We just recently had our lanai enclosed with acrylic sliding panels and are very pleased. Custom Windows did ours and we use the lanai as a den. My size was 11 X 15 and the price was just over $3600. The company came out and took the measurements and came back about three weeks later with the panels. Installation took about 1/2 day. Prices vary with exactly what you want. Mine are full length panels that slide in channels so that when opened, you could have four panels sliding behind each other to allow lots of air. They do have a spacer band about 24in. up from the bottom for stability. It looks good and is very stable and rigid.
We are very happy and consider this one of our best changes to our home.
Merry Christmas to all!!
