Yes. ThermaFoam R-Control SIPs have exceptional strength to resist seismic activity and high winds. R-Control has documentation of homes which used R-Control SIP’s that 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. R-Control SIP structures have also withstood tornados in Tennessee and straight line winds and tree trunks crashing into them in Michigan.
