Firestone New Product: ISOGARD HD Composite

Two years ago Firestone pioneered ½” high density polyisocyanurate cover boards. By providing a rigid and durable, yet light-weight and easy to cut, cover board with an R-value of 2.5, Firestone truly revolutionized the cover board market.  Utilizing this proven technology, Firestone is pleased to take ISOGARD HD to a new level with the ISOGARD HD Composite.

ISOGARD HD Composite consists of a ½” ISOGARD HD cover board laminated directly to Firestone’s standard ISO 95+™ GL polyisocyanurate insulation. By combining these two proven products, in an in-line manufacturing process, the building owner receives a high performing, energy efficient insulation board, while the installer saves time and labor during installation.
