Steel siding details...

[mlo1]

I am wanting to use vertical steel siding over 2x6 stick framed walls. The municipality calls for living space insulation codes as the shop will have in-floor heat and plumbing. The back and one sidewall of the shop will be located within 1'-6" of existing 6' fences, allowable zero lot line build. After having hydronic heat before in a mono slab setup, I am really desiring a stem wall foundation to better insulate/isolate the interior slab. It is also important the final 26 x 30 shop blend well with the surrounding wood homes. I find myself stumbling over some details, even after talking with metal building suppliers who really do not seem to be able to offer any input concerning integrating these building methods. My draftsman as well is asking for me to provide him desired details concerning metal siding specifics.

I had planned on stick framing, sheathing, wrapping, strapping, then steel siding. Not wanting to have a large protrusion of the finished wall beyond the foundation stem wall, does one just make the stem wall wider, say the thickness of the 1" strapping? Seems that would allow the use of a typical all metal building protrusion base-molding at the bottom of the steel siding. I really want this detail to be minimalistic and mimic wood T111 or such.

The actual building of two walls in this tight 1'-6" confine is my other dilemma. Not having any steel siding experience, maybe that is sufficient space for a 10' tall siding install though no fun certainly. On a slab I could see the walls being stood up and joined then slid back, but not so much with a stem wall foundation. Any input would much appreciated. I have been watching others on this forum for years and know that others have likely "been there done that!"

TIA

You can save money by only sheathing the corners, and then strapping between the sheathing. I think this is the best of both worlds and is more than plenty strong.

Instead of making the stem wall thicker, I would use XPS foam on the outside of the stem wall.

Thanks for the response ishiboo...I understand just sheathing the corners. But does one just double the sheathing as to equate the thickness of 1" strapping for a seamless transition or am I missing something here?

I used insulboard around my last mono-slab. The uv rays broke it down over a handful of years and naturally it also did not blend with the typical concrete foundation of other close structures. I was not entirely happy with the insulation level it offered as the moles and mice loved it within 5' of the building through the cold months. I have been trying to find a schematic of a foundation detail that involved a kerf formed into the stemwall for the steel siding to protrude down into on install. Certain I saw on this site but have been unable to dig it up.

Should anyone know of a builder/contractor guy near Seattle that would be interested in such a project, some contact info would great.
