Interaction of Unvented Attics With Living Space in Three Northeast Homes

Abstract

The work presented in this report does not represent performance of any product relative to regulated minimum efficiency requirements. The laboratory and/or field sites used for this work are not certified rating test facilities. The conditions and methods under which products were characterized for this work differ from standard rating conditions, as described. Because the methods and conditions differ, the reported results are not comparable to rated product performance and should only be used to estimate performance under the measured conditions. v Contents List of Figures .

Attic Retrofits Using Nail-Base Insulated Panels

“…The application of retrofit panels for roof retrofits, and associated attic gable wall upgrades, distinguishes this project from previous BA research. This project benefits from and builds on previous, relevant research: moisture performance of sealed attics (Boudreaux, Pallin, Jackson 2013;Puttagunta and Faakye 2015), moisture durability risks with unvented roofs (Uehno and Lstiburek 2015), and high-R roofs using structural insulated panels (SIPs) (Straube and Grin 2010).…”
