High-Performance Building with Enercept (SIP) Panels

At Enercept we like to say that structural insulated panels (SIPS) are “the future of framing,” but in truth, the future is now. Enercept has been fabricating SIPS since 1981, and
has built a reputation for delivering the most customized SIPs on the market. That is why we are the “builders’ choice.” Earning industry respect and repeat business from builders does not happen by chance. It is developed over time by a conscientious team which brings their “A-game” each and every day. At Enercept, producing a quality product and quality customer service are always top of mind. Whether you are building a residential home, a commercial building or an agricultural structure, Enercept offers cost-efficiency, energy efficiency, improved air quality — and the latest in green building construction. The Enercept team and nationwide network of dealers and builders are ready to bring environmentally friendly, worry-free framing and insulation solutions to you.


Importance of Green Sustainable Building

Buildings impact both the environment and the people within them. Sustainable or “green” building design and construction is a method of wisely using resources to create high-quality, healthier and more energy-efficient homes and buildings. A focus on ensuring less energy and water use, better indoor air quality and a reduced impact of a building on the site it occupies are all elements of green building. While LEED® is identified with “going green,” green building has been a hallmark of Enercept’s building practices since 1981. Enercept helps its customers get Net-Zero-Ready with its high-performance products laying the green foundation for your next steps.

Enercept SIPs are high-performance building panels made with an expanded polystyrene (EPS) rigid foam core, sandwiched between two skins of 7/16” oriented strand board (OSB) used in floors, walls and roofs. SIPs save energy and reduce CO2 emissions—they are one of the most airtight and well
insulated building systems available, according to SIPA. A superior building envelope means high thermal resistance with minimal air filtration.

  • Our panels are made with oriented strand board (OSB) that is produced from fast-growing, less expensive trees grown on tree farms, promoting tree conservation.

  • Scrap foam and wood from our production cycle is ground and recycled

  • Less on-site waste means less stress on area landfills.

  • Energy savings of up to 60% compared to conventionally built stick structures of similar size.

  • Enercept structures are airtight, reducing the unwanted transmission of outside allergens and dust and creating a healthy home environment.

  • Our SIPs contain no chlorofluorocarbon (CFCs) or urea-formaldehyde (UF).

  • Structures made with our panels are compatible with Leadership in Energy & Environmental Design (LEED) certification and the ENERGY STAR rating.
