PIRALU Pre-Insulated duct system is an innovative technology for ACMV ductwork, the rigid polyisocyanurate panel is used as an alternative of traditional GI for operation such as fresh air, supply, return and exhaust air ductwork for ACMV system.

These panels feature a unique sandwich construction that is the result of injecting polyisocyanurate(PIR) as the core material laminated with aluminum facing on both sides. These panels are suitable for the construction of air distribution ducts in air-conditioning and heating systems.



The material's main characteristics are: superior thermal K value, a high level of rigidity and lightness, antimicrobial treatment surface, extremely easy to handle and install.

PIRALU Pre-Insulated Duct System is specially developed for use in residential, commercial and industrial units of ACMV duct system to satisfy the thermal, airflow, fire and easy to installation requirement.



PIRALU Pre-Insulated Ducting System is the first Singapore Green Building Council certified pre-insulated duct product, low VOC certified.



The Class 0 panel also conforms to all SCDF requirements and the relevant test reports are certified under TÜV SÜD PSB. PIRALU Pre-Insulated Duct System protects the surface from the spread of flames and limits the amount of heat released from the surface during a fire.
