2 mil (50 micron) Aluminum Foil Tape

A high strength aluminum foil coated with special cold weather acrylic adhesive system that combines quick stick at normal temperatures with low temperature performance at freezing (32°F / 0°C).The foil conforms well to both fibrous and sheet metal ducts, providing an excellent vapor seal. The malleable foil also conforms well around corners and to irregular surfaces. 

Application: Improved vapor sealing of fiberglass ductboard, ductwrap and FSK systems
