Exterior window louvered shutters come with fixed or operable shutters, and they are available in a variety of materials such as wood, vinyl, composite, fiberglass and aluminum. Manufacturers make louvered shutters in heights ranging from 20 to 100 inches and in widths from 12 to 16 inches to fit a range of window sizes and architectural styles. Shutters may be ordered pre-painted in popular colors such as black, gray, blue, brown and green.
Wood is an attractive, traditional material for louvered shutters, but in harsh weather conditions it may warp or rot. Polymer composite shutters are long-lasting and durable when exposed to heat, cold, dryness and humidity. Vinyl shutters are a low-cost option that require little maintenance. Fiberglass shutters are highly resistant to warping and fading and are a good choice for extreme environments such as the desert or oceanfront. Aluminum shutters are strong and lightweight, and especially resistant to extremely cold temperatures..
Whether they are part of fixed or operable shutters, louvers should be 25 percent open and point downwards towards the house when open and downwards away from the house when closed. This angle sheds water away from the window and blocks the sun’s rays from entering the room when closed and presents aesthetically pleasing shadow lines when open.
