Structural Insulated Panels, Engineered for the Way You Build

Murus manufactures structural insulated panels (SIPs) — high-performance wall, roof, and floor panels that combine an insulating foam core between two structural OSB facings. Since 1987, builders, architects, engineers, and homeowners have used Murus SIPs to build stronger, tighter, more energy-efficient homes and commercial buildings up to 55% faster than stick framing.

One manufacturer. Three panel cores. The right fit for every project.

Most SIP companies make you build around one foam core. Murus makes all three — so the panel fits your performance target and your budget, not the other way around. You can compare EPS, GPS, and PUR SIPs side by side to find the right fit.

Polyurethane (PUR)

Our highest R-value per inch, for thin walls and demanding climates.

Graphite (GPS)

Graphite-enhanced foam: more R-value than standard EPS, less cost than PUR.

Expanded Polystyrene (EPS)

The proven, cost-effective workhorse core.

Why builders and owners choose SIPs

  • Build faster — weather-tight enclosures up to 55% sooner, cutting labor cost and schedule.
  • Spend less to heat and cool — SIP buildings typically lower HVAC costs 40–60% thanks to minimal thermal bridging.
  • Live more comfortably — fewer drafts, quieter rooms, better air quality.
  • Build greener — a straightforward path to LEED and NGBS certification.
