TSD 25 • Insulated flexible ducts

The semi-rigid TSD duct is a thermally and acoustically insulated duct. It consists of a double aluminium layer, 3-layers at overlapping areas. The outer layer is ribbed, for easy and clean cutting of the duct. The inner duct is perforated, thus preventing accumulation of particles inside the duct. The fibreglass insulation is covered with a glass film for long endurance, 50mm available on request. This particular construction is in accordance with the regulations stipulated in DIN 24146 at low pressure loss. Zinc coated steel end pieces are fixed on either side of the duct to facilitate connection to ductwork

• The TSD flexible ducts are used in ventilation, air conditioning, and air handling systems where high mechanical strength, temperature, fire-resistance, and thermal and sound attenuatin qualities are required
