1/28/15 - Randy is a BIG fan of structural insulated panels (SIPs). SIPs are expanded polystyrene insulation sandwiched between two sheets of OSB (oriented strand board). They are fabricated in the shop according to the design of the house and then shipped to the construction site. We are fortunate to have a supplier of SIPs (Big Sky Insulation) with whom we have worked a lot located a little over two hours from Billings. Jim is our “go-to guy.” He is very patient when Randy calls him up and says, “Jim, I’ve got an idea!” Randy didn’t want thermal breaks anywhere in the house and he had a design idea how to accomplish that. Also, Randy wanted to avoid any grade stamp markings on the interior of the OSB panels which would require extra effort on the part of our supplier during fabrication. And, could we purchase additional FSC OSB through their shop instead of trying to find a supplier “from who knows where?” Jim made it happen and the SIPs started arriving on January 28, 2015. Thank you, Jim!
