When it comes to designing energy-efficient, high-performance building envelopes, simplicity matters. With Structural Insulated Panels (SIPs), meeting the 2024 International Energy Conservation Code (IECC) is straightforward—and smart.
By combining structure and continuous insulation (Ci) into a single precision-engineered panel, SIPs eliminate complex detailing and thermal bridging. A 6.5-inch SIP wall paired with a 10.25-inch SIP roof satisfies or surpasses insulation requirements for every U.S. climate zone. No layering, no guesswork—just a clean, code-compliant solution.
One Wall, One Roof, All Climate Zones
Designing for energy code compliance often means juggling R-values, multiple insulation layers, and climate-specific wall assemblies. But with SIPs, the path to high performance is refreshingly simple:
A 6.5-inch SIP wall meets or exceeds residential energy code requirements in every U.S. climate zone—even the coldest regions.
A 10.25-inch SIP roof clears the new 2024 IECC requirements, including higher R-values in northern zones.
And while some zones—like Florida or Southern California—technically allow thinner panels (such as 4.5" walls or 8.25" roofs), standardizing on a 6.5" wall and 10.25" roof provides total code coverage with no need for added Ci layers. That’s simplicity in action: one wall, one roof, any climate.
Simplify Energy Code Compliance with SIPs
SIPs make IECC 2024 compliance easier thanks to their built-in CI and airtight construction. SIPA’s Design Best Practices: High-Performance SIP Building Envelope guide outlines how SIP assemblies eliminate the need for layered insulation systems and tedious calculations.
Whether designing for extreme cold in the Rockies or intense heat in the Southwest, SIPs offer a consistent, code-compliant wall and roof solution that removes complexity from high-performance design. No extra insulation. No thermal bridging. Just straightforward energy efficiency.
Powerful in Performance, Simple for Design,
The updated IECC 2024 minimum insulation tables—featured in SIPA’s Design Best Practices guide—clearly show how SIPs deliver above-code R-values across climate zones.
Whether in Climate Zone 7 or Zone 2, a single SIP wall and roof configuration performs above the minimum thresholds for residential buildings.
Because SIPs integrate structure and insulation, they reduce material waste and on-site labor. Fewer trades. Fewer steps. Fewer chances for error. More confidence in your building envelope’s performance.
Smarter, Not Harder
SIPs don’t just simplify energy code compliance—they support healthier and more livable environments. Airtight construction enhances indoor air quality, limits drafts, and reduces energy demand. This translates into lower operational costs and higher occupant comfort—all while supporting sustainability targets.
Simplify Your Process—Without Sacrificing Performance
SIPs deliver structural integrity, thermal performance, and faster construction timelines—all with one panel size for walls and roofs. It’s rare to find a product that balances performance with simplicity, but SIPs check all the boxes.
