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.
