Pole Barn Insulation

Insulating A Pole Barn
Pole barns are built for durability, but how you insulate them can make or break their long-term performance. Choosing the right insulation isn’t just about comfort. It’s really about controlling moisture, cutting energy costs, and protecting the people, animals, and equipment inside. At CMI, we offer smart, cost-effective pole barn insulation solutions that are built to match the strength of your structure.
What’s the Best Way to Insulate a Pole Barn?
Pole barns can serve a variety of functions. So, everything from farm storage and workshops to animal shelters and event spaces. Pole building insulation plays a huge role in how well your barn works throughout the year. At CMI, we offer three reliable options to meet different needs and budgets:
- Faced Fiberglass Blanket Insulation
- Polyisocyanurate Rigid Board Insulation
- Radiant Barrier Insulation – LOW-E https://low-e.com/
Each has its place, and we’re here to help you choose the right fit for your barn.
Pole Barn Insulation Options
There are a few types of insulation options commonly used for pole barns. One of those methods is spray foam. While this choice is widely accepted because it can seal corners and cracks and those oddly shaped spots that air creeps in through, it is also the most expensive choice. And we all know cost plays a big role when deciding which insulation method to purchase.
CMI offers two other insulation options for pole barn owners — faced fiberglass blanket and polyisocyanurate board insulation — both of which are very cost-effective.
Pole Barn Faced Fiberglass Insulation Blankets
This is a go-to option for metal buildings. Faced fiberglass blanket insulation is easy to install, affordable, and excellent at controlling heat flow. The added facing acts as a vapor barrier to help reduce condensation and moisture damage, common culprits in uninsulated barns. Ours is Class A fire-rated and formaldehyde-free. This makes it safer for livestock, workers, and machinery.

Pole Barn Polyisocyanurate Rigid Insulation Boards
Polyisocyanurate board is a type of rigid foam insulation for exposed applications, and tends to be used when a flat sheetrock-like look is desired. This type of pole barn insulation is offered in varying thicknesses, lengths and facings. Polyisocyanurate insulation has a white foil vapor barrier on each side of the material that keeps water from traveling into the walls of your pole barn that could cause mold and structural deterioration.
So no matter the size, style or use of your pole barn, CMI provides an array of pole barn insulation options perfectly suited and priced for your built to last structure.
Pole Barn Insulation Frequently Asked Questions
Does my pole barn really need insulation?
If you plan to spend any time inside your pole barn or store anything sensitive to moisture or temperature, pole building insulation is a must-have. It helps regulate the environment, improves the lifespan of the building, and makes it more functional.
Can I install fiberglass insulation myself?
Yes! Faced fiberglass blanket insulation is designed with easy installation in mind. With just basic tools and a little prep work, many barn owners choose to DIY. If you’re not sure, we can help you find a contractor.
How do I choose between board and blanket insulation?
Blanket insulation is ideal for simple structures where budget is a top concern. Polyiso boards are better when you want higher thermal performance and a finished appearance. We can walk you through the pros and cons based on your project, though.
