Thermal insulation quilt

Abstract

A multi-layer, thermal insulation quilt (1) comprises two spaced apart, outer layers (2, 3) at least one of which is a reflective thermal insulation layer, between which outer layers there is provided at least one inner layer (4) of thermal insulation, characterised in that the outer layers (2, 3) secured together by a non-metallic, common restraining tag (5) of such length, that the tag (5) determines the maximum separation of the outer layers (2, 3) but effects no compressive loading on the or each thermal insulation layer (4).

1 . The use of a multi-layer, thermal insulation quilt as insulation in a wall or roof of a building, wherein the multi-layer, thermal insulation quilt comprises two spaced apart, outer layers at least one of which is a reflective thermal insulation layer, between which outer layers there is provided at least one inner layer of thermal insulation, wherein the outer layers are secured together by an array of non-metallic restraining tags of such having a length such that tags determine the maximum separation of the outer layers but effect no compressive loading on the or each thermal insulation layer. 
     
     
         2 . The use of a quilt as claimed in  claim 1 , wherein both outer layers are of reflective thermal insulation. 
     
     
         3 . The use of a quilt as claimed in  claim 1 , wherein the, or each, outer layer of reflective thermal insulation is a foil. 
     
     
         4 . (canceled) 
     
     
         5 . The use of a quilt as claimed in  claim 1 , wherein the, or each, outer layer of reflective thermal insulation is a foil selected from the group comprising an aluminium foil and a metallic polyester foil. 
     
     
         6 . The use of a quilt as claimed in  claim 5 , wherein the aluminium foil has an outer surface which is provided with a coating to prevent, or reduce, oxidation. 
     
     
         7 . The use of a quilt as claimed in  claim 6 , wherein the coating is of nitrocellulose. 
     
     
         8 . The use of a quilt as claimed in  claim 5 , wherein the, or each, outer, aluminium foil layer is reinforced by a grid of fiberglass fibres. 
     
     
         9 . The use of a quilt as claimed in  claim 1 , wherein the, or each, thermal insulation layer is compressible. 
     
     
         10 . The use of a quilt as claimed in  claim 1 , wherein the, or each, thermal insulation layer is fibrous. 
     
     
         11 . The use of a quilt as claimed in  claim 10 , wherein the quilt comprises multiple fibrous insulation layers, at least some of which are separated by at least one layer selected from the group comprising at least one metallised layer and at least one extruded polyethylene layer. 
     
     
         12 . The use of a quilt as claimed in  claim 10 , wherein the quilt comprises six fibrous insulation layers and five separating layers. 
     
     
         13 . (canceled) 
     
     
         14 . The use of a quilt as claimed in  claim 1 , wherein the tags are formed of a material, said material being one selected from the group comprising nylon and cotton. 
     
     
         15 . The use of a quilt as claimed in  claim 1 , wherein the tags are of monofilament nylon. 
     
     
         16 . (canceled) 
     
     
         17 . The use of a quilt as claimed  claim 1 , wherein each tag comprises an abutment, an enlargement, or a head at each end adapted to engage the external surface of the adjacent outer layer. 
     
     
         18 . The use of a quilt as claimed in  claim 17 , wherein the abutment, enlargement, or head is an orthogonal bar of T-like form. 
     
     
         19 . The use of a quilt as claimed in  claim 17 , wherein the abutment, enlargement, or head, at least at one end of the tag, is circular to provide an enlarged abutment surface. 
     
     
         20 . The use of a quilt as claimed in  claim 1 , wherein the tags are of a contrasting colour compared with the outer layers, such that the location of each tag is readily identifiable should it be required to release or remove the tags. 
     
     
         21 . (canceled) 
     
     
         22 . The use of a quilt as claimed in  claim 1 , wherein the tags are installed at suitable longitudinal and transverse spacing such that when the quilt is cut to size or fit, a sufficient number of tags remain in place to maintain the integrity of the quilt along suitable connection lines whether straight or zig-zag. 
     
     
         23 . The use of a quilt as claimed in  claim 22 , wherein the connection lines are at least adjacent peripheral edges of the quilt. 
     
     
         24 . The use of a quilt as claimed in  claim 1 , comprising 15 layers, being:
 1. foil insulation having a shiny side facing out;   2. polyester wadding;   3. metallised polyester;   4. extruded polyethylene;   5. extruded polyethylene;   6. metallised polyester;   7. polyester wadding;   8. metallised polyester;   9. polyester wadding;   10. metallised polyester;   11. extruded polyethylene;   12. extruded polyethylene;   13. metallised polyester;   14. polyester wadding;   15. foil insulation having a shiny side facing out.
