A prefabricated composite insulation board

摘要

A prefabricated composite insulation board 1 comprises a facing 2 of a flexible sheet material and a plurality of vacuum insulation panels (VIP) 3 adhesively bonded thereto. A body of insulating foam 4 overlies the vacuum insulating panels 3 and the carrier 2. There are gaps 5 between adjacent vacuum insulation panels 3 and these gaps are filled with the foam 4. Alternatively, groups of VIPÆs 3 may be positioned close to one another and gaps 6 left at defined locations. These gaps 6 may be used to provide regions at which the panel may be cut to a desired length without cutting through and VIPÆs 3. External markings such as cut-lines 7 may be provided to indicated the location of these gaps 6. To manufacture a composite insulation board 1 of the invention on a continuous production line a facing sheet 2 with a pre-applied adhesive 6 is provided on a supply reel 10. The adhesive may be heat activated.
