I found this link:

Screen Tight

This company has a product called Screen Tight that I installed last Fall on my patio for winter protection. I used the Screen Tight to fasten clear greenhouse plastic inside of the screens. I have truly enjoyed the patio being protected. It has proven to be an excellent alternative to installing real windows, and it looks nice to boot....

This type of system has worked out so well for me that I decided to leave it up all year around. It has had the added benefit of preventing some of the excessive amount of heavy rains during high winds from soaking the floors and everything else in the patio.

I think you will find the site quite interesting, and for those of you who reside near Columbus, OH, you may want to give them a visit...

Enjoy!
