Yes, in cathedral ceilings and cathedralized attics, SPRAYTITE does not promote deterioration of the existing roof sheathing, because a properly designed spray foam application does not allow condensation between the foam / roof deck interface. Some traditional insulation systems have high air / vapor permeance and moisture retention, which could lead to water accumulation against the underside of the sheathing. SPRAYTITE insulation can be applied without roof ventilation, because it is fully adhered and air / vapor impermeable (at over 2″ thickness). See the 2006 International Codes for additional acceptance criteria for unvented roof designs.
