DeltaTrimCorro
Designed for low-pitch roofing with exceptional span and cantilever capabilities
ARCPANEL DeltaTrimCorro is an insulated roof system designed for commercial and residential applications, combining roofing, insulation and a pre-finished ceiling in one integrated panel.
Available with EPS-FR, TPC or Mineral Wool (MW) insulated cores, DeltaTrimCorro offers a choice of performance characteristics to suit different project requirements, including an FM Approved TPC option and a mineral wool core option for projects where core combustibility is a key consideration.
Low-pitch options from 2° are available within the range, alongside a clean architectural finish suited to contemporary roof designs. Minimum roof pitch, thermal performance and spanning capabilities depend on the selected core and panel thickness.
Depending on the panel specification and project design, spanning and cantilever capabilities can reduce the need for supporting structures, while prefabricated construction helps simplify installation.
