    How to Insulate a 30×40 Metal Building

    There are two way to insulate a 30×40 Quonset Metal Building using the Full Quonset Style Design. Traditional fiberglass insulation can be purchased and used to enclose the structure and is available in 3″, 4″ & 6″ thicknesses. When insulating the inside of a steel arch building, pins are attached to the bolts on the arches. The insulation pin is pushed through the fiberglass insulation and a washer is attached holding the insulation blanket in place. These pins are specifically designed for arch building insulation and are available at an additional cost.

    The most popular method for insulating a metal building is the use of spray foam. The applied foam is made up of two materials, polyurethane and isocyanate. When these two compounds react, they expand and harden in place which is perfect for getting into small crevice’s and cross spaces. Spray foam also has a high R-Value which reflects and protects against extreme heat.¬†
