What are SIPs?
Maybe you’ve heard about SIPs: Structural Insulated Panels. A complete building system that combines framing, sheathing, and insulation into one engineered component. Instead of assembling walls stick by stick, you’re installing factory-precision panels that deliver consistent performance every time. The result is superior strength, thermal efficiency, and construction speed that traditional methods simply can’t match.

Nantucket SIPs: Built for Energy Efficiency
Why build your home with SIPs?
What exactly are SIPs?
Structural Insulated Panels combine framing, sheathing, and insulation into one high-performance component.
Are SIPs really stronger than stick frame?
Factory-engineered panels distribute loads across the entire structure. Testing shows superior performance against wind, seismic, and snow loads.
How do SIPs handle electrical and plumbing?
Electrical chases are pre-routed during manufacturing. Plumbing runs through interior walls, eliminating freeze risk in exterior applications.
