Do Thermal Curtains Really Work?


Thermal curtains are either double- or triple-layered heavy fabric with a thick backing of insulating material and often a polyester-film vapor barrier. Thermal curtains generally coated on the window side with acrylic foam or a layer of aluminum to protect it from ultraviolet damage. So, theoretically, they should block the heat radiations  😎

Interesting topic. I've always wondered the how-to's of these thermal curtains too. I get the idea behind blackout curtains and we have these in each bedroom of our home. I didn't know really how well thermal curtains work. Has anyone really seen a difference in their electric bill by using them?
