High-Performance Building Panels
Build Smarter with Enercept High-Performance SIP Panels
At Enercept, we say Structural Insulated Panels (SIPs) are “the future of framing”—but that future is already here. Since 1981, Enercept has been manufacturing high-performance SIPs that are stronger, tighter, and more energy-efficient than traditional framing methods.
Known as “The Builders’ Choice,” we’ve earned our reputation by delivering customized, precision-engineered SIP systems backed by an experienced team and nationwide network of builders. Whether you’re building a home, commercial facility, or agricultural structure, Enercept SIPs are the smart, sustainable solution for modern construction.
Engineered for Strength, Speed, and Sustainability
Enercept SIPs combine structural framing, insulation, and sheathing into one high-performance panel. Each SIP is made with a rigid EPS foam core laminated between two OSB skins.
Our wall and roof panels offer:
Exceptional thermal resistance
Reduced air infiltration for a tighter building envelope
Energy savings of up to 60%
Faster construction with fewer labor hours
Compatibility with LEED® and ENERGY STAR® certifications
No chlorofluorocarbons (CFCs) or urea-formaldehyde (UF)
Enercept SIPs are ideal for walls, roofs, foundations, basements, and floors—delivering strength, simplicity, and long-term performance from the ground up.
Below-Grade Performance: Basement, Foundation, and Floor SIP Panels
Enercept Basement Panels
Enercept basement SIPs offer a warm, dry, and comfortable lower level—making your basement feel more like your main floor. Our pre-built system allows for faster installation and eliminates the need to fur out your walls.
0.60 retention treated plywood on the exterior, OSB on the interior
Factory-cut window openings and electrical chases
Built-in treated studs with bull-nosed connectors for a tight seal
Installed on CCA-treated bottom plates
Keeps basements airtight and energy-efficient year-round
Enercept Foundation Panels
For cold-climate performance and below-grade energy efficiency, Enercept's EPS-insulated foundation panel system protects plumbing and ensures minimal heat loss.
Requires less than 12% the thickness of a concrete wall to achieve the same thermal performance
Standard height: 4 feet
Green-treated plywood on both faces
Studs placed 16" on center
Delivers superior R-values and long-term durability
Enercept Floor Panels
Enercept floor panels are built like our roof panels—laid flat for strength and performance beneath your feet.
These SIP floors feature:
A solid EPS core with intermediate structural members
Custom fabrication for various spans and load requirements
High R-values and excellent thermal performance
Standard designs for residential loads, with upgraded specs available
Enercept floor panels help speed up construction and maintain thermal continuity between your building’s envelope and subfloor.
Airtight, Energy-Efficient, and Healthier by Design
According to the Structural Insulated Panel Association (SIPA), SIPs are one of the most airtight and well-insulated building systems available. That means:
Lower heating and cooling costs
Less strain on HVAC systems
Improved indoor air quality
Less energy waste and fewer CO2 emissions
Greater comfort in all seasons
With Enercept SIPs, you’re not just building better—you’re building for long-term health and sustainability.
