Insulation and Heating

Insulating your pole barn and installing a heating system can make it more comfortable and functional. Consider using spray foam, fiberglass batt, or rigid foam insulation to improve energy efficiency. For heating, opt for a propane, natural gas, or electric system, depending on your location and availability.
