Retrofitting Rooftops: The Overcoat Method

NORTHERNSTAR BUILDING AMERICA Partnership has been investigating the use of an external insulation retrofit approach for existing houses under the “Project Overcoat” label. The overall design intent is to put thermal, air and moisture control layers over the exterior of an existing building, including the foundation, wall and rooftops. The approach uses a peel-and-stick membrane for an air barrier and layers of rigid foam for a thermal barrier to provide exceptional thermal and air barrier alignment and continuity in older homes with simple geometries. NorthernSTAR found the approach worked well for roof retrofits in 1-1/2-story homes, which are difficult to insulate under the roof due to lack of space, and often have serious air leakage problems that can lead to ice dams.

Result: Ecosystems are poisoned from the bottom up.
