A: Certain kinds of roller shades, cellular blinds, and roman shades are specifically designed to eliminate daylight. Room darkening cellular shades might be perfect because, in addition to blocking the sun, they provide insulation against both heat and noise.
If your looking for something a little simpler, however, you may want to look into vinyl roller shades. These low profile shades are easy to install and even easier to use.
Roman shades have also been popular as room-darkening shades. They're available in a wide range of fabrics so you have the option of choosing a darker or heavier fabric to block light. They also come with optional liners to help eliminate unwanted light and their soft folds are perfect for creating a warm ambiance in any bedroom.
