This helped to keep our bedroom a manageable temperature and in the summer that's hard to do in a tri-level. Took me a minute to figure out how in install it because I don't have your typical fabric curtains, I have a burlap type material curtains... but it went smoothly after I figured out the best way to do it.

Pros: Completely room darkening, controls summer sun
Cons: Shower curtain type look/feel
