Am I doing this right?

[unknown_element]

Plan is bookshelf girts, pressure treated bottom board, r19 non faced bats, visqueen over that, then either steel or drywall. Should I put plastic under the pressure treated board? Tips or advice is welcomed, this is my first time doing this and want it to be right the first time. Garage is in northwest ohio, radiant heat in the floor, will be worked in daily.

well you got a good start ! believe me or not .....those vertical seems will allow air to blow in and kill your R-value. Since they are up I would foam them.

I think your talking about the seams in the steel skin? don't you steel building guys need a little air flow between the skin and the insulation to keep condensation from getting the insulation wet?
or could he have put plastic between the steel and wood before the wood went in?

The spray foam I have in there isnt enough? What else can I do? Its been that way for 2 years, I dont feel a draft coming thru with all the doors shut.

I used tyvek on my 40 x 60 and my boiler runs twice a day for 1-2 hours each time and 55 deg will stay most of the day if the power goes off. my buddy didn't use any o/s wrap and after feeling drafts in the winter ,we tore some of the i/s off and packed more insulation in to stop the drafts. btw, his electric boiler costs him about $400.00/month to operate.

Should I have put foam boards in between the girts? How can improve on my current setup?

i think its too late for board. I wish I would have had a contractor spray foam my walls . I have a million hours in trying to do it my self and still spent about the same money (about 19 yrs ago) They can spray the seams or skim coat everything.

As far as insulation goes, how thick? 5 1/2? I have 6x6 poles. Ok if the insulation touches the steel or do I go 3 1/2 thick?

5 1/2" just make sure its tight ,no air gaps and pack the corners !

At the top, I think its called the header, theres 2 2x12's , do I just stuff insulation in between them?

So between the girts should i have put foam in? Am i ok to put 5 1/2 thick insualtion in? It would touch the girt and have 1 1/2 air space to the steel outside. Unfaced rolls of insulation then 6mil vapor barrier? Thanks in advance i just want to do it right, smart and have no issues in years to come.

Why not just get a contractor to spray foam the whole thing?

Dont want to spend that much, had a quote of 3500.

2" of foam was better than r13 pink and it wasn't a whole lot more. I think the pink bats for the 1200 sq ft I had to do was over $1500 and the foam was $2200. I would have had to pay to put in the pink and put in the studs to hold it. I would have been over 2200 and the foam is far superior insulator and sealer.

I would wonder how much foam they are giving you and if it is too much.
