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) adhesive!} 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 loam (4). Alternatively, groups of VIP's (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 VIP's (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.
