[Spray Foam Insulation] Performance typically exceeds published R-Values because laboratory tests of insulating power do not consider heat transfer due to air movement, which spray foam blocks.
Performance is typically less than published R-Values because laboratory tests of insulating power do not consider heat transfer due to air movement, settling and imperfect installation fit.
