THERMAX™ White Finish Polyisocyanurate Insulation | 2.5" x 4' x 8' | R-16
Upgrade your building's efficiency and appearance in one step. THERMAX™ White Finish is a non-structural, rigid board insulation consisting of a glass-fiber-reinforced polyisocyanurate foam core sandwiched between two layers of aluminum foil. The exterior-facing side features a heavy-duty, embossed white acrylic-coated aluminum finish, providing a clean, bright, and durable interior surface that can be left exposed.
Key Features
High Thermal Performance: A 2.5-inch thickness provides an impressive R-16 value, significantly reducing energy costs.
Finished Interior Look: The embossed white surface is washable and light-reflective, making it ideal for warehouses, cold storage, and mechanical rooms.
Fire Safety: Features a reinforced PIR core for enhanced fire performance and is UL-rated for use in many wall and ceiling assemblies without a thermal barrier.
Moisture Resistance: The foil facers act as a built-in vapor retarder, preventing moisture drive and protecting the building envelope.
