Timothy Merrigan, M. Hoeschele, D. Springer, B. Dakin, A. German

Research output: NRELFact Sheet


High Performance walls represent a high priority measure for moving the next generation of new homes to the Zero Net Energy performance level. The primary goal in improving wall thermal performance revolves around increasing the wall framing from 2x4 to 2x6, adding more cavity and exterior rigid insulation and achieving insulation installation criteria meeting ENERGY STAR's thermal bypass checklist.
