Garage is going to be more of a shop and will always be heated.

Thanks everyone for the replies! Hey Sureshot, my Mom (RIP) was from Rigina Saskatchewan.

Hi All, Haven't found much on this. Please chime in. What about using a common boiler for both the garage floor heat via pex in concrete and house forced air via the boiler feeding a water to air heat exchanger in a air handler? Thanks, Ed

Background: Existing House: Two stories, each floor is 1056sf for a total of 2112sf. Forced air natgas heat with 22 year old furnace. No air conditioning. Planned new Shop/Garage: 1850sf Attached via 20ft of one wall. In floor hydronic heat with boiler. Mini-split for cooling. At some point...

Hello fellow Michigander Trbomax, With foam on the inside you prevent moisture from entering your inner cavity. Insulation on the outside does the same and both add R-Value to your wall. The issue is; how does the inner insulation in your stud wall dry should there be a leak? THis is the...

Thanks all who commented. I am skipping the foam all together. The R-Value of foam is dependant on climate zone, I'm in zone 7, the building code requires r-15 (3" XPS). I could probable get away with 2" of Polyiso (r-13) as we are warmer than most of climated zone 7 but it still makes no...

Big issue of using foam is the wall must dry to the inside. The thicker the foam the less moisture condenses in the wall during the cold months. Think temperature gradiante from 0 outside to 70 inside and were the dew point is in the physical wall. The more foam the less fiberglass is...

I'm using Loopcad 2012. Using wall r-value of 14 (whole wall value), 50 in the ceiling. Planning on 3 8x10 foot Raynor doors-R18 but using R-8 in the program. A couple of man doors using r8 for those. I forget if I had 2 or 3 2x4 double glazed windows. -Ed

Hi All, Designing up an 1800sf garage/shop. I am in the U.P. of Michigan and plan on heating the full space in the winter to 65-68 degrees with natural gas radiant slab. 1. Radiant slab w/2" XPS. 2. Foundation/stem wall w/2" XPS on the inside with the slab decoupled from the stem walls. 3...

Hi All, I would like some opinions on my shop/garage design as related to floor slope. Here is the current plan which is the maximum size I can fit onto my site. 38' wide by 28' deep with 9' ceiling and an addition storage room on the end 14' wide and 20' deep with a 9' ceiling. Will most...
