Project File - Pole Barn Insulation – New Jersey
What: Insulate Pole Barn
Why: Minimize radiant heat gain and loss. Prevent condensation
Where: Somerset County, New Jersey
How: Insulated roof over purlins. Insulated walls on the inside of the girts between the posts.
This is a new construction post and frame barn with great installation pictures sent it by a customer. The pictures illustrate two typical installation methods when using reflective foil insulation. For the roof, the insulation was installed “over the purlins” which can only be done in conjunction with a new construction install or removing/replacing the metal roof. The insulation for the walls is installed “inside the girts” vertically from post to post. This can be done in new construction or retrofit applications.
Picture 1: A look at the large side wall and gable area. You can see the reflective foil installed over the purlins.
Picture 2: A look at the trusses and roof. In retrofit applications the insulation can be installed “under the purlins” or “under the truss”.
Picture 4: Showing the installation of the insulation on the walls. The insulation was installed vertically and attached to the girts. 4’ wide material was used for this job. Note this seams where the insulation meets are taped to provide a vapor barrier.
Picture 5: Foil insulation installed to girts and rolled slightly and attached to posts. Seams taped at center.
Picture 8: Insulated side wall. 48” x 100’ InfraStop foil double bubble insulation used for project.
