Flanges & Corners
Matched roll-formed flange profiles and corner pieces for accurate, repeatable rectangular duct joints.
System-compatible access panels that preserve the tested fire-rated duct enclosure while enabling inspection.
A standard access door can invalidate a fire-rated duct assembly. Fire-rated access systems use tested panels, frames, fasteners and seals compatible with the protection method. Indigo Sky coordinates location, opening size and installation with the approved duct system so inspection access does not become an unprotected weak point.
Typical construction information for early coordination. Final values are governed by the selected model, approved material and project design.
