    The invention further relates to a method of producing a mineral wool silencer for air conditioning, wherein the silencer comprises a mineral wool construction having a duct-forming through-cavity open at two ends, wherein the mineral wool construction may be located between a ventilation unit and a ventilation pipe system or at a location along a duct or ducts in a ventilation pipe system such that the duct forming cavity of the mineral wool structure becomes part of the air duct or air ducts of the ducting system, the surface of the duct wool duct forming cavity being coated with a material which prevents the release of mineral wool particles for ventilation.
    The air-conditioning silencer is a block which can be placed between a ventilation unit and a ventilation pipe system, and which is intended to absorb unit-generated noise in the pipe system.
    A typical silencer construction is (layers from the inside): a fiberglass cloth that can be cleaned, an insulation layer of stone wool, an outer sheet of sheet metal.
    2 DK 2013 00094 U1
    Retrofitting stone wool elements and sheets coated with fiberglass cloth inside a sheet metal cage incurs extra labor costs. Furthermore, an outer sheet of sheet metal is a more expensive material than an aluminum / fiberglass laminate used in its manufacture.
    The present makers have found that the replacement of an outer sheet metal sheet with an aluminum / fiberglass laminate results in savings not only in material costs but also in labor costs, as it is possible to fabricate an installation-ready silencer at the factory.
    The silencer according to the invention is new in that an outer surface of the mineral wool construction is coated with an aluminum / fiberglass cloth laminate.
    In a preferred embodiment of a silencer according to the invention, the coating material consists of the inner surface of a mineral wool construction of fiberglass cloth.
    The mineral wool construction of a silencer according to the invention is preferably tubular in shape, in a particularly preferred case being made of a mineral wool insulation or pipe section. In a further preferred case, the cavity of the mineral wool structure of a silencer according to the invention has a substantially cylindrical shape, and the outer surface of the mineral wool structure has a substantially rectangular or cubic shape. In yet another preferred case, the mineral wool construction of a silencer according to the invention has both ends at which the cavity is open, provided with metal collars by which the silencer can be connected in place between a ventilation unit and a ventilation pipe system or at a location along the ventilation pipe system between air ducts.
    The process according to the invention is new in that an outer surface of the 3 3DK 2013 00094 U1 mineral wool structure is coated with an aluminum / fiberglass cloth laminate.
    In a method according to the invention, it is preferred that the mineral wool construction be made of a tubular block of mineral wool, in a particularly preferred case being made from or cut from a mineral wool pipe insulation, ie. a pipe section.
    A preferred embodiment of the method of manufacture comprises: splitting the tubular block of mineral wool longitudinally across, coating the inner half-cylindrical surface of both halves with the material which prevents the release of mineral wool particles for ventilation, gluing the halves with coated inner half-cylindrical surfaces together to form a tube, to coat the resulting tube over its outer cylindrical surface with the aluminum / fiberglass laminate.
    Another preferred embodiment of a method according to the invention comprises: coating the outer cylindrical surface of a tubular block of mineral wool with the aluminum / fiberglass laminate, whereby the thus coated dew is cleaved in the middle over coating both half inner inner cylindrical surface with a material which prevents discharge of mineral wool particles for ventilation, to glue the halves with coated inner semi-cylindrical surfaces together to form a tube, and to seal the joints of the outer cylindrical surface with a tape.
    It is further preferred by a method according to the invention that a portion of both split surfaces of both pipe halves is also coated with the material which prevents the release of mineral wool particles for ventilation so that the coating in each half is allowed to extend continuously past both inner edges of the cleavage.
