Introducing Polycore Building Systems by EcoFab Structures Inc. Combining the strength and durability of steel with the insulation value and physical properties of Expanded Polystyrene (EPS). Polycore provides a solution to common problems often experienced with traditional building material. Our custom designed and engineered panels can be installed faster and for less cost than cribbed or framed structural walls. Because Polycore does not rely on wood or concrete materials, it is not susceptible to mold or mildew, nor is it prone to fractures or cracking. Our EPS walls are super insulated so you can enjoy consistent temperatures throughout your home, year round, for vastly reduced energy costs as compared to conventional building methods.
