Tecsonic 400 is a high quality fully flexible acoustic ducting.  It is ideal for use in high, medium amd low pressure ventilation and air conditioning systems where attenuation of duct borne noise is required.

Tecsonic 400 acoustic flexible ducting is manufactured with an inner core constructed from a multi-ply aluminium & polyester laminate to provide a tough yet highly flexible core.  This fabric is supported by an encapsulated high tensile steel wire helix at 35mm pitch.  This consruction reults in a 'sag free' yet ultra flexible duct in which smooth bends of less than 1/2 D radius can be produced.  The core is continuously perforated with micro perforations to enhance the acoustic performance of Tecsonic 400 whilst virtually eliminating the possibility of fibre migration.  This core is wrapped in a 25mm thick high density fibreglass blanket which is overlapped to ensure continuity of thermal and acoustic performance.  The insulation is then covered by a tough scuff resistant, reinforced aluminium and polyester laminate which acts as a vapour barrier.  This construction results in a highly flexible duct in which bends of 1/2 D radius can be produced.
