| I just built a pole barn, it 24" by 40" with 10' walls and a 4/12 roof. I want to heat it with radiant floor heat. I'm trying to figure the best way to insulate it. My first choice is closed cell spray foam, but the budget will only allow 2". I want the structure to be as tight as possible and plan to use a HRV to control air quality. Am I on the right track or does anybody know a better way? The building is located in Central Maryland. Thanks, |

The building will be a metal/wood shop. It will be heated by a radiant system in the slab. Winter heating requirements would only be up to 60 deg F.

2" is probably OK for a shop, I question the neccesity for a HRV, an exhaust fan is probably better suited for fume and dust, your air infiltration will be around door and window openings, unless you provide another fresh air supply inlet near exhaust.
If you are already having trusses, purlins and girts like a traditional pole building you may want to consider 2"-3"steel SIPs that already have the roofing and siding integral with panels. saving a step and providing a clean washable interior surface

This building is kind of an experment. I'm trying to build the lowest cost ($25 to $30 per sqft), most energy effiecnt stucture I can. The goal is to get it as air tight as possible, that's why I chose the closed cell foam for insulation and air barrier and the HRV for air quality.
I looked into sips, but the cost factor ruled it out. It would be my choose for new living space. Great idea about using it for the roof. I still have a Garage to build. What kind of cost are these steel sips? I was told by a local sip builder to figure $10 sqft installed plus surface coverings for wood covered sips.
Thanks |

Thanks the advantage over the wood sips is you are kiling several birds with one stone and replacing several components all at once....... insulation, vapor barrier, exterior paint, interior finish/paint, soffit, roof and wall coverings for about the same or slightly higher as wood SIPs

Just completed a 70' x 40' "Versa frame" shop in two weeks, start to lock-up. We used the versa frame as the structural frame for the shop. We then sheeted the sides and roof with 4' x 11' 8" EPS and structural steel panels. The steel embedded in the EPS acted as the purlins and girts and the outside was ready to be cladded. The end product was a R36 insulated shop that was erected sheeted and locked up in less than two weeks. I have attached some photos of the project, if you want more information feel free to PM me.
