Insulation system for metal buildings and the like
First Claim
1. An insulated roof comprising spaced and substantially parallel purlins each having an upper flange and a web extending substantially perpendicular thereto, roof panels supported by and secured to said flanges, and support means supported by said flanges and providing a shelf along each side of said web at a location spaced from said flanges, a plurality of struts at intervals along said shelves supported at their ends on opposed shelves, and elongated insulation blankets positioned between said purlins supported along their edges by said shelves and at intervals along their length by said struts, said support means including hangers at spaced locations along the length of said shelves, said hangers providing support portions positioned over said flanges.

Abstract
A method and apparatus is disclosed for installing insulation in metal buildings and the like. The apparatus includes a grid supported from the upper flanges of the purlins of the metal building and providing struts and shelves to support an insulation blanket below the upper flanges of the purlins. The shelves support the blanket along its edges and the struts support the blanket at intervals along its length. In accordance with the method, the grids are assembled and then pushed out along the purlins and are dropped down between the purlins while being supported from the upper flanges thereof. With such method, it is not necessary for workmen to work out along the purlins and the grids can be installed while the workmen stand on an end platform on panels of a partially completed roof.

- 1. An insulated roof comprising spaced and substantially parallel purlins each having an upper flange and a web extending substantially perpendicular thereto, roof panels supported by and secured to said flanges, and support means supported by said flanges and providing a shelf along each side of said web at a location spaced from said flanges, a plurality of struts at intervals along said shelves supported at their ends on opposed shelves, and elongated insulation blankets positioned between said purlins supported along their edges by said shelves and at intervals along their length by said struts, said support means including hangers at spaced locations along the length of said shelves, said hangers providing support portions positioned over said flanges.
- 6. An insulated roof system comprising spaced and substantially parallel purlins each having an upper flange and a web extending substantially perpendicular thereto, an elongated grid providing opposed shelves extending lengthwise thereof and a plurality of lateral struts connected at their ends to said opposed shelves in a substantially regular pattern providing openings, separate hanger means supporting each of said shelves providing vertically extending portions and horizontally extending portions overlying said flanges and supporting the associated shelves at a predetermined distance below said flanges, non-rigid, elongated insulation blankets extending lengthwise of said purlins supported along their length at their edges by said shelves and at lateral intervals along their length by said struts, said openings being sufficiently small so that said blankets do not sag excessively between said shelves and said struts, the connections between said struts and said shelves providing said grid with sufficient rigidity so that the grid may be supported at one end by said flanges and at its other end above said flanges for movement out along said purlins to an installed position, said horizontally extending portions at said one end being curved to facilitate sliding movement of said one end along said purlins.
- 12. An insulation support system for roofs having parallel purlins which support roof panels, comprising a pair of supports providing a pair of opposed shelves, a plurality of struts arranged in an X-shaped array and secured at their ends to said shelves and cooperating therewith to provide a stable insulation support grid, each of said supports providing a support projection adapted to overlay the upper surface of an associated purlin and support said shelf from said upper surface at a location below said upper surface, said support system being installable between a pair of purlins by resting one end on said upper surface and sliding it out along said purlins to an installed position.
- 14. An insulated roof comprising spaced and substantially parallel purlins each having an upper flange and a web extending substantially perpendicular thereto from one edge of said flange, an elongated grid providing opposed shelves extending lengthwise thereof and a plurality of lateral struts connected at their ends to said opposed shelves in a substantially regular pattern providing a plurality of openings spaced along said grid, separate hanger means supporting each shelf providing vertically extending portions and horizontally extending portions overlying said flanges and supporting the associated shelf at a predetermined distance below the associated of said flanges, non-rigid, elongated insulation blankets extending lengthwise of said purlins supported along their entire length at their edges by said shelves and at lateral intervals along their length by said struts, said openings being sufficiently small so that said blankets do not sag excessively between said shelves and said struts, said vertically extending portions being shaped to position said shelves substantially adjacent to the adjacent of said webs with one of said shelves extending under the associated of said flanges, said blankets along said one of said shelves extending under the adjacent flange and substantially to the adjacent web, and roofing secured to said flanges over said insulation.
- 18. A method of installing insulation on metal buildings having spaced parallel purlins comprising assembling an insulation support grid having support portions positioned to overlay the top of an adjacent purlin and support said grid at a location spaced below said top, sliding said support grid out along said purlins to an installed position, placing insulation on said support grid between said purlins, and mounting roof panels on said purlins over said insulation.
