Abstract
An insulated material comprises a first wall having a surface with a layer of insulation thereover. The insulation is anchored to the wall by a plurality of rods which are each attached to the wall and extends through the insulation. The rods are interlocked at expansion point means which allows expansion and contraction of the rods without permitting movement of the insulation from its position.
Claims6
An insulated material comprising a first wall having a surface with a layer of insulation thereover,
- said insulation being anchored to said wall by a plurality of rods each attached to said wall and extending through said insulation,
- said insulation being in sheet form and having a thermal conductivity in the range of from 0.01 BTU/hr/ft.sup.2 /.degree. F/ft to 0.2 BTU/hr/ft.sup.2 /.degree. F/ft.,
- said rods extend upwardly from said metal surface and being bent over to define a portion substantially coextensive with said wall sandwiching therebetween an insulating layer,
- a free end of each rod looped about and under a bent over portion of another rod so as to provide a sliding joint allowing expansion and contraction of each rod with respect to the joint while still maintaining said joint and binding said insulation to said plate,
- said rods are arranged in rows and adjacent rods are stitched to each other at said sliding joints, to form transverse rows,
- and transverse wire means interlocking with said sliding joints and mounted in slipping relationship therewith.
3 more elements
A method of insulating a metal wall comprising,
- welding upstanding rods to said wall in a grid pattern,
- providing a sheet insulation over said wall with said rods passing through said sheet and said sheet having a thermal conductivity in the range of from 0.01 BTU/hr/ft.sup.2 /.degree. F/ft to 0.2 BTU/hr/ft.sup.2 /.degree. F/ft,
- bending over rods successively on a surface of said sheet and looping each successive end about an intermediate portion of an adjacent rod and under a bent over portion thereof to form a sliding joint at each loop when said rods are axially expanded or contracted.
