Project File - Pole Barn Insulation – New Jersey

Who: Customer

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.
