Fiberglass insulation boards can offer multiple benefits for your next mechanical insulation project. Glass fiber insulation boards help save energy by reducing heat transfer, which can assist in lowering operating costs. The 700 Series® insulation boards are available with ASJ Max facings, which have a smooth, durable, and easy-to-clean polymer-film exterior to resist water staining and prevent mold or mildew growth. ASJ Max can also withstand brief exposure to liquid water during construction without damage. Additionally, our rigid fiberglass insulation boards maintain their structural integrity, assisting in long-term efficiency, and contributing to reducing sound transmission. Best of all, even with their durability, their lightweight and resilient nature makes them easy to handle and work with at construction sites.
