摘要： An insulated HVAC duct component such as a transition box includes a first insulation layer and a second, different insulation layer. The transition box includes at least four sidewalls and one of a top and a back wall, the transition box further including a first access port and a second access port, the first access port having a different cross section than the second access port, one of the access ports being spaced from a nearest sidewall by less than 2 inches. The first insulation layer is located along an inside surface of the box. The second different insulation layer overlies the first insulation layer, the second different insulation layer having an air impervious surface, wherein the combined thickness of the first insulation layer and the second different insulation layer is less than 2 inches.

摘要： Modularized insulation blanket for thermal and/or acoustical insulation. The modularized insulation blanket has a cover formed of a distal layer and proximal layer in sealed mated relationship. The distal and proximal layers are sealed along longitudinal and latitudinal heat-sealed seams that define a plurality of modules. The heat-sealed seam may be creased so as to be foldable and/or perforated to provide a tear line. Within the modules are batting blocks. The blankets may be attached to surface structures such as the interior skin surface of an aircraft fuselage, pipes or other structures with retention systems. The blankets may be formed in an apparatus including a platen, heat seal rollers or heating sealing mechanisms, and edge sealers.

摘要： An acoustical ceiling tile having an improved sound absorption value and having a dual layer of acoustical materials. The base mat layer has either no mineral wool or a low mineral wool content. The surface layer has a high mineral wool content which provides improved sound absorption values with or without perforating or fissuring the tile. The dual layer acoustical ceiling tile has a noise reduction coefficient (NRC) value of at least about 0.50.

摘要： Elongated ventilation duct comprising a fibre layer (2) without any splices and an inner layer (3) surrounding an elongated flow space (4), wherein



the fibre layer comprises mineral fibres and a binder, compressed into a desired duct shape, the fibres having a melting point over 800 degrees Celsius,
the inner layer is a stainless-steel foil having a thickness of 0.01-0.3 mm, facing the flow space.




A method of manufacturing a ventilation duct having a fibre layer (2) and an inner layer (3) of steel foil, wherein a binder solution is sprayed on the fibre layer, whereafter the fibre layer is compressed into a duct shape, having an elongated flow space (4), under heated conditions so that water in the binder solution evaporates, and bringing the inner layer into the flow space of the duct, which inner layer seals the flow space of the duct from the fibre layer.
