PU Composite Duct Boards

Featuring high-performance PU foam as the core substrate, PU Composite Duct Boards are lightweight composite materials that combine thermal insulation, structural strength and certified fire resistance as a complete assembly, widely applied in HVAC construction.

This integrated modular duct solution reduces system energy loss, expedites on-site installation, and sustains stable ventilation efficiency during long-term operation.

Material structure and specification system of PU Composite Duct Boards

UNT PU Composite Duct Boards are built with a sandwich structure: rigid PU foam core enclosed by double-sided aluminum foil protective layers, granting the panel great physical advantages.

Complete size and thickness selections support all types of engineering needs:

Thickness: 10–40 mm full range, 20 mm as common size for different wind pressure and insulation needs

Standard Sizes: Lengths 3950 / 2950 / 2900 mm, fixed width 1200 mm, easy to ship, cut and install on site

Surface Foil Types: • 80 micron embossed aluminum foil: Ordinary indoor ventilation • 200 micron aluminum sheet / color steel sheet: Outdoor & high bending strength scenarios • Plain smooth aluminum foil: Hospital, pharmaceutical and other clean ventilation projects

Quick installation and low maintenance costs of PU Composite Duct Boards

Quick installation

Compared with the complex process of traditional Air ducts that require on-site cutting, welding and wrapping of insulation layers, Polyurethane Air Duct Panel adopts a modular design. It can be prefabricated into standard sections or special-shaped parts according to the construction drawings and spliced on-site with special connectors. The installation efficiency is increased by more than 50% and the construction period is shortened.

Low Maintenance Expense

Its smooth surface prevents dust buildup and reduces duct cleaning cycles. Boasting excellent anti-ageing performance, the panel lasts over 20 years under normal service. Subsequent maintenance costs are only 25% of traditional air ducts.
