Colorado-based Ec Manufacturing started making structural insulated panels (SIPs) about a year and a half ago. The company was studying 2009 building code and thinking about how to innovate their products, when someone decided the building industry could use a thermally broken lumber material. That led to the creation of rSTUD.
rSTUD is made with laminated veneer lumber and a polyurethane foam bound by a patent-pending structure pack process. The company says the insulated lumber has an R-value of 21.
Ec Manufacturing is testing the new product and in talks with companies about manufacturing and distributing. Pricing is expected to be about $0.87 per linear foot and should become available in the first quarter next year.
With Passive House and what seems to be a growing interest in insulated, airtight structures, I thought it would be great to hear from readers on the potential advantages and disadvantages, if any, to a product like rSTUD. Open up below, if you have a thought.
