windows, mostly if we have a house with a beautiful view. For such windows, insulated curtains are an affordable and effective solution for creating a radiant barrier that would prevent cold drafts formation inside the rooms.

Making your own thermal insulating curtains or drapes is very easy. It’s enough to double your regular curtains with an insulating lining layer. You sew the two pieces of fabric together, then hang your curtains back to the windows and add some Velcro tape on the backside of the curtains and on the walls, in order to make the three free edges of the curtain stay pressed against the wall.

This is one of the cheapest home insulation methods that can significantly improve the r-value of your windows, thus increasing your thermal comfort and decreasing your energy bills.
