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 . A multi-layer, thermal insulation quilt comprising 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 secured together by an array of non-metallic restraining tags of such length, and in that the tags determines the maximum separation of the outer layers but effect no compressive loading on the or each thermal insulation layer. 
   
   
       2 . A quilt as claimed in  claim 1 , wherein both outer layers are of reflective thermal insulation. 
   
   
       3 . A quilt as claimed in  claim 1 , wherein the, or each, outer layer of reflective thermal insulation is a foil. 
   
   
       4 . (canceled) 
   
   
       5 . 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 . 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 . A quilt as claimed in  claim 6 , wherein the coating is of nitrocellulose. 
   
   
       8 . A quilt as claimed in  claim 5 , wherein the, or each, outer, aluminium foil layer is reinforced by a grid of fibreglass fibres. 
   
   
       9 . A quilt as claimed in  claim 1 , wherein the, or each, thermal insulation layer is compressible. 
   
   
       10 . A quilt as claimed in  claim 1 , wherein the, or each, thermal insulation layer is fibrous. 
   
   
       11 . 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 . A quilt as claimed in  claim 10 , wherein the quilt comprises six fibrous insulation layers and five separating layers. 
   
   
       13 . A quilt as claimed in  claim 12 , wherein the separating layers, being enclosed within the quilt, are of a non-reinforced kind. 
   
   
       14 . 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 . A quilt as claimed in  claim 1 , wherein the tags are of monofilament nylon. 
   
   
       16 . (canceled) 
   
   
       17 . A quilt as claimed in  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 . A quilt as claimed in  claim 17 , wherein the abutment etc is an orthogonal bar of T-like form. 
   
   
       19 . A quilt as claimed in  claim 17 , wherein the abutment etc, at least at one end of the tag, is circular etc to provide an enlarged abutment surface. 
   
   
       20 . 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 e.g. by cutting the tag with scissors after installation, to permit expansion or bagging of the quilt. 
   
   
       21 . (canceled) 
   
   
       22 . 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 . A quilt as claimed in  claim 22 , wherein the connection lines are at least adjacent peripheral edges of the quilt. 
   
   
       24 . 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.
