Garn jr insulating

[waynewagner33]

I just put down payment on garn which I would like to thank the knowledgeable people on here for helping me make this decision. Now I have to figure out how to insulate it I would like to make a Sheetrock box for it with access for neccesarry openings my question is that what do I use to insulate the unit I'm thinking r 38 rated batts but I'm looking for suggestions and what has worked best for people the unit will be in my garage I'm converting strictly into a boiler room but would still like it to look professional

Search around here a bit but yea R-30....,38 is the way I have seen most people go....pay special attention to the Top, that is the biggest source of heat loss. Rock in the front with cutouts for all required access points is correct....it should basically look like a wall with a few penetrations through it....if I where going to do the Garn I would also consider ICYNENE as an insulation...Please start a thread with photos when you start the install....

I got mine up & running 3 months ago Wayne with R30 batts covering it. When warmer weather gets here, my plan is a spray job of closed cell foam on it. I've never done it [foam] before, so not sure right now if it gets hired out or I buy one of those kits. A future thread to follow.............

I would do it myself.....the guys I use to install residentially know how to do walls and ceilings......with the Garn you need to build a box, drill holes from the bottom up, fill and cap the holes as you go working your way up as expansion begins...you want to take your time and not have a guy with a truck and hose breathing down your neck wanting to get done...

Years back there was somebody was going to do a kit, like you might have used for Hot Water tanks back in the day. Seemed a good idea.

6 " Rock Wool and then used a lot of scraps I had to fill the gaps.

I used MgO board for the front, drywall seemed a bit 'soft'. Cement Board would work as well. You also do not then need all the bracing they have in the instillation booklet.

Not mentioned but to get to the back if you do not have access then i put in a walkway on top, also allows easy access to the manholes.
