Is fiberglass good for pole barns?

It can be, when faced blanket goes in during construction with every seam sealed. In an existing barn, closed-cell spray foam is usually better.

What R-value is pole barn blanket insulation?

Common choices are about R-13 for walls and R-19 for the roof.

Do I need a vapor barrier with fiberglass?

Yes. The facing is the vapor retarder and must be continuous and sealed.

Can fiberglass go in after the barn is built?

Only by removing panels or adding a liner, which is why spray foam is usually used on existing barns.

How much does fiberglass pole barn insulation cost?

Faced blanket typically runs about $1.00 to $2.00 per square foot installed during construction.

Do mice nest in fiberglass?

Yes, often. Sealing the base trim and using a liner helps.

Is foam board an option?

Rigid foam board works in some framed walls but needs every seam sealed. We can price it alongside blanket and spray foam.

Fiberglass Pole Barn Insulation Tulsa, OK

Fiberglass is still the lowest-cost way to insulate a pole barn when it goes in at the right time. Faced metal building blanket, a fiberglass roll with a vinyl or reinforced facing, is laid over the purlins and behind the wall panels while the building is being put up. Done right, it gives solid R-value at a lower price than spray foam.

The catch is that fiberglass does not stop air or moisture by itself. The facing has to be continuous and sealed at every seam, or humid air gets behind it and condenses on the metal. Fiberglass that has been wet, torn or pulled down by rodents loses most of its value.

We install faced blanket on new buildings and fiberglass batts in framed walls and ceilings, and we tell you honestly when spray foam would be the better choice, such as an existing barn where panels would have to come off.

Tulsa tip

Fiberglass works best when the building is still open. If your barn is already built and the panels are on, adding blanket insulation means removing panels, and closed-cell spray foam is usually the better value.

When Fiberglass Makes Sense

✓A new pole barn going up soon
✓A tight budget for a large building
✓Framed interior walls or ceilings
✓A liner or interior panels planned
✓Low humidity use like dry storage
✓Replacing torn blanket during a reroof

Choosing an R-Value and Facing

Common metal building blanket thicknesses are about R-13 on walls and R-19 overhead. A heated shop may use thicker blanket or a liner system with more insulation.

The facing is the vapor retarder. Reinforced vinyl or polypropylene facings with taped seams hold up better than thin films, and every tab and seam must be sealed.
