Our classic room darkening roller shades are a simple, effective, and affordable window covering choice. They feature a standard spring roller lift mechanism and a straight bottom hem. An optional continuous loop lift chain is available at no extra charge. They block 100% of natural light which makes them ideal for both residential and commercial applications. Made with a rugged 12 oz. 4-ply construction (3-ply vinyl and 1-ply fiberglass) our roller shades meet the State of California's strict fire code for flame retardants. These shades come with a white backing, so no matter how many colors you choose, you'll have a uniform appearance on the streetside. Their slight luster makes them easy to clean and washable with mild detergent.
I was just curious of this "Room Darkening", so I checked on Youtube for god knows what reason, and here it is! Strange.
