TDM Pre-insulated aluminium duct is developed as an alternative to the conventional ducting system. It is a sandwiched panel made of PIR (POLYISOCYANURATE) foam covered in smooth or embossed 80 micron aluminium foil (anti-mould & anti bacterial coated) . Nice in aesthetic, doesn't rust, non fibrous, zero permeability, anti mold and anti bacteria, contain no HCFC, lower air leakage, doesn't absorb moisture and fast installation speed.
All pre-fabrication work can be done before sending to the site, reduce wastages and much lesser workers needed at site . It is silent in operation at site.
TDM duct is very light weight, 6 times lighter than G.I. duct with insulation . This significantly reduced building load, roofing load and ceiling load. Also it uses less hanger , less labour and faster installation time. Suitable for commercial office buidings,factories and malls.
