    I love your insulated SIPs. The walls were slick and easy to put up. Everything came out square and plumb. I would love to use your product again.

    I think this is one of the best designs of pre-fabricated foam panels on the market...basically a code complying stud wall with foam!! Easy-peasy!

    Ken Auvil (VA)

    My total electric home has run about $200 a month for 38 years. If I had Ray-Core panels for those 456 months my bill would have been cut in half, thats a savings of $45,600.

    Reiner Hoyer (ON)

    When asked if he was pleased with the performance of his Ray-Core house - "Absolutely! Living in a house that cost me less than $20 a month to heat in the middle of the winter is a great thing!

    Travis Staker, Builder (ID)

    In each of my houses I try to figure out some little special thing that will make my spec homes standout and make them better. RAY-CORE is a simple way to make my spec homes far superior!

    You've done an excellent job helping us make the right decision. We are impressed with the R-value of your panels in comparison with others that were much thicker and more expensive. Thanks for your assistance.
