Metl-Span’s HPCI Barrier insulated backup panel is an air-, water-, thermal-, and vapor-barrier system that can be used behind façade systems. The High Performance Continuous Insulation panels are single panels (as opposed to a multilayered system), and are available in a 2" thickness with an R-value of 15, and a 3" thickness with an R-value of 22. The panels are installed outside of a building’s structural supports, eliminating thermal bridges that can reduce the efficiency of exterior wall systems. •
