This specialized vapor barrier is constructed from an F/R grade Foil-Scrim-Kraft Facing. It features an aluminum foil and Kraft paper outer layer, laminated with a flame-retardant adhesive to a middle layer of glass fiber. This robust construction increases tensile strength and creates a strong bond between the layers, ensuring a durable and tear-resistant material.
The versatility and effectiveness of this vapor barrier make it essential for various applications across the construction and HVAC industries:
