Industrial building roofing system - with insulation paid out from reels and supported by strap lattice mounted in openings of purlins

摘要

A roof structure is fabricated by supporting a lattice of support straps through openings in the purlins and supporting one or more reels of insulation material on adjacent pairs of purlins with the width of the material spanning the space between the purlins. The reels are moved along the lengths of the purlins and the insulation material from the reels is payed out down into the spaces between the purlins and onto the lattice of support straps to substantially fill the space above the straps to the tops of the purlins. Additional insulation material is applied to the upper surfaces of the purlins. The workmen follow the reels of insulation material and connect the hard roofing material over the insulation material to the purlins to complete the roof structure.
