Now, with CENTRIA’s reformulated insulating foam core, you can specify Formawall with more confidence for life safety than ever before.


Formawall has always scored well in every applicable ASTM and NFPA test. But CENTRIA went above and beyond to meet the evolving sustainability and performance needs of our customers. The industry’s best insulated metal panel system just got better. For decades, the halogens chlorine and bromine have been added to foam insulation as flame retardants. But with the latest advances in chemistry and material science, there’s a better, even healthier way.


A victory for health, safety, and sustainability, Formawall’s new foam insulation formula now contains zero halogens, while actually improving the wall system’s fire performance. And we did it without any additives that may be harmful to people or the environment. Plus, Formawall comes with a Health Product Declaration, offering the reassurance of full product and material transparency for your next project. DOWNLOAD THE HEALTH PRODUCT DECLARATION


CENTRIA surpassed the current required protocols for the NFPA 285 complete wall assembly test to simulate real-world applications of the Formawall system with features such as flashings or extrusions, variable striations, multiple reveal configurations, varying widths, vertical gaskets, and the Formawall insulated metal vertical (IMV) joint. This ensures that your next project is tried and tested – regardless of the panel application or design parameters. We even included non-CENTRIA products that may be incorporated within the wall assembly. Although not a requirement of Formawall, CENTRIA has also tested and approved 58 different weather-resistive barriers for use behind the wall system.


With its new enhanced fire-protection foam insulation, CENTRIA Formawall insulated metal wall panel system is UL-listed for both US and Canada (CAN/ULC-S134), North America’s seal of approval for safety.


With CENTRIA’s new foam core formulation, Formawall meets the most strigent requirements of FM4882 – the FM Global standard for smoke-sensitive environments.


The opportunity to enhance life safety shouldn’t come at a premium. That’s why CENTRIA Formawall now comes standard with enhanced fire protection.

Fire safety. It’s a top priority of architects, owners, and CENTRIA, and why we set out to make Formawall the world’s safest foam-insulated metal panel wall system.

CENTRIA Formawall with its new halogen-free insulating foam core easily passes the proposed updated NFPA 285 fire test.

More important, unlike other manufacturers’ panels, every Formawall panel passes the new standard – regardless of panel thickness, orientation, depth of reveal, finish, vertical joint type, or profile shape – with both steel tube and steel stud construction.

Equally impressive, every Formawall panel passes without the aid of fire-resistant interior gypsum.

For architects and owners, this means you can specify any Formawall product – for buildings of any height or application – and know that your decision is helping to enhance life safety.

About the Updated NFPA 285 Fire Test

As required by the International Building Code (IBC), the 30-minute NFPA 285 test predicts how an assembly will perform in a real-world multi-story application and, most critically, whether or not building occupants will have enough time to safely exit a building in a fire event.

Soon, NFPA 285 will be revised to make the test an even more accurate predictor of fire performance. The revised test will mandate the use of both horizontal and vertical wall panel joints (an area of higher fire vulnerability), and will specify the precise joint locations on the test specimen.

Know that CENTRIA has always gone above and beyond NFPA 285 requirements by including both horizontal and vertical joints.

NFPA 285 Pass/Fail Test Parameters

All three parameters must be met in order to pass.

  1. No flame propagation to the interior of the second story
  2. Flame may not reach 10’ above the top of the window opening or 5’ laterally from the window jamb in either direction
  3. Thermocouples located throughout the assembly must not exceed designated temperatures

NFPA 285 requires at least one vertical joint placed above the opening within 12" of the opening centerline, and at least one horizontal joint locapng within the first story between 1' and 3' above the window head.
