CENTRIA Formawall® Dimension Series® Insulated Core Metal Wall Panel System
with Integrated Components


CENTRIA Formawall® pressure-equalized insulated core metal wall panel system is designed as a complete wall solution. Formawall® provides an air, water, vapor, and thermal barrier with total wall insulation values up to R22 in a single, easy-to-install finished system. Formawall® eliminates the need for separate batt or board insulation, gypsum board sheathing, air barriers, vapor retarders, and building wraps, while providing better thermal efficiency and moisture control for exterior metal-clad walls.

Formawall® systems include optional integrated windows, translucent fiberglass sandwich panels, louvers, and sunscreen components with compatible trims and finishes. The optional integrated through-tube system of structural supports can eliminate the need for separate metal stud supports while providing a finished interior solution.

Formawall® was developed using ATMP® - CENTRIA's Advanced Thermal Moisture Protection building envelope science. This exciting product maximizes a metal wall system's ability to effectively control moisture without sacrificing thermal efficiency. Through extensive research and testing, the energy and cost savings of Formawall® have made it a choice for architects globally. Rainscreen design, streak-free dry seal joinery, exceptional panel flatness standards, and high-performance finishes - everything about Formawall® and the CENTRIA network of experienced installers assures the architect of complete satisfaction in the finished project.

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 Formawall® wall systems are available in over 60 standard colors, and wide array of custom colors. CENTRIA Formawall® panels are also available in stainless steel.

A companion guide specification is available from CENTRIA for projects that do not require either CENTRIA's integrated windows, walls, translucent panels, louvers, and/or sun screen units in a Formawall® application.
