A prefabricated composite insulation board comprises a facing of a flexible sheet material and a plurality of vacuum insulation panels (VIP) adhesive bonded thereto. A body of insulating foam overlies the vacuum insulating panels and the carrier. There are gaps between adjacent vacuum insulation panels and these gaps are filled with the foam. Alternatively, groups of VIP's may be positioned close to one another and gaps left at defined locations. These gaps may be used to provide regions at which the panel may be cut to a desired length without cutting through and VIP's. External markings such as cut-lines may be provided to indicated the location of these gaps.

1. The invention relates to silicic acid mixtures and use thereof as insulation material. 2.1 The problem to be solved by the invention was the providing of a cost-effective mixture based on silicic acid which can be used for insulation, wherein said mixture contains as small a volume as possible of chemically produced silicic acid and a high proportion of silicon-containing by-products or waste products, without substantially reducing the insulating properties. 2.2 This problem is solved by a mixture of silicic acid and more than 50 wt.-% silicon-containing ash, which contains no perlite, wherein the silicon-containing ash preferably comprises rice husk ash and silica fume. The invention further relates to a method for producing insulation material by producing the mixture according to the invention and introducing the mixture into a sleeve, wherein no sintering step occurs in the method. Mixtures of differing compositions were correspondingly processed into a vacuum insulation panel and the insulating properties were compared based on the measured thermal conductivity. 2.2 The mixture according to the invention can be used as an insulation material, in particular for housing insulation.
