Abstract:
1. A process of insulating and ventilating a building roof supported on rafters, comprising: Providing a rigid insulation panel having an upwardly facing major surface, an opposing downwardly facing major surface, and opposite edge surfaces extending between the major surfaces, spanning between two rafters or trusses, the rigid insulation panel having at least two separate brackets, each of the two separate brackets attached to the rigid insulation panel at a different opposite edge surface of the rigid insulation panel, each bracket having an upwardly projecting portion extending from an edge surface of the rigid insulation panel above the upwardly facing major surface of the rigid insulation panel for spacing the rigid insulation panel from the bottom of a roof by a predetermined distance to achieve an air ventilation channel, and a downwardly projecting portion that extends sufficiently downwardly from the edge surface of the rigid insulation panel below the downwardly facing major surface of the rigid insulation panel to allow fastening of the bracket to rafters supporting a building roof; the bracket also has two spaced apart horizontal arms one top and one bottom gripping the rigid insulation panel holding it in place; Positioning the rigid insulation panel with the attached brackets between rafters of a building so that the upper edges of the upwardly projecting portion of each of the brackets abut the bottom of an existing roof, whereby the rigid insulation panel is spaced from the roof by a predetermined distance to provide an air ventilation channel between the roof and the rigid insulation panel; and thereafter fastening the downwardly projecting portion of each of the brackets to the rafters, the rigid insulation panel being sufficiently rigid to maintain its shape while being supported between the rafters by the brackets attached at the edge surfaces of the rigid insulation panel.
