Lichtenberg and Co. Thermal Blackout Liner Panels, Drapes, & Curtains at Linens 'n Things

On August 23, 2011:
I bought a pair of these and put them behind my (not sheer but not see thru) drapes. While i notice my room is noticeably cooler there is still a LOT of residual light coming thru them. So i would give an A+ for the thermal since i can put my hand near them and feel no heat. But C- for the blackout part of them. perhaps if i purchased more panels and squished them together?? But at 50+$ a pair if i need two pairs to get them to work i might as well buy blackout drapes. I expected them to work as well as the blackout drapes i purchased for my living room. They do not.

This liner did nothing to block out the sun or the heat from my bedroom. It claims to block out 99% of the light, but even with this liner on the panel curtains I bought the sun still shines right through. This is a horrible product.

our sliding glass doors get direct afternoon sunlight which causes our den to get uncomfortably hot. no one goes near the den until after sunset. i bought these liners with the hope that they would block out some of the heat and to my surprise, they work great! i would not be surprised if my electricity bill is reduced this month! i can't believe how well they work, plus, you can't beat the price!
