What Are SIPs?
The Smarter Way to Build
Structural Insulated Panels (SIPs) are transforming the way buildings are constructed — and Enercept is leading the way. If you're new to SIP construction or want to understand the basics, this page is for you.
At Enercept, we manufacture custom SIPs that combine framing, insulation, and sheathing into a single high-performance panel. Our SIP systems simplify construction, reduce energy costs, and provide unmatched strength and efficiency — making them the smart choice for residential, commercial, and agricultural builds.
Understanding SIPs: What Are Structural Insulated Panels?
SIPs are a composite building material made up of three key components:
A solid EPS (Expanded Polystyrene) insulation core
Two outer layers of 7/16” Oriented Strand Board (OSB)
Laminated together under factory-controlled conditions
These panels are used to construct walls, roofs, floors, and foundations, providing superior thermal performance and structural strength in one system.
SIPs vs. Traditional Framing: A Smarter Building Method
How do SIPs compare to traditional stick-framing? See for yourself:
| Feature | Enercept SIPs | Traditional Framing |
|---|---|---|
| Build Time | Fast (precut panels) | Slow (onsite cutting) |
| Labor Requirements | Reduced | High |
| Energy Efficiency | Up to R-50 | Varies by insulation |
| Air Tightness | Superior | Prone to leakage |
| Job Site Waste | Minimal | Significant |
| Structural Strength | High (laminated panels) | Moderate |
| Cost Over Time | Lower (energy savings) | Higher (operating costs) |
SIPs outperform stick framing in every major category — and Enercept makes it easy to get started.
How Are SIPs Installed?
Enercept SIPs are delivered to your site ready to install, with:
Pre-cut window and door openings
Factory-installed electrical chases
Easy-to-read layout drawings and guides
On-call virtual installation support for builders
SIPs reduce the margin for framing error and make it possible to enclose a structure in days rather than weeks — even in challenging weather or remote locations.
