Not all construction is created equal. For many of our garages and ADUs we build with SIPs — Structural Insulated Panels — and it makes a real, lasting difference for the homeowner. Here’s why.
What a SIP actually is
A SIP is a sandwich: a thick core of rigid foam insulation bonded between two structural skins. The panel is the wall and the insulation in one — engineered, consistent, and free of the gaps and thermal bridges you get with stick framing.
What that buys you
- A tighter envelope — far fewer air leaks, so the building holds its temperature.
- Lower energy bills — continuous insulation means less heating and cooling, month after month.
- A stronger build — SIP structures are rigid and durable.
- A faster build — panels go up quickly, shortening the timeline on site.
- A quieter space — the solid core dampens sound.
SIP vs. stick framing
Traditional stick framing leaves cavities, seams, and studs that conduct heat. It works — but it leaks more and insulates less. For an ADU you’ll heat and cool for decades, the efficiency of a SIP build pays for itself in comfort and lower bills.
