Can it be used for cathedral ceilings?
Yes. In cathedral ceiling applications, our foam system does not promote deterioration of the existing roof sheathing because it does not allow condensation at the foam/deck interface. Some traditional insulation systems have high water absorption and hold moisture against the underside of the sheathing. Our foam system can be applied without roof ventilation because it is fully adhered and air impermeable. Moisture does not condense between the insulation and the sheathing. Building code requirements for insulation ventilation requirements must be followed or discussed with the building professionals during the building insulation planning phase.
