Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB).

SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design.

The result is a building system that is extremely strong, energy efficient and cost effective. Building with SIPs will save you time, money and labor.

Are SIPs More Expensive?

Building with SIPs generally costs about the same as building with wood frame construction when you factor in the labor savings resulting from shorter construction time and less jobsite waste. Other savings are realized because smaller heating and cooling systems are required with SIP construction.
