This project will study an innovative approach to roof insulation retrofits in which nailbase insulated panels are installed over the roof deck before re-roofing. These panels can be installed in one step and result in semi-conditioned attics. This project will demonstrate a value-added roof/attic retrofit solution for a range of older homes where traditional attic insulation approaches are not effective or feasible.

This is one of three Home Innovation Research Labs projects focused on advancing solutions for moisture-managed, high-performance envelope systems in three climate zones: hot/humid, mixed humid, and cold.


By improving the way that high-performance building envelope systems function in climates that are widespread across the United States, this project will help produce future homes that are more comfortable at a lower cost. Installing these roof insulation panels can reduce HVAC energy use by at least 10%. The project will also evaluate strategies for integration with routine re-roofing activities to minimize disruption to residents and reduce the cost of energy upgrades.
