Alu Acoustic is flexible sound-absorbing and thermally insulated ducting with Aluminium micro-perforated ducting on the inside. It is lined with 25 mm thick polyester fibre insulation and is covered on the outside with multilayer aluminium/polyester jacket to give an excellent vapour-barrier and prevent condensation forming. The outstanding sound absorbing and noise reduction features are guaranteed by special micro-perforations on the internal ducting which break up sound waves so they cannot propagate inside Alu Acoustic ducting.
