Cathedralized attic | Article about Cathedralized attic by The Free Dictionary
An unvented attic with insulation installed between the rafters or above the roof sheathing. Moving the insulation from the attic floor to the roof plane turns the attic into conditioned or semiconditioned space; this is especially beneficial in homes with attic ductwork. Usually refers to an attic that does not include finished space.
