High-R Walls for New Construction Structural Performance: Integrated Rim Header Testing

Stacey Rothgeb, Stacey Rothgeb (NREL Technical Monitor)

Research output: NRELSubcontract Report


Two prominent approaches within the Building America Program to construct higher R-value walls have included use of larger dimension framing and exterior rigid foam insulation. These approaches have been met with some success; however for many production builders, where the cost of changing framing systems is expensive, the changes have been slow to be realized. In addition, recent building codechanges have raised some performance issues for exterior sheathing and raised heel trusses, for example, that indicates a need for continued performance testing for wall systems.
