CENTRIA MetalWrap Insulated-Composite Backup Panel System with Integrated Windows and Louvers

CENTRIA MetalWrap Insulated-Composite Backup Panel System with Integrated Windows and Louvers CENTRIA MetalWrap Insulated Composite Backup Panel System is designed to be used with CENTRIA Formavue FV-600 windows to create a complete backup wall solution for metal wall panel, brick, or terra cotta rainscreens. The unique composite design of MetalWrap provides an air barrier, moisture barrier, and thermal insulation with total wall values up to R-21 in a single, easy-toinstall component. MetalWrap eliminates the need for separate batt or board insulation, sheathing, air barriers, vapor retarders, and building wraps, while providing greater thermal efficiency and moisture control. MetalWrap is designed for use with vertical or horizontal exterior cladding installations, including Profile Products and FormaBond. MetalWrap was developed using ATMP - CENTRIA's Advanced Thermal and Moisture Protection building envelope science; it maximizes a metal wall system's ability to effectively control moisture without sacrificing thermal efficiency. Metal panel wall systems utilizing MetalWrap with steel stud construction and interior gypsum board finish are available with overall wall thermal resistance of R-14 (for 2-inch thick MetalWrap) and R-21 (for 3-inch thick MetalWrap). Formavue FV-600X & FV-600A windows are designed to integrate with the MetalWrap assembly and with CENTRIA metal wall panels to provide a single-source solution to building enclosure air, vapor, and moisture control.
