Metl-Span’s new HPCI Barrier insulated metal panel is an air, water, thermal and vapor barrier panel that can be used behind virtually any type of façade. The HPCI (High Performance Continuous Insulation) Barrier back-up panels are available in 2- and 3-inch thicknesses and provide R-values of 15 and 22 respectively. It is a single panel system that controls air, water and vapor without sacrificing thermal efficiency. The panels are installed completely outside the structural supports and there are no thermal bridges to reduce the energy efficiency of the wall. HPCI Barrier is quick and easy to install and provides an economical solution to conventional air, water, thermal and vapor control.
