Chicken wire roof and method of insulation

Claim 1

In a roof structure comprising a plurality of approximately equally spaced purlins oriented parallel to one another in a common plane, each of said purlins including an upwardly extending central web and oppositely laterally extending upper and lower flanges, the improvement therein of each of said purlins defining groups of openings through its central web, said groups of openings being spaced along the length of the purlins with the openings of each group being variably spaced from the flanges of the purlins and with the openings of the purlins being in approximate alignment with the openings of the purlins on opposite sides thereof, a plurality of support straps oriented parallel to one another and extending through the openings of the central webs of said purlins, elongated strips of wire mesh positioned between and extending parallel to said purlins and resting on said support straps and spanning the space between the central webs of adjacent ones of the purlins, elongated sheets of substantially impervious material positioned between and extending parallel to said purlins and resting on said sheets of wire mesh and spanning the space between the central webs of adjacent ones of the purlins, a layer of heat insulation material extending over each sheet of material, and sheets of roofing material mounted on said purlins.

Claim 9

A method of applying sheet material or the like to a roof structure of a building of the type including a plurality of purlins oriented in approximately parallel relationship with respect to one another, the steps of supporting reels of wire mesh and reels of sheet material over the spaces between adjacent pairs of purlins, unreeling the wire mesh and unreeling the sheet material into the spaces between adjacent ones of the purlins, progressively placing hard roofing material over the unreeled ends of the wire mesh and sheet material and on the purlins, and progressively moving the plurality of the reels along the lengths of the purlins ahead of the hard roofing material and unreeling the wire mesh and unreeling the sheet material into the spaces between adjacent ones of the purlins as the hard roofing material is placed over the unreeled ends of the wire mesh and sheet material.

Claim 10

A method of applying sheet material or the like to a roof structure of a building of the type including a plurality of purlins oriented in approximately parallel relationship with respect to one another, the steps of supporting reels of wire mesh and reels of sheet material over the spaces between adjacent pairs of purlins, unreeling the wire mesh and unreeling the sheet material into the spaces between adjacent ones of the purlins, progressively placing hard roofing material over the unreeled ends of the wire mesh and sheet material and on the purlins, and progressively moving the plurality of the reels along the lengths of the purlins ahead of the hard roofing material and unreeling the wire mesh and unreeling the sheet material into the spaces between adjacent ones of the purlins as the hard roofing material is placed over the unreeled ends of the wire mesh and sheet material.

Claim 12

A method of applying a roof to a building of the type including inclined parallel rafters and a plurality of purlins with upwardly extending central webs and oppositely extending upper and lower flanges mounted on and extending across the rafters comprising extending a wire mesh support between adjacent ones of the purlins at a level above the lower flanges of the purlins, placing elongated sheets of vapor impermeable material on the wire mesh support between the purlins with the lengths of the sheets extending parallel to the purlins, placing insulation material on the sheets, and applying hard roofing material to the purlins over the insulation material.

Claim 13

A method of applying a roof to a building of the type including inclined parallel rafters and a plurality of purlins with upwardly extending central webs and oppositely extending upper and lower flanges mounted on and extending across the rafters comprising extending a wire mesh support between adjacent ones of the purlins at a level above the lower flanges of the purlins, placing elongated sheets of vapor impermeable material on the wire mesh support between the purlins with the lengths of the sheets extending parallel to the purlins, placing insulation material on the sheets, and applying hard roofing material to the purlins over the insulation material.

Claim 16

A method of insulating a roof structure on a building of the type including a plurality of parallel purlins with upwardly extending central webs and oppositely extending upper and lower flanges comprising mounting a platform on the purlins, simultaneously moving the platform along the purlins and paying out layers of wire mesh and sheet material from the platform down between the upper flanges of the purlins into the spaces between the central webs of adjacent ones of the purlins, supporting the wire mesh from the purlins and supporting the sheet material on the wire mesh, placing insulation material on the sheets of material, and applying hard roofing material to the purlins.

Claim 17

A method of insulating a roof structure on a building of the type including a plurality of parallel purlins with upwardly extending central webs and oppositely extending upper and lower flanges comprising mounting a platform on the purlins, simultaneously moving the platform along the purlins and paying out layers of wire mesh and sheet material from the platform down between the upper flanges of the purlins into the spaces between the central webs of adjacent ones of the purlins, supporting the wire mesh from the purlins and supporting the sheet material on the wire mesh, placing insulation material on the sheets of material, and applying hard roofing material to the purlins.
