2090871 9301444 PCTABS00019 According to a method for applying of an insulating layer to a surface fibres of an inorganic material is sprayed onto said surface under simultaneous wetting of the fibres with water and/or a binder so that the fibres 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 fibres of an inorganic material, a conduit means (20) for the transfer of fibres from the store (41) to a spray nozzle (21) and means for generating of an air flow in the conduit means (20) directed towards the nozzle (21). Further, the device comprises first ejector means (22) provided at the end of the conduit facing the store (41) for introducing air jets into said conduit means (20) in the direction of the fibre stream but at an inclination with respect to said stream, second ejector means (23) disposed at the end of the conduit means facing the spray nozzle (21) for the introduction of air jets directed so as to bring the fibre stream into rotation, and means (24) disposed adjacent to the spray nozzle (21) for introducing into the fibre stream, but outside of the spray nozzle, of liquid jets in the direction of the fibre stream but forming an angle with said stream, said liquid jets comprising a mixture of water and a binder.
