CENTRIA Versawall Factory Foamed Metal Wall Panel System

Transcription

1 CENTRIA Versawall Factory Foamed Metal Wall Panel System Often recommended for industrial applications, the CENTRIA Versawall Factory Foamed Panel System is also often used for low- and mid-rise buildings where style, economy, and good insulation values are important -- such as for shopping centers, schools, and warehouses. The Versawall System is especially well suited for high humidity conditions, highly insulated structures, and buildings where long spans are required. Versawall panels are steel-faced, pre-finished, foamed-in-place, insulating wall panels with double-interlocking side joints, integral vapor seals, and concealed structural fastening. The Versawall Panel System is available as an embossed panel with a subtly striated exterior surface. Panels are available in Kynar 500 or Hylar 5000 polyvinylidene fluoride (PVDF) finishes, including micas and metallics. Highly UV resistant and durable in the face of chemical and air borne pollution, salt spray and wind-driven sand, PVDF coatings are the Gold Standard of the architectural exterior industry. CENTRIA Versawall systems are available in over 60 standard colors, and wide array of custom colors. Versawall panels are also available in CENTRIA s Duracast natural aggregate-textured finishes. Consult your local CENTRIA architectural representative for design assistance. Contact CENTRIA, Pittsburgh, PA, (800) , info@centria.com, for a list of offices.
