The present invention provides methods and systems to effectively insulate hot or cold surfaces in industrial, domestic and building systems. It provides composite thermal insulation systems, which comprises an at least two-layer thermal insulation cladding, with at least two layers each containing from 25 to 95% by weight of aerogel and from 5 to 75% by weight of inorganic fibres, wherein the layers of the thermal insulation cladding are joined to one another by means of an inorganic binder.
