Apparatus for applying insulating material to a roof structure having a heat reflective layer

Abstract

A method and apparatus for installing insulation material within a roof structure (11). The apparatus includes a carriage (26) which is urged along the purlins (18) of the roof structure (11). A roll of insulation material (43) is mounted to the carriage (26) and dispenses a substantially continuous sheet of blanket insulation material (39) over the purlins (18) as the carriage (26) is progressively moved along the length of the purlins (18). A radiant barrier dispenser (70) dispenses a layer of radiant barrier material (72) over the dispensed blanket insulation material (39), and a cross-wise layer of insulation (86) is applied across the length of the purlins (18) in a direction normal to the direction of application of the blanket insulation material (39). Thereafter, sheets of hard metal roofing material (24) are attached to the purlins (18) over the cross insulation (86) to form the insulated roof structure (11).
