I am looking for advice for insulating an existing pole building on my property. At this point, spray foam (which I would prefer) is out due to the cost locally. The building appears to be fairly standard pole barn construction with horizontal girts 24" oc on the walls. Trusses are 48" oc. Currently there is no insulation in the building although both the garage and man door are insulated. The building does not need to be up to living temps, just warm enough to keep food jars and what not from freezing during winter. Any suggestions?
