Enercept, Inc.

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 was incorporated and built a huge, 26,000 sq. ft. facility of its own design and products in Watertown, SD. Enercept has been manufacturing SIPs since 1981. Enercept designs custom Structural Insulated Panels (SIPs) to exactly fit your timber frame. Whether you're building a full timber frame or a hybrid (partial timber frame), enclosing timber frames with SIPs is 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. Enercepts standard 6" SIP wall has an R-24.87 value and we additionally offer R-40 or R-50 panels for your roof. Each and every panel is custom manufactured to fit on your timber frame. Each panel comes with our standard features including: Enercept installs electrical chases at the factory and has developed an easy to follow electrical guide for your electrician. Enercept factory-installs electrical wiring in our SIP roof panels (when allowed by local code). Not only have we been in business for over 30 years, we were also the original holders of the patents for our insulated connecting posts, which virtually eliminate thermal bridging, Our patented design means faster, easier, stronger construction. Enercept panels have been used internationally with projects in Antarctica, Spain, Japan, Switzerland, France, Mexico and Canada. The largest project being the recently completed International Science Station located at the South Pole. Enercept is a proud member of The Structural Insulated Panel Association (SIPA), the National Association of Home Builders (NAHB) and the Timber Framers Guild
