ABSTRACT:
An apparatus for providing a roof structure of the type has a plurality of purlins spaced apart from one another in a parallel arrangement. The space between the vertical portions of adjacent purlins defines an insulation cavity which is generally rectangular in cross-sectional shape. The apparatus includes a carriage movable in a first direction along the length of the purlins for paying out a support sheet for support of insulation material as the carriage travels along the length of the purlins. The apparatus also includes a platform attached to the carriage and extending in the direction opposite the first direction and placed in the insulation cavity. The platform is mounted on the carriage by two pairs of hinges for vertical movement.
