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).

Dependent claims

A method of insulating a roof structure of an industrial building of the type including a series of parallel approximately equally spaced purlins comprising the steps of:

mounting roll-support stands on said purlins with reels of heat insulation sheets supported on the roll-support stands;
intermittently moving the roll-support stands along the purlins;
in response to moving the roll-support stands along the purlins paying out the heat-insulation sheets from the reels and placing the heat insulation sheets from the reels in between the purlins with the edges of the heat insulation sheets in engagement with the purlins;
placing elongated heat-insulation sheets on top of and extending across the purlins to form a substantially uninterrupted upper layer of heat insulation material over the purlins;
and
placing heat reflective sheets on the heat-insulation sheets paid out from the reels to form a heat reflective barrier beneath the upper layer of heat insulation material extending longitudinally between the purlins.
