Structural Insulated Panels have exceptional strength to resist typical loads caused by seismic activity and high winds.  Six homes which used SIP components withstood the 7.2-magnitude earthquake in Kobe, Japan in January 1995. These homes were located just miles from the quake's epicenter and stood solidly against the tremendous force of the earthquake. All the SIP Structures were standing  after this great earthquake and almost all Non-SIP structures had crumbled to the ground. SIPs have been proven to withstand seismic activity in earthquake regions and high winds in hurricanes and tornadoes better than any stick-frame, timber-frame, or masonry structures. SIPs are energy efficient.

SIPs are a structural composite; three components work together. This composite assembly yields stiffness, strength and predictable responses. These three fused components provide a monolithic "sandwich", which is stronger than the individual components.  Not only do test results show panels are stronger, but real life natural disasters around the world have proven this fact many times.

SIPs have 3 times the strength of conventional dimensional lumber construction. SIPs have excellent compression, tensile adhesion, shear, and flex-strength.  This ensures superior capability to support axial loads in wall applications, high resistance to lateral loads caused by earthquakes or high winds, which increases the overall strength of the house. SIPs also make a home more durable by greatly eliminating settling effects.

Skip Lee is the only building inspector in Pamlico County, which borders North Carolina’s Pamlico Sound.  “I’m really impressed with the structural foam panels,” said Lee. “If I had my way, every home would be built with SIPs.  I like their low energy requirements for heating and cooling, they require less wood during construction, and they have great wind-load capability. In fact, the loading capability of the panels exceeds code requirements. Based on good design application, I have no problems with them structurally. I would not hesitate to use them in any home I might build for myself.”
