I recommend using door draft stoppers in South Florida.
They keep in the cold air.
When the wind blows it does not suck out all of your high priced cold air.
The little gadgets are also handy at keeping out bugs and spiders and snakes.
of course, they are also excellent at keeping in the warm air if you live up north. these door draft stoppers also work with windows and are good for lowering both your heating bill and your air conditioning and electric bill.
I have a link to the one I bought and use in my Amazon store.
If you buy anything from my store, or if you save my Amazon link and use it
to go to Amazon in the future then Amazon will throw me a few cents if you buy anything at no cost to you.
