The phrase "What a cluster-%$!# !" was going through my head constantly while it was nodding back in forth in pity and I had to resist the urge to simply hit "Delete". (Trying to minimise needless headaches in my old age. Eh ?)</div><div><br></div><div>I'm wondering if there's enough room to add insulation to the inside of the steel framing -- enough so that the dew point of any moisture piggy-backed on air leakage from the conditioned interior is far, far away from the steel framing ? The current vapour barrier would need to be removed of course since it'd be at the wrong location. The reasoning is that it's probably easier to add to the interior to accommodate the additional insulation than it is to try and wrap the outside of the existing structure to eliminate all of the massive thermal bridges and mistakes in detailing.</div><div><br></div><div>It sounds like the structure is basically an agricultural implement storage shed. If that's the case, perhaps the approach may be to build properly insulated/air-sealed autonomous "modules" inside of the steel structural shell -- ie modules that include insulated floors, walls and ceilings.</div><div><br></div><div>And if it is in fact an agricultural setting, perhaps this would be an opportunity to utilise straw bales (or other cellulosic material (ie wood chips, ag waste fibre etc) made into building blocks for the shells of the modules ? This would be something the homeowners could do themselves since I'm guessing their building budget has taken a severe hit with the cluster-$%@# that they're dealing with now.</div><div> </div><div>
