The present invention relates to a multilayer laminate comprising at least three layers, wherein the two outer layers are each nonwoven backing sheet (7) containing a crystalline silicate mineral powder impregnated with a coating of an impregnating resin based on acrylate derivatives, which is suitable for increasing the compactness of the insulating sheet and for preventing the silicate mineral powder from detaching from the aramid fiber during use; the multilayer laminate having an inner layer being free of crystalline silicate mineral powder that comprises either i) heat resistant floc and binder, or ii) heat resistant polymeric film. The impregnating resin also comprises an organic solvent, which is capable of reducing the viscosity thereof and of promoting its deep penetration into the sheet. In addition, the impregnating resin comprises a UV polymerization photoinitiator which is suitable for curing the resin, only after said resin has been applied to the sheet and has penetrated deeply therein.
