Closing on a Villa in Bonita at end of this month. Looking forward to moving down from South Alabama. Will be getting new golf cart.
Wondering why many people insulate their garage doors. It seems that, since the garage is not heated or cooled, it would quickly assume the outside ambient air temperature.

You are correct. A waste of money.

Unless you plan to spend a lot of time in the garage.

Take your time and observe and ask questions. Some people get new shrubs and bushes and trees right away. Wait a while. Find out if you really WANT Palm Trees.

Don't buy anything from people who come knocking on your door. Talk to your neighbors and ask them questions.

The garage may get significantly warmer than ambient temperature due to radiant heat depending on direction garage is facing.

The need for insulation also depends on the direction the garage door faces, West in the summer can be brutal.

Don't do anything for a year. Be sure you will be staying in the villa. Lot of people moved multiple times.

Garages that face east heat up really quick. If your house faces east, talk to your neighbors, who's houses face east.

Most people do not insulate their garage doors.

After you move in, and when the sun has been on your garage door for several hours, stand in the garage and hold your hand about an inch away from the door. Since I do not have a surface thermometer, this is what I did, and it felt like an old hot water radiator. I insulated my 18 foot door as well as my cart door for under $100.00. Yes, it does help.

If your garage faces East, as mine does, then the sun will heat it up every morning. It will be hotter inside than outside, even if you have a screen door instead of a steel door. Does insulation work? It could if you used, say, four inches of foam, but even then I’m mot sure. How most of us heat our garages the most is driving a hot car into the garage. It’s like having a huge iron stove burning in your kitchen. I guess the ideal garage door here faces North, but that isn’t easy to arrange. Or buy a house with a car port on the Historic Side of The Villages.

If the garage is insulted, the door would be the weak link.

If your house is facing south ( or in the sun for a good part of the day) you may need it during the summer to keep it cooler. If it faces north you probably won't.

It is a waste if all you do is the garage door. You need to at least insulate the ceiling and better yet install a radiant barrier. The ceiling area can easily get over 150F.

a lot of people just use the flexible aluminum stuff,not much use...try the 1 in or 1.5 in see if you like it..if you are out there a lot ????
