Blinds are ordinarily used for blocking out some light from rooms. In some situations, people prefer blinds that only partially block light, letting in a warm glow or small amounts of sunlight. However, others need blinds that block out most or all light for specific areas, such as nurseries or bedrooms, that they prefer to keep dark.
Cellular shades are a type of shade system that create cells of fabric, often in a honeycomb pattern when viewed from the side, according to Cellular Shades Help, a website dedicated to the product. This structure allows the shades to be collapsed easily into a small space. Cellular shades are versatile: There are versions that owners can collapse either up or down to let light in the top or the bottom of the window. When closed, however, the layers of fabric provide very good light blocking, and blackout versions are available, according to Cellular Shades Help.
Blackout blinds are made of materials designed to block out light. These shades are used in rooms that need to be completely absent of sunlight, and using synthetic films and thick materials that do not allow any light through, according to The Daily Green, a website devoted to "the green revolution." These blinds are used by those who want to simulate nighttime during the day (such as graveyard shift workers).
Indoor shutters are made of either wood or plastic, like vinyl. They are built in a quaint, cottage style and offer variety in terms of appearance and price for homeowners. Since these shutters are built of solid materials, they block incoming light very well when closed, according to the Shutters Direct website.
According to the Best Blinds website, roller shades are drawn up and down from a roller mechanism suspended above the window. Rollers are good at holding heavier materials, making them ideal for blocking out light. Rollers can also be used with plastic shades or felt liners that are added solely to stop any sunlight from entering rooms.
