    • According to a method for applying an insulating layer to a surface fibers, of an inorganic material an sprayed onto the surface under simultaneous wetting of the fibers with water and/or a binder so that the fibers stick to the surface whereafter the layer is formed and dryed/hardened. Prior to or after the drying/hardening a binder can be sprayed to the surface for the purpose of achieving a dustless and mechanically resistant surface layer. A device for applying of an insulation to a surface of an object (10), making use of the method, comprises a store (41) of fibers of an inorganic material, a conduit (20) for the transfer fibers from the store (41) to a spray nozzle (21) and device for generating an air flow in the conduit (20) directed towards the nozzle (21). Further, the device includes a first ejector (22) provided at the end of the conduit facing the store (41) for introducing air jets into the conduit (20) in the direction of the fiber stream but at an inclination with respect to the stream, a second ejector (23) disposed at the end of the conduit facing the spray nozzle (21) for the introduction of air jets directed so as to bring the fiber stream into rotation, and a device (24) disposed adjacent to the spray nozzle (21) for introducing into the fiber stream, but outside of the spray nozzle, of liquid jets in the direction of the fiber stream but forming an angle with the stream, the liquid jets comprising a mixture of water and a binder.
