Just happened across this old post about property taxes, room enclosures, and glass vs acrylic.

We enclosed our lanai at the same time we added a large bird cage. Shortly after the work was done we got a visit from the Sumter County property appraiser's office. The individual was very specific, there were two permits issued, one for the "Screen Cage" and one for the "Type III Sunroom". He stated that our property taxes would go up because of the addition of a Screen Cage, but not for enclosing our lanai and making it a Type III Sunroom.

Our enclosure is with double pane insulated glass. The key, as explained by Chris Fox of Cook Aluminum, is doing a "Type III Sunroom". (I'm sure Chris could explain it better than me, his number is 352-693-6079.)

I think glass is the way to go. Looks good, doesn't scratch like acrylic, no stickers advising removal in high winds, and much better at maintaining temperatures.
