The Ray-Core roof rocks! No icicles to date and the house has a history of some massive ones. Thanks again for the great new roof!

  • John Scott
  • Homeowner & VP Telematic Solutions

From day one my company has been about quality, the customer and how I could save them money. I have always been very interested in building a high energy efficient home. In each of my houses I try to figure out some special thing that will make my spec homes stand out and make them better than the competition. ... cutting heating and cooling bills by 40%... RayCore is a simple way to make my spec homes far superior!

  • Travis Staker
  • Builder - Idaho

The main reason our firm uses the (RAY-CORE) panels is their energy efficiency and insulation value. We want to give our homeowners a home that will not only be comfortable but energy efficient, thus lowering utility bills and saving the homeowner money over the long term. We figure on a 1,600 square foot home the cost to be less than $2000 to build with RAY-CORE SIPs. That can easily be made up in utility bill sin the first couple years of ownership.

  • Tanya Cromwell, President
  • Designer - Idaho Home Design

I can honestly say I enjoyed and benefited more from talking to you than anyone else in sales in recent memory. It is most obvious you enjoy your job; you fully understand your product; you put a sincere emphasis on helping your customer; and you fully understand what is pie in the sky and what is not. Thank You. As I said earlier, I keep a very short list of sources, and you surely have earned your spot in my list.

I think this is one of the best designs of pre-fabricated foam panels on the market because it is basically a code complying stud wall filled with foam!! Easy-peasy! This is a good wall for all you DIYers as well as contractors wanting to do a super insulated wall system that is a traditional code complying wall except it is pre-fabricated!

  • Dave Merinet
  • Building Code Official

The SIP panels are wonderful. As soon as they were on, before the ply and everything else, we could immediately notice much improved heat retention overnight. We expect the summers to be better as well. My wife and I appreciate your assistance and willingness to answer all our many questions.

  • Peter Lindquist
  • Colorado

It was my responsibility to seek out and develop state of the art products for the building industry. A range of structural insulated panels (SIP) were considered. The reasons for selecting RAY-CORE over sandwich-type SIPs were significant. What we learned: Carpenters quickly learned to use them and liked them. Walls went up fast with insulation and vapor barrier already in place. When the walls were framed they were immediately weather proof. Windows were easily installed. The experience was very positive in all respects.

  • Richard M. Fantazier, Ph.D.
  • General Manager (Retired), Armstrong World Industries, Inc.

I'm grateful that you were able to get the panels to me much earlier than originally stated, and I'm quite happy with the ease and quickness of using these panels.

  • Bill T.
  • Texas

After doing a lot of research with different companies for SIPs options for our home, we are extremely grateful to have learned about your company. 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, and we look forward to receiving your panels in a few weeks!
