Review on ECLIPSE Bradley Stone Blue Thermal Insulated Single Panel Rod Pocket Darkening Curtains for Living Room, 50 in x 95 in by Brian Campbell

These curtains effectively block light. If you can fit it to perfectly match your windows (ie there is no gap at the top or bottom) you can achieve total darkness even in broad daylight. However, make sure they are absolutely flush as the back of the curtain is white otherwise there will be reflections. (If the back was black there would be fewer reflections, but the curtains would also get very hot in the sun!) Note that they don't block sound much. If anyone is interested in buying curtains that block noise let me know, I have a jumper or two for sale (ie no fabric curtains will ever block noise; anyone trying to sell you that crank marketing gimmick! You help in sound reflection (e.g. large empty rooms sound like "echoes"), but does not block outside noise.
