When builders across the globe need to design rooms with superior temperature control and resistance to fire or cold, they turn to Structural Panels Inc. For over 30 years, we have specialized in state-of-the-art prefab interior wall panels. As a family-owned business, we take genuine pride in our products and services, and continually seek to better meet the needs of modern contractors and the demands of their clients.

Our products provide superior heat and cold control with an R-value of 4.1 per square inch that doesn’t degrade over time. They’re affordable, CFIA-accepted, easy to install and simple to clean. Our two main product lines are:

Rockwall™

Rockwall™ prefab interior wall panels are designed to be fire-resistant with a Rockwool mineral fiber core which can be 2.5” to 10” in thickness. Bonded to either surface of the core are two prepainted G90 galvanized steel sheets that provide strength and durability even after years of use. When installed according to Warnock Hersey/Intertek specifications, 6” thick Rockwall™ provides 3 hours of passive fire-resistance.

Isowall®

Isowall® prefab interior wall panels are designed with temperature and climate control in mind. These are constructed from an Expanded PolyStyrene (EPS) foam core, with thicknesses ranging from 2″ to 10″ with pre-painted G90 galvanized steel on both sides. Isowall® is also mold/mildew and pest resistant, and the panel core resists the moisture and condensation that often forms in a cooler or freezer. Isowall® is easy to install and you can even transition seamlessly from Rockwall™ to Isowall® to help control costs between integrated environments.
