Composite blinds are a fairly recent entry into the market. The slats come in flat or elliptical shapes. The slat surface is generally poly-coated. The choice of colors is limited. Composite blinds are priced in the low- to mid-range. They are quite sturdy, and UV and water-resistant. They are less likely to rot and easier to clean. Composite blinds are lighter than PVC blinds, but heavier than the wood variety. Value and premium wood blinds are made from Oriental hardwoods. The slats of premium wood blinds are made of American hardwoods such as basswood. Wood blinds are the most exclusive blinds a buyer can go in for. Wood blind slats are the lightest of all blinds and are the best bet for large windows. More on levelor blinds.
