Today's a good example:

Attic 117.6 degrees
Garage 88.3
Outside 93


Knocking on the door of 30 degrees cooler.

:evil6:

Yeah, 20 degrees seems pretty easy. I’m at 30 without any extra insulation.

In my case, at 3 PM, outside air temp is 99, garage temp is 95. No ceiling insulation. I don't care what the attic temp is, or the garage temp either. I don't live in the garage or the attic.

That’s great.

72 degrees here
 

My garage attic and garage stay 72 to 74 degrees all day. Costs about 10k to get it like mine and for us well worth the expense, because of the needed attic storage space....so maybe not worth it for villa attics??? I can't say because I've never been in a villa attic. I can say that the cool garage buffer space keeps the whole house cooler and my main ac will work less. Our house faces west and after noon the garage doors will fry your hand and or a ribeye. Before enacting my upgrades our garage was easily 120 degrees in the afternoon. Cool garages are achievable and less than what my Boss spent on custom closets:crap2:

swmbo. 😃

Yes
 

She has an attic full of Christmas she could not part with.... yet.....sequela is I get a climate controlled garage to play in lol. I take full credit for designing and implementing the climate control. I put my foot down at majic stairs and elevator....told her to go back to work and buy a premier home with a 4 car garage and that ended the conversation. She happily got up in the attic as I pushed all the boxes up the ladder....since it was only 72 degrees up there

Way to put your for down!

I'm thinking about insulating and installing a mini split. I love to tinker but it's pretty warm out there. I just insulated and installed a mini split up north and it was about 2500 bucks all in. I asked someone for an estimate to blow in insulation in this garage (3 car with 2 for extension) and they wanted 1500). Ouch.

The key to it all is 10k and thinking outside the box and spray foaming in the trusses, the front, and making a wall to enclose the attic....just like a cooler. I now control the environment....I'm acting like a liberal Democrat lol:sing: Ceiling insulation, that everyone buys, is a waste of money when it comes to an unconditioned space. You've added insulation to a hot space that stays hot and your garage doesn't change Temps much afterwards. I love to tinker but chose not to install a split myself because I may sell my house and want all the proper permitting, a Mitsubishi, and a company to back up their work. I'm insulating my garage doors myself because my research said my plan would be best for me and my west facing doors. Conklin Construction did my spray foam and attic ladder. Kalos did my Mitsubishi. More than pleased with results

If you want insulation blown in the attic, call the Solar Guys. They run specials periodically and you can use the cost of the project as a credit on your income tax. Their prices are reasonable.

What no one is talking about is insulating the garage ceiling will prevent it from superheating and cracking. If you don't insulate, the ceiling will crack no matter what you do. Same for the Lanai ceiling.

Whether to insulate or not depends on your garage's exposure. If you have a West or Westerly exposure in the afternoon, you want to insulate your garage and the attic above it. You will have a cooler garage when the door is down and your ceiling won't crack. That's it.

As far ar replacing your garage attic ladder. Did you know that you are supposed to install a fire rated ladder? Your garage has a 20 minute fire rating meaning all the sheetrock is 1/2 inch to prevent fire from spreading to the rest of your house for 20 minutes. The building code does not address attic ladders specifically but does say if you make a penetration, like installing a ladder access way, you need to fill the penetration with 20 minute fire rated material such as 1/2 sheetrock. In the case of installing an attic ladder you need to install a fire rated attic ladder to be code compliant. You can get these at Home Depot but they are special order and no one that I know of except myself has ever installed one or even knows about this requirement.

Does your "solar guys blown in insulation " and "special order ladder" slow the "super heating" of the garage ceiling thusly slowing it's cracking and before bursting into flames, so you can test out your ladder's fire rating just before the structure collapses? Is the "super heating" caused by an evil maxi mirror designed to relect heat into the drywall? Asking for a friend because nobody is sure how fire became the topic. We will need Fire Marshall Bill to tell us about fire....but my garage is 72 degrees

Everything thing you can do helps. Attic fan, attic barrier [ saved 15% on electric too], Insulate garage door, new windows.

You are correct, fire rated sheetrock is 5/8". The building code here states 1/2" gives you a 20 minute rating and that's only used if there is no living space above the area in discussion. For us here in the Villages, usually the attic space above the garage is open to the rest of the attic over the living area. If a fire breaks out in the garage, when it penetrates the ceiling it quickly spreads to the rest of the home. But as you mentioned, this is not the topic of this thread.
