Develop specific detailing for insulating the overhang area.

What kind of insulation do you use for a cantilever overhang?

Fill in any gaps along the outside edges of the rigid insulation with expansion foam for an air-tight installation. Fill the rigid foam-lined cantilever cavity with batt insulation. Make sure the insulation does not flow below the opening of the cantilever cavity, or closing will be an issue.

What kind of insulation is used for overhanging floors?
