Abstract: The present invention relates to a process for the preparation of a composite for thermal insulation comprising at least layers (L1), (L2) and (LB), the process comprising the steps of providing layer (L1) containing from 25 to 95% by weight of aerogel and from 5 to 75% by weight of fibers and from 0 to 70% by weight of fillers and layer (L2) containing from 25 to 95% by weight of aerogel and from 5 to 75% by weight of fibers and from 0 to 70% by weight of fillers; applying a composition (C1) comprising an inorganic binder on one surface of the layer (L1) or layer (L2) or layer (L1) and (L2), and combining layer (L1) and layer (L2) in a manner that composition (C1) is located between layer (L1) and (L2), wherein composition (C1) is applied in the form of a, as well as a composite for thermal insulation comprising at least layers (L1), (L2) and layer (LB) which is located between layers (L1) and (L2) and the use of said composite for thermal insulation.
