Custom Structural Insulated Panels for Energy-Efficient Building
Founded in 1981 by visionary Harold Henley, Enercept has been at the forefront of structural insulated panel (SIP) manufacturing for over four decades. Our precision-crafted SIPs combine expanded polystyrene (EPS) foam cores with oriented strand board (OSB) skins to deliver energy-efficient, durable building solutions. Headquartered in Watertown, South Dakota, we serve residential, commercial, and agricultural sectors across North America. Our patented panel connector design eliminates thermal bridging, ensuring superior insulation performance. With factory-built accuracy, we reduce construction timelines by up to 60% while maintaining structural integrity. Our team of experts provides end-to-end support, from initial design to delivery, ensuring seamless project execution.Backed by membership in the Structural Insulated Panel Association (SIPA) and National Association of Home Builders (NAHB), we prioritize sustainability and innovation. Our Ready-To-Assembly (RTA) packages include pre-installed electrical chases, headers, and detailed construction guides. With testimonials from builders and homeowners highlighting our flexibility and quality, we remain committed to advancing energy-efficient construction methods. Our 26,000-square-foot facility, built entirely with our own SIPs, exemplifies our confidence in our products. Through continuous improvement and customer-centric service, we maintain our position as a trusted leader in high-performance building systems.

SIP Wall Panels
Enercept's SIP Wall Panels provide high-performance insulation with EPS foam cores between OSB skins. These pre-assembled panels reduce construction time, lower energy costs, and offer structural integrity. Ideal for residential and commercial buildings, they ensure airtight envelopes and minimal thermal bridging.
SIP Roof Panels
Our SIP Roof Panels feature continuous EPS insulation for superior thermal performance. Large-format panels install quickly, reducing labor costs while withstanding heavy snow and wind loads. The solid foam core maintains shape and minimizes heat loss over time.
Basement Panels
Enercept's basement SIPs include treated plywood exteriors and built-in studs for moisture resistance. Factory-cut openings and electrical chases streamline installation, creating energy-efficient lower levels that feel like main-floor spaces.
Commercial SIPs
Custom SIPs for commercial buildings deliver faster construction timelines and energy savings. Panels are engineered for large-scale projects with irregular designs, offering structural strength and compliance with commercial building codes.
Timber Frame SIPs
Our SIPs integrate seamlessly with timber frame designs, combining traditional aesthetics with modern efficiency. Panels provide insulation and structural support while maintaining the visual appeal of exposed timber elements.
Questions
What are Structural Insulated Panels (SIPs)?
SIPs are high-performance building panels with EPS foam cores and OSB skins. They provide structural framing, insulation, and air sealing in one component for faster, more energy-efficient construction.
How do Enercept SIPs improve energy efficiency?
The continuous EPS insulation eliminates thermal bridging, reducing heat loss by up to 60%. The airtight building envelope minimizes energy waste compared to traditional stick-framing methods.
Can SIPs be used for commercial projects?
Yes, Enercept offers custom SIP solutions for commercial buildings, including offices, agricultural facilities, and light industrial structures. Panels are engineered to meet commercial code requirements and project-specific loads.
What is the SIP project process?
The process includes submitting plans, receiving an estimate, making a down payment, approving layout drawings, finalizing payments, and production. Panels ship directly to the job site for quick installation.
Do you offer installation support?
Yes, we provide free virtual on-site assistance through phone or video conferencing. Our team helps troubleshoot challenges and ensures proper SIP installation for optimal performance.

Report
I was working with Enercept for wall panels for our home and originally they are at six week lead time and at a decent price. As the project continues they keep lifting price and extending lead times to where in a matter of a few weeks they just about double in price and extend product delivery date four months. (I know this is a crazy year but this is unacceptable to lead on customers like this) Be cautious when dealing with.
