Rockwall™

Rockwall™ sandwich panels are designed specifically for fire-resistance and environmental control with an R-value of 4.1 per square inch that doesn’t degrade over time. Our CFIA-accepted Rockwall™ panels are manufactured from a Rockwool mineral fiber core with a pre-painted G90 galvanized sheet steel bonded to either side. When installed according to listing specifications, our fire-rated metal wall panels can provide 1, 2 or 3 hours of Warnock Hersey/Intertek-certified passive fire resistance. Better yet, they look great and can be manufactured to any maneuverable length/height you need.
