Presentation Summary:
The more venting the better, right? Do unvented roofs work? Is spray foam the solution? Increased levels of thermal performance are becoming necessary as part of ever increasing energy requirements, but it is important not to lose sight of other key roof performance characteristics including durability and constructability. This presentation will address methods for achieving required levels of thermal performance for compact (non-attic) wood-frame roofs, and present results from field monitoring of in-service performance to highlight key performance considerations. Additionally, the recently new Illustrated Guide to R30+ Effective Roofs will be introduced.
