Son in law can.  The company he works for is doing it.  He'd need to know how thick and if you're using open cell or closed cell foam.  Closed cell is almost twice as expensive.

Closed cell has more benefits.....more R-value per inch of thickness, so sturdy it will help structure against wind, water resistant, but more costly.

All correct.  I'm going open cell though.  If you look strictly at R value per dollar open cell has a slight edge.  The other benefits of closed cell I really don't need.

 

Edit: I was just told that closed cell is about twice as expensive when comparing R value per dollar.

I think around here it's more than twice the price. Both work well.

… o O (since we're talking about the garage) consider a condensation drain pipe from the a/c unit - to a sump pump well, for a backyard sprinkler invention.... you still have time to put a conduit branch in there 🙂 … o O (no reason to sleep when a crew is scheduled for tomorrow)

 

edit explanation lol - well is a sunken 5 gallon bucket with a proximity sensor...  (a screen over the top to keep your dog from lickin' it dry) the submerged pump could be a low voltage pond unit... the sprinkler system could be 3/8" poly tubing mist system.... just an idea before the garage (the drive in yeti) is sprayed with open cell foam EVERYWHERE... during a dry January...

R value is only that. How much a given thickness insulates in a laboratory measurement. In the real world the effect of foam insulation is more complicated. Because it seals all the leaks in the building envelope if applied correctly. I've lived in a fiberglass bat insulated home and a now a foam insulated home. The difference is night and day. Of course you knew all this already.

That pic was out of order so I changed it up.

They're doing a great job of getting everything.  One guy is spraying and the other has started shaving the excess.
