Sealing pole barn seams

Wildride47 · Oct 8, 2017

One of my fall/winter projects will be building some heated space in the pole barn. I’ve been plugging the gaps in the seams of the siding with stainless steel wool to keep the bugs and mice out. I haven’t figured out how to fill the small gaps where the siding sheets meet the wainscot trim. I’ve read caulking can cause the siding to rust. Has anyone figured out how to stop the rain and snow from weeping through this seam? When I get this issue resolved I’m planning to put up poly sheeting to act as a barrier and protect the insulation in the stud construction

Try spray foam insulation.

I'll second the expanding foam.

But be sparing with it, and be sure the wainscot is firmly attached as it will continue to expand and push the two apart.

If mice are a problem, get the green can, called Pest Block.

If you have 8" patterned panel they make foam
closures. Typically they are cheap. Probably
cheaper then wool. I'd be leary if poly sheet as a
liner. Personally I would use a building paper that
will let the cavity breath more than poly.
