Replace Insulation In Pole Barn Roof

Pole barn insulation thickness one or two inches.

Replace insulation in pole barn roof.

Here the insulation is placed between the inner purlin supported by the truss and the outside metal panel. If it is a barn for keeping animals in insulation is much more important. To repair it there are two primary methods. Weighing what you have to start with my recommendation is to spray three inches of closed cell foam insulation below your roof sheathing.

R values indicate the insulative properties of the material used. In a non insulated pole barn there will be a large amount of heat transferred in and out. Steel roofing is a highly conductive material in terms of heat transfer. When the old panels are removed new larger fasteners are used to put it back together.

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. One is to remove the panels remove the old insulation and replace it with new insulation. Above the roof trusses this choice comes with new construction or a roof replacement. 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. Depending on the type of barn your requirements may vary. It ranges from r 5 to an r 16 value depending on the type. Closed cell spray foam insulation would need to be added in the area closest to eave sidewalls.

Pole barn or post frame buildings are typically constructed using wood framing with steel roofing and siding. Insulating a barn roof is very similar to insulating any other kind of building.
