Wall Insulation Panel

Abstract

A wall insulation panel for use on a wall comprises at least the successive layers of: a first protective panel having a wall-meeting surface and a vacuum insulating panel (VIP) facing surface, an intermediate VIP panel; and a second protective panel having a VIP facing surface and an outward facing surface. There is an expansion region between at least one of the first and second protective panels and the VIP panel to allow for expansion of the VIP panel without deformation of the outward facing surface of the second protective panel. In this way, the expansion region allows for expansion of the VIP panel without deformation of the VIP facing surface of the second panel, and thus without deformation of the outward facing surface. This maintains the integrity and aesthetic appearance of the outward facing surface, and any further surface or layer thereon, such as a rendered layer.

1 . A wall insulation panel for use on a wall comprising at least the successive layers of:
 a first protective panel having a wall-meeting surface and a vacuum insulating panel (VIP) facing surface,   an intermediate VIP panel; and   a second protective panel having a VIP facing surface and an outward facing surface;   wherein there is an expansion region between at least one of the first and second protective panels and the VIP panel to allow for expansion of the VIP panel without deformation of the outward facing surface of the second protective panel.   
     
     
         2 . The wall insulation panel as claimed in  claim 1 , wherein the expansion region includes a compensation layer. 
     
     
         3 . The wall insulation panel as claimed in  claim 2 , wherein the compensation layer includes one or more solid or semi-solid materials, at least a portion of which is deformable to accommodate expansion of the VIP panel. 
     
     
         4 . The wall insulation panel as claimed in  claim 3 , wherein the expansion region includes one or more of the group comprising: ribs, tubes, springs, low density soft foam, adhered ribs or tubes, extruded ribs or tubes, silicone foams. 
     
     
         5 . The wall insulation panel as claimed in  claim 4 , wherein the expansion region comprises a series of ribs or tubes extending between a VIP facing surface and the VIP panel, at least a portion of which ribs or tubes are deformable. 
     
     
         6 . The wall insulation panel as claimed in  claim 5 , wherein the ribs or tubes provide a corrugated surface between the VIP facing surface and the VIP panel. 
     
     
         7 . The wall insulation panel as claimed in  claim 5 , wherein the ribs or tubes extend wholly or substantially from the VIP facing surface to meet the VIP panel. 
     
     
         8 . The wall insulation panel as claimed in  claim 1 , wherein the expansion region is between the VIP facing surface of the second panel and the VIP panel. 
     
     
         9 . The wall insulation panel as claimed in  claim 1 , wherein the VIP panel extends to two opposing sides of the wall insulation panel. 
     
     
         10 . The wall insulation panel as claimed in  claim 1 , wherein the outward facing surface of the second protective panel has a rendered finish thereon. 
     
     
         11 . The wall insulation panel as claimed in  claim 1 , wherein the VIP panel is a fumed silica VIP panel. 
     
     
         12 . The wall insulation panel as claimed in  claim 1 , wherein the second panel includes a transverse warning line parallel to the outward facing surface to indicate a cutting zone. 
     
     
         13 . A wall insulation cladding comprising a series of abutting wall insulation panels as defined in  claim 1 . 
     
     
         14 . The wall insulation cladding as claimed in  claim 13 , wherein the abutting wall insulation panels each comprise a VIP panel extending to two opposing sides of the wall insulation panel, for the wall insulation cladding to provide a continuous VIP plane. 
     
     
         15 . The wall insulation panel as claimed in  claim 6 , wherein the ribs or tubes extend wholly or substantially from the VIP facing surface to meet the VIP panel. 
     
     
         16 . The wall insulation panel as claimed in  claim 3 , wherein the expansion region includes ribs or tubes, and the ribs or tubes provide a corrugated surface between the VIP facing surface and the VIP panel. 
     
     
         17 . The wall insulation panel as claimed in  claim 16 , wherein the ribs or tubes extend wholly or substantially from the VIP facing surface to meet the VIP panel.
