SIS Panels

At SIS Panels, we’re redefining how buildings are built and renovated by replacing outdated, labor-heavy methods with a smarter, more efficient solution. Our Structural Insulated Sheathing (SIS) Panels combine structural sheathing and exterior insulation into a single, easy-to-install panel that meets and exceeds modern energy standards. Simply swap traditional sheathing for insulated sheathing to build for the future—without changing time-tested construction methods. Every project is unique, which is why customization is at the core of what we do. Choose the sheathing and insulation combination that works best for your build—whether it’s OSB with EPS, DensGlass with rigid mineral wool, Plywood with XPS, or anything in between. With proven performance in all types of construction, SIS Panels help more people build stronger, better-insulated, and more comfortable spaces—one panel at a time.
