DeltaTrimTrim

Designed for low-pitch roofing with exceptional span and cantilever capabilities

ARCPANEL DeltaTrimTrim is a lightweight insulated roof system designed for commercial and residential applications where low-pitch performance and a consistent architectural profile are required.

Available with EPS-FR or TPC insulated cores, DeltaTrimTrim provides a choice of performance characteristics to suit different project requirements, including an FM Approved TPC option.

With Trimdek profiles to both the roof and ceiling sheets, the system delivers a clean, uniform appearance while combining roofing, insulation and ceiling in one integrated panel.

Its long-span and cantilever capabilities can reduce the need for complex supporting structures, while lightweight panel construction helps simplify installation and reduce construction time.
