Do thermal curtains really save energy?

It helps save in the winter and the summer. they are worth the money. that is a really good deal on them. I would get as many as you can, those are not cheap.

Check with your electric or gas company. They may have a credit for insulation that might be applicable.

@steve: Since it’s a rental, that wouldn’t apply to this situation. Any curtains with a tight weave/thicker cloth will help…they don’t need to be thermal, though that’s probably the best. Check out JCPenney.com . They often have great sales on window treatments, and do sell thermal ones.

With the thermal curtains, you might not actually save enough money to pay for the curtains/blinds during your stay, but you should notice improved comfort inside during very cold weather.
