Introduction of Polyisocyanurate (PIR) Pre-insulated Duct Boards
feature a sandwich structure that directly integrates PIR insulation boards with metal facing materials (such as aluminum foil), eliminating the need for separate insulation installation. These boards are employed in fabricating air ducts for HVAC (Heating, Ventilation, and Air Conditioning) systems. This all-in-one design enhances efficiency, shortens installation time, and ensures consistent thermal performance.
Panel Structure:
Inner/Outer Facing Material: 60 Micron Aluminum Foil
Core Material: 52kg/Cbm PIR Foam
Regular Dimension: 3950mm*1200mm*20mm
Packing: 10 Sheets/ Packages
Key Components of Polyisocyanurate (PIR) Pre-insulated Duct Board & Its Structure
typically consists of three main layers (same as sandwich):
Inner Facing Material:
The aluminum foil-either embossed or smooth-that comes into contact with airflow features an anti-microbial coating. This coating resists corrosion, prevents dust accumulation, and ensures the distribution of clean air.
Insulation Core:
At the center of the sandwich structure lies the polyisocyanurate (PIR) foam, characterized by low thermal conductivity and an excellent closed-cell structure-properties that resist moisture while delivering superior heat retention and prevention of heat loss.
Outer Facing Material:
A protective facing material-typically aluminum foil or aluminum sheets-safeguards the insulation core against physical damage and moisture.
