You're right, it doesnt look like any load was designed into the bottom chord. Im thinking of putting up a few scabs, then my only option really would be a metal ceiling, and fiberglass blown in insulation.
The estimate for 2-inch closed-cell spray foam on the walls and roof came in at nearly the same price as constructing an entirely new pole barn of the same size.
I’m also looking into what’s required to add vented soffits to the barn. Right now, I’m exploring both retrofitting the existing soffits and doing a full replacement.
I believe that with some F-channel, new fascia trim, and vented soffit panels, it should be achievable.
I’ll likely need to...
This aligns with what Readhead mentioned, and he’s correct—I misspoke earlier. I don’t believe I have MBI; I believe there is a thin vapor/condensation barrier between the wall and roof panels. I’m currently researching this new information.
That said, it still seems that adding anything sealed...
How can I help answer these questions for you? I’d be happy to track down the information so I can get better advice.
The material on the walls is white and looks like bubble wrap. I can’t find any numbers, branding, or wording on it anywhere.
I haven’t been able to inspect the ceiling much...
That looks sharp—I really like the metal.
I have a few questions for you:
What climate zone are you in? Midwest?
I noticed some type of wrap between the girts and the siding. What is it, and do you plan to insulate the walls?
Your ceiling appears to be vaulted and follows the roof pitch. Is...
Good advice—I appreciate you walking me through it. I like to have everything figured out before spending a bunch of money installing something the wrong or inefficient way.
I had to reread your posts, and I think I understand now. For the walls, you’d install polyiso between the girts, with unfaced fiberglass insulation over top then osb. For the ceiling, you’d also use polyiso board along with the unfaced fiberglass insulation and OSB—is that correct?
I might be...
You mean leaking through the ceiling and allowing the insulation to fall into the shop? My plan for the ceiling base is to use rigid metal panels. For the walls, I’ll be using OSB with polyiso insulation.
That’s the plan. I’ll be doing blown-in insulation above the ceiling. My first step is to vent the soffits and install baffles. The challenge is that the barn builder installed a custom soffit—what I’m calling a solid soffit. It looks like they either rented a brake or had their own and bent the...
I ran the calculations on this. With 4" vents, it would take 72 of them (total for both sides) to achieve sufficient airflow—basically one vent spaced about every foot.
I don’t believe they’re sealed, but I’ll take a closer look today to confirm. As it stands now, my plan is to install F-channel, then vented soffits, followed by a capped fascia trim to secure the outer edge of the soffit.
Any good suggestions on how to convert this solid soffit to a vented one? It looks like retrofitting J-channel could be tricky, since the fascia board and the top girt sit at different elevations.
Im not 100% sure but I believe this is the type of construction I have.
Or it could be this...
Thank you for the tip. I’ll look for a local manufacturer. I’m really glad I found this forum—you’ve all been a huge help and a great source of inspiration.
