The Best Ways to Insulate a Pole Barn

Standard rolled insulation that is used in the ceilings of houses is also good for a pole barn's ceiling and walls. Choose an insulation with an R-rating that fits your specific application. The higher the R-rating, the thicker the insulation, but it's also more expensive. Fiberglass roll insulation will prevent air drafts from entering from the seams as well as keep heat within the barn. A vapor barrier is required or moisture will build up and cause mold within the insulation.

Insulation board is made from hardened foam insulation pressed between two sheets of waterproof reflective coating that prevent mold from forming. This material cuts easily, allowing it to be placed into almost any space. These boards can be used to insulate the roof and walls by gluing them to the sheet metal or studs. The product comes in standard 4-by-8-foot sheets in various thicknesses. Owners can layer the product to increase the insulation where needed.

Spray insulation offers insulating power with ease of installation. The product is sprayed directly on the walls and ceiling, creating a vapor barrier and sealing any air leaks. Cover all plumbing and electrical conduit with plastic sheeting to prevent the foam from penetrating any cracks. The spray foam's insulation rating depends on the thickness that is applied.

A pole barn's windows and doors leak air and lose heat. Seal all doors with weather stripping and attach a door sweep to the bottom, which will prevent air leaks between the frame and door. Caulk all windows and doors with an all-temperature caulk where the frame meets the studs or sheet metal and along the bottom seal plate of the door. Quality insulated glass windows and solid insulated exterior doors will also prevent heat transfer.
