I searched all over town looking for roller shades, at a reasonable price, for our houseboat to place my own fabric on, but these are perfect solar shades. We placed them side by side, so we can open half while keeping the other half closed on the sliding windows. The color and quality is way above anything I would have expected for the price, I couldn't even by the cheap plastic ones at the local big box store for this price. Try them, you will not be disappointed.
