CFR
Metl-Span’s CFR is an insulated metal roof standing seam panel. This innovative, all-in-one composite insulated standing seam roof panel design combines durable interior and exterior faces with a foam core. The exterior profile is 1/8″ deep embossed planks and can be used on roof slopes as low as 1/2″: 12″.
The CFR composite roof panel’s unique advantage is that it comes with factory-cut panel notching and swaged ends, eliminating the need for additional time-consuming labor. Factory installed backer plates at the endlaps eliminate the need for pre-drilling for special fasteners. Its standing seam exterior face also provides unsurpassed weathertight performance, making it an unmatched roof system.
CFR panels can also function as roofing for coolers, freezers, food processing, and dry goods warehouses. This is the ideal roof panel of choice when temperature control and longevity are critical. Contact our representatives today for more information.
