How do you insulate an old pole barn?

Last Updated: 23rd June, 2020

26
There are many pole barn insulation options. One could use foam board, fiberglass or spray foam. I used 1 1/2" foam board between the purlins and then built a 2x4 stud wall between the posts to use 6" R-19 fiberglass insulation. I use 2x4s instead of 2x6s to provide a thermal break between the stud and the purlins.

Beside this, how do you insulate an existing pole barn?

One option is a light spray foam (about 1") on the inside of the siding and along all the edges of the studs. This will act primarily as a vapor barrier so it is important that it seals all the cracks. Then you can install roll fiberglass insulation or "wet" spray on cellulose (fast and not too expensive).

Similarly, what is the cheapest way to insulate a pole barn? It is easy to cut, but making any adjustments with cuts or compressing will make it less effective and provide little resistance to the airflow. Fiberglass can cost up to $1 per square foot depending on the R-value and the thermal resistance one is looking for. Another option is to use spray foam insulation.

Also question is, should I insulate my pole barn?

Insulating A Pole Barn Numerous types, R values, and product quality. Using the right installation is incredibly important. If you have the money, professionally sprayed on foam insulation is the absolute best option but is very expensive. This type of insulation should be covered since it is very flammable.

How much does it cost to insulate a pole barn?

The projected cost to insulate a pole barn varies between $8,000 and $20,000 depending on the size of the structure and the area that needs to be insulated.

Can I spray foam insulation myself?

A: Tom Silva replies: Spray foam is great insulation, but it's fairly demanding to apply; the kit instructions have to be followed exactly. In fact, study them before you buy your kit so you know what you're in for. As with spray-foam kits, protect yourself and the floor from the dripping globs of canned foam.

How do you cool a pole barn?

Use Air Conditioning
You should also insulate your pole barn to keep the cool air indoors. You can install bookshelf girts, or horizontal planks, between the posts of the outside walls. This will allow you to create pockets to hold the insulation and will also give the building support for drywall.

Is foam board insulation better than fiberglass?

Higher R-values indicate better insulating values. With both rigid foam and fiberglass, the R-values are mostly determined by the thickness of the insulating material. Fiberglass insulation packs in more R-value per cubic inch than does rigid foam insulation.
