Review on 2-Panel Thermal Insulated Blackout Curtain Liner Set - 50X58In, Off White Panel + Rings Included by Bryan Moon

The liners work very well to darken a room and seem to provide some insulation from heat and cold. The rings are a bit hard to open, but are sturdy. I have tab-top curtains and slid the rings between tabs and it works fine. They do not seem to help block noise at all--maybe they are more effective against certain types of noise, but I live within 1000 feet of a casino and the huge generators to heat and cool the place run 24/7 365 days a year and the liners did not help reduce that noise. Overall, the liners provide some benefits and should prevent my drapes from fading from the sun so I ordered another pair for a different window.
