Types Of Pole Barn Insulation

The type of insulation you choose for your pole barn will depend on your specific needs and expected results for your project.


One factor that can help you assess different types of insulation is the R-value of each. This index measures the insulation’s ability to resist heat transfer. The higher it is, the better results you can expect.


Some of the most common types of pole barn insulation include:


Fiberglass Insulation


Fiberglass comes in batts, rolls or loose-fill.


Fiberglass is a popular insulation option because it combines affordable pricing with easy installation.


If you opt for fiberglass insulation, we recommend using foil fiberglass vinyl for your pole barn. It offers the benefits of foil faced insulation, including the ability to increase energy efficiency, provide soundproofing and repel pests.


Spray Foam Insulation


Depending on whether it’s open-cell or closed-cell, spray foam offers different thermal and water-resistant characteristics. Its R-value ranges from 3.7 to 6.5 per inch, depending on the thickness, density and type.


Spray foam insulation prevents the nesting of rodents, bugs and birds. However, it is not effective as a condensation and vapor barrier and it does not seal well around punctures.


Prodex


Prodex is a revolutionary all-in-one solution for numerous pole barn issues like heat, cold, condensation, mold, mildew and noise disturbances that are multiplied by the metal roof.


Prodex includes a reinforced reflective foil that is unattractive to pests and prevents them from nesting in your structure.

How To Insulate A Pole Barn With Prodex: Equipment Checklist

Already decided on Prodex? Congratulations! You will benefit from a fast and easy installation process and a short and concise equipment list.


To insulate your pole barn with Prodex, you will need:


  • Reflective tape
  • Double-sided tape
  • A staple or screw gun
  • A utility knife

The reflective tape can be used to seal seams to create a vapor barrier.


The double sided tape can be used to hold the insulation in place during install and keep it safe from the wind.


To cut pieces of insulation, use your utility knife and fasten them with the help of the screw gun.

How To Insulate A Pole Barn With Prodex


By hiring professionals, you can ensure your insulation is installed properly from start to finish. But if you want to install Prodex on your own, you can follow our step-by-step guide for both new construction and retrofitting applications.

New Constructions: Roof/Wall Insulation Over Purlins


Recommended Prodex type: 48 Inch, Fast Action, 10M, 72 Inch, White, Rustic


Alternative insulation: Reflective bubble reflective or foil fiberglass vinyl


Prodex insulation on new construction over purlins
  • Put double-sided tape on the top of the framing to keep the insulation in place against wind.
  • Roll the insulation perpendicular to and over the frames.
  • Push the insulation in to create an air gap of a minimum 2 inches. This air space will act as an additional insulation layer and add to better efficiency. Note that if you are using two layers of insulation, your air gap should be bigger to maximize performance.
  • Tape seams with reflective tape.
  • If you want to avoid taping, use 10M or Prodex Fast Action.
  • Attach your sheeting.

New Constructions: Roof/Wall Insulation With Two Layers Of Prodex


Recommended Prodex type: 48 Inch, Fast Action, 10M, 72 Inch, White, Rustic


  • Use double-sided tape to keep the insulation in place.

  • Attach the insulation perpendicular to and over the frames.
  • Use reflective tape to bind seams.
  • Take advantage of 10M or Prodex Fast Action’s adhesive line if you want to avoid the taping process.
  • Fix your sheeting.
  • Screw the insulation to the underside of the purlins with wide-head screws every 3-4 feet.
  • Run the insulation perpendicular to the purlins — a 72 inch or 48-inch-wide roll will work regardless of the width between your purlins.

Retrofitting: Roof/Wall Insulation With Or Without Existing Insulation


Recommended Prodex type: 48 Inch, Fast Action, 10M, White, Rustic or 72 Inch


Alternative insulation: Reflective bubble reflective or foil fiberglass vinyl


  • Screw the insulation to the underside of the purlins.
  • Reinforce it every 3-4 feet with wide-head screws.
  • Run the insulation roll perpendicular to the purlins; therefore, it will fit any width.

Retrofitting: Roof/Wall Insulation Between Girts (one or two layers)


Recommended Prodex type: 10M, 48 Inch, Fast Action, 24 Inch, 16 Inch, White or Rustic


  • Screw the insulation between the frames.
  • Leave an air gap a minimum of 1 inch between the insulation and the sheeting to optimize performance.

Pole Barn Insulation Tips

Ready to begin the installation process?


Whether you choose fiberglass, spray foam or Prodex for insulating your pole barn, our tips will help give you more confidence to approach the process. Here are our top tips to keep in mind for your project:


  • Plan your pole barn insulation in the design phase. Remember that well-engineered walls facilitate insulation. Use columns that are placed 8 to 10 feet apart instead of the typical 2 feet with stud wall systems. Eliminate obstructions that might hinder insulation performance.
  • Choose your insulation based on the use of your pole barn. Do you use it for storage, work, recreation, to house animals or something else? Keep weather conditions in your location in mind as well.
  • If you are using your pole barn for animals, consider roof insulation instead of wall insulation. Animals generate a lot of heat and additional humidity, and heat is lost largely through the roof of a structure. Focusing on decreasing moisture and keeping the pole barn cool may be a worthwhile investment to make sure your animals are comfortable, safe and living in a healthy environment.
  • Insulating the roof of your structure can also help ensure the temperature inside does not reach the dew point, which will prevent condensation and its consequences – mold and mildew.
