Air sealing a home, in addition to maximizing R-value, will further improve energy performance. When closed cell foam is installed between framing the thermally bridging framing SUBSTANTIALLY robs it of it's potential performance.

All three types of SPF can satisfy the R-value requirement for: walls, floors, ceilings, and roofs in every climate.

This is cross-matched to the area receiving the insulation.
