<p>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.</p> |
