I would like to know the best and most cost efficient way to cool my 400 sq. ft garage in sunny Florida.

Could you explain to me in laymens terms the best and most cost efficient way to:

1) insulate concrete block walls

2) insulate the ceiling

3) insulate the garage door (or buy an insulated garage door) *** I would still like to still open and close the garage door

4) best cooling system to use in a garage with no windows and no other outside doors (portable unit vs wall unit vs hooking into central air)

5) I am also wondering about sound proofing...will this insulation you recommend provide enough sound proofing for an aspiring rock band or is there an additional thing you would recommend?

6) any other thing you would recommend, that I might have overlooked, to totally cool and sound proof my garage

I had this very same question a couple of yrs ago.

I bought one of then room coolers, with the vent hose that goes outside - worked alot on the design (the garage door would almost close - built a thing along the garage floor about 1 foot high, the vent went to the side

Forget that idea - even the most btu's for one of them units cant cool down a garage that gets hot - only the work area, very annoying

What does work is the styrofoam sheets you can get and HD or Lowes - about 3" thick, comes in sheets 2x4 if i remember right - not much work to get them all to fit into the panels of your garage door.

As far as the ceilings - I dont know, but since you want to insulate against heat and sound - I know for a fact mattresses work great, have to be creative at how you install em to not look cheesy, but have been in many practice rooms that are very good at keeping the sound in - with just a bunch of mattresses

I dont understand how it is so hard to keep cool, we are surrounded with blazing cold, its so dang easy to make warmth - why is it so hard to take it away?
