Superstick uses a pressure-sensitive adhesive and toughened film, and installs down to -6°C. Superstick is compatible over James Hardie rigid air barrier (RAB), and its UV rating is 90 days, or 180 days over James Hardie RAB. Maxi-Butyl suits jobs with longer exposure and simpler single-layer sill work. Superstick suits cold-weather installs and James Hardie RAB projects.
