Vinyl Backed Fiberglass insulation is the most common used product for the typical Pole (or Post Frame) building. The sun’s rays on a steel surface will create extreme heat temperatures inside the building. In addition, the cold winter temperatures react with the metal roof and wall sheeting making it frigid inside. Warm temperatures coming in contact with cool metal roof or walls create sweating. Laid with a white reinforced vinyl backing, our insulation is attractive and economical.
