Certificate holder: Marshall Innovations Ltd.

Maxi-Butyl Flashing Tape is a tear-resistant, UV-stable, pressure-sensitive flexible flashing tape manufactured from a butyl rubber copolymer. It is available in 75 mm, 150 mm, and 200 mm widths on 23 m rolls.

Maxi-Butyl Flashing Tape is intended to be used as a self-adhesive flashing tape around window and door joinery openings as a secondary water-resistant barrier. It is used to seal junctions between framing and wall underlays, and to provide weather protection at sill, jamb, and head interfaces. The 75mm width may also be used to form corner “butterflies” and as a head flashing tape.
