A friend just installed a pole building, and he’s having an issue with the door jamming, now that the slab is heaving a bit. It seems this builder (who only does pole buildings, and seems to do them by the hundreds per year) tied the jack studs and header that frame the door to the metal siding, which is tied to the poles, sunk in the ground. As the slab moves relative to those poles, specifically as it heaves up toward winter, it pushes up on the door sill and jams the door. I suggested he disconnect the steel siding from the framing around the door, and just capture it to the framing with the door casing, so that the door can move with the slab, independently of the poles and siding. Not sure how others have handled this, but it seems to me pole buildings are not the best option for a fully-finished structure. They’re great for agricultural use, but if going for a fully-insulated and climate controlled structure, I think I’d want to stick to traditional framing.
