I bought 3 Walnut Color Exterior Shades 72"W X 86"L for my screened in Lanai.  I live in Central Florida and these shades do an excellent job blocking the UV, making the Lanai so much cooler in the afternoon hours.  We have also received many compliments from our friends and neighbors on how good they look. This is an excellent product and I would recommend them to anyone who is looking for a very well made outdoor shade that is effective in blocking the UV from the sun.  It is also is a great privacy shade too.  You can raise and lower the shades using a crank handle which is very easy to do.  The bottom of the shade incorporates bungee tie-downs to prevent the shade from moving on a windy day.
