Structural Insulated Panels (SIPs)
Enercept has been manufacturing quality Structural Insulated Panels (SIPs) for over 30 years.
Enercept started as a subsidiary of Energy Concept in 1981. With the vision of crafting a future in manufacturing structural insulated panels, founder Harold Henley dared it all. By 1982, Enercept, Inc. built a 26,000 square-foot facility of their own design and products in Watertown, South Dakota.
Enercept designs custom Structural Insulated Panels (SIPs) to exactly fit your building needs. Whether you’re building a timber frame, conventional home, commercial, agricultural or light industrial structure, Enercept SIPs are the perfect fit for your project. Our SIPs are high-performance building panels made with an expanded polystyrene (EPS) rigid foam core sandwiched between two structural skins of 7/16″ oriented strand board (OSB) used in floors, walls, and roofs. Enercept’s standard 6″ SIP wall has an R-24.87 value, and we additionally offer R-40 or R-50 panels for your roof. Every panel is custom-manufactured to fit.
