Replace Insulation In Pole Barn Roof

If the insulation has aged like this the roof would benefit from new fasteners.

Replace insulation in pole barn roof.

Here the insulation is placed between the inner purlin supported by the truss and the outside metal panel. One is to remove the panels remove the old insulation and replace it with new insulation. R values indicate the insulative properties of the material used. However barns are colder than other buildings and may require more insulation.

This will provide a greater r value than r19 batts and provides a vapor barrier. When the old panels are removed new larger fasteners are used to put it back together. Weighing what you have to start with my recommendation is to spray three inches of closed cell foam insulation below your roof sheathing. One or two inch insulation can be placed on the exterior of the building underneath the steel.

Pole barn insulation thickness one or two inches. Steel roofing is a highly conductive material in terms of heat transfer. Closed cell spray foam insulation would need to be added in the area closest to eave sidewalls. The fiberglass insulation used in this method can be as high as r 13 insulation thickness on single layer systems range from r 7 to r 30.

Pole barn or post frame buildings are typically constructed using wood framing with steel roofing and siding. Depending on the type of barn your requirements may vary. It ranges from r 5 to an r 16 value depending on the type. If it is a barn for keeping animals in insulation is much more important.

Insulating a barn roof is very similar to insulating any other kind of building. Above the roof trusses this choice comes with new construction or a roof replacement.
