A composite thermally insulating material suitable for use in houses, which can manifest high thermal insulation performance when packed into the restricted cavity between outer and inner walls. The composite is constructed from two sheet- shaped fibre-based thermally insulating materials 6 and a vacuum thermally insulating material 7 which is incorporated (interposed) between these fibre-based thermally insulating materials 6. It is preferred that the region between the fibre-based thermally insulating materials 6 and vacuum thermally insulating material 7 be secured with adhesive agent. |
