Why Insulate a Pole Barn? 

Pole barns are incredibly budget-friendly and can be put up in a very small amount of time. They have durable construction and are usually all-steel so you can depend on them in bad weather. However, they are not the most insulated or air-tight structures in the world. Because of this, you will have to insulate a pole barn if you want to live in or spend a lot of time in it. 

When you insulate a pole barn, you have a few different options to choose from. With the right insulation, you would never know that your home or business was built differently. You can spend all year in it and get the same climate control you would get from a traditional home. This means that you could turn your pole barn into your dream home. 

Ways to Insulate a Pole Barn

When you insulate a pole barn, you are doing more than making it comfortable on the inside. You will also be creating a protective layer that will keep your barn in good condition for a lot longer. With the right insulation, you can be sure that things like humidity and extreme cold won’t cause damage. When you insulate a pole barn, you are essentially protecting your investment. 

While insulation is important no matter what, it is even more important to choose the right insulation. Depending on how you are going to use the building, one type may be better than the others. Knowing the upsides and downsides of each type will help you make the right choice. By using the proper methods to insulate a pole barn, you can count on it for many years. 

Foam Board Insulation 

Foam board insulation is one of the most common ways to insulate a pole barn shop or shed. These boards come in varying thicknesses and cover up the exposed walls of the barn. They are made from polystyrene and are known to be one of the cheapest ways to insulate a pole barn. If you are only going to be using the barn in good weather and want to save money, they are a good choice.

The downside of using foam board to insulate a pole barn is its effectiveness. Some of the other methods are going to be much more effective and will offer better protection. While foam board is great for keeping out moisture, it is not going to keep the air inside. If you are going to be living in the pole barn, you will want to use one of the other options. 

Fiberglass Insulation 

Fiberglass insulation is what is most commonly used in traditional houses and homes of all types. It packs nicely in between framing and drywall and is a great alternative to more expensive insulation. It is also a good choice if you need to insulate a pole barn. Most people can install it themselves and it is relatively cheap compared to other types and methods. 

One of the biggest downsides of using fiberglass to insulate a pole barn is the lack of moisture control. Fiberglass insulation is incredibly porous and will do little to keep water out of the building. Because of this, you will have to do some additional weatherproofing if you want to protect the home. This can add expenses and may offset the lower price of the fiberglass insulation. 

Spray Foam Insulation 

One of the most high-end ways to insulate a pole barn is to use spray foam insulation. This type of insulation is a closed-cell foam that is pumped in between the exterior wall and drywall. If you are going to be living in the pole barn, this is the absolute best way to insulate it. It offers high levels of protection and is incredibly durable for long-term use. 

The biggest downside of using spray foam to insulate a pole barn is the price. Spray foam insulation is incredibly expensive and will be a major expense for the cost of the barn. That being said, it could potentially save you money on repairs down the line. Its high level of protection means your pole barn will last for many years. 

Which Way to Insulate a Pole Barn is Best? 

If money is no object, the best way to insulate a pole barn is to use spray foam. Not only is it durable and water resistant, but it is also quite easy to create a tight seal. This means that you will have the highest level of protection, and it will last a long time. If you are going to be living in the pole barn, these are important considerations.

Fiberglass insulation will be your best bet if you need to save a little bit of money. It may not offer the same level of moisture protection, but it is incredibly cheap. These savings can be passed on to other parts of your pole barn build. With the right extra weatherproofing, the lack of moisture protection may not be a problem. 


By understanding the best ways to insulate a pole barn, you can protect your home or shop. Going through these few options and picking the one that works best for you is essential. With the right planning and preparation, your pole barn will be comfortable and dry. Then, you can focus on making it your perfect home or shop.
