Nashua 327 Heavy-Duty Foil/Butyl HVAC Sealing Tape – 3" x 100'

Heavy-duty HVAC sealing tape combining aluminum foil with an aggressive butyl rubber adhesive for demanding air- and water-tight sealing applications.

Nashua 327 Premium Foil/Butyl Tape is designed for professional HVAC installations where a heavier-duty sealing solution is required. Its thick foil construction and butyl mastic adhesive conform to irregular surfaces and provide an immediate, durable seal.

Unlike standard HVAC foil tape, Nashua 327 is designed for demanding sealing applications where additional thickness, conformability and sealing performance are needed.
