PU Foam Pre-insulated Ductwork

PU Foam Pre-insulated Ductwork is a high-performance, all-in-one solution designed for modern heating, ventilation, and air conditioning (HVAC) systems.

Its sandwich structure consists of dense PU foam core with corrosion-resistant aluminum foil on both sides.

Factory prefabricated, it combines insulation, sturdiness and airtightness to simplify duct installation.

Polyurethane (PU) Foam Pre-Insulated HVAC Ductwork Panel

How does PU Foam Pre-insulated Ductwork enhance thermal insulation?

The sandwich structure of PU Foam Pre-insulated Ductwork achieves superior thermal insulation mainly through the following mechanisms:

1.High-density rigid PIR foam core with ultra-low thermal conductivity blocks heat transfer efficiently.

2.Double-sided aluminum foil reflects radiant heat and resists air penetration to reduce heat exchange.

3.Seamless integrated design removes air gaps and thermal bridges, preventing extra heat loss.

4.The compact composite panel cuts HVAC energy use and improves overall system efficiency.

Advantages of PU Foam Pre-insulated Ductwork

1. Excellent Thermal Insulation & Energy Saving

High-density PU foam core features low thermal conductivity (0.020–0.022 W/m·K) to curb heat transfer. It slashes HVAC energy use by 30–40%, lowering utility costs and supporting green buildings.

2. Reliable Fire Safety

Formulated with premium flame retardants, the foam forms a protective char layer in fire. It restrains flame spread and toxic fume emission, ideal for schools, hospitals and other public buildings.

3. Water Resistance & Long Service Life

Closed-cell PU foam repels water to avoid mold and insulation failure. Paired with corrosion-resistant metal facings, the panels maintain stable performance for 15–20 years with low maintenance needs.

4. Smooth Airflow & Good Indoor Air Quality

Smooth inner surface reduces air resistance and pressure drop for higher system efficiency. It also limits dust and bacteria buildup, perfect for venues demanding strict air quality.

5. Lightweight & Fast Installation

1/3 the weight of conventional metal ducts, the panels are easy to transport and handle. Standard modular design cuts installation time by half with guaranteed quality.

6. Wide Application & Great Flexibility

Applicable to residential, commercial and light industrial buildings. Customizable into diverse shapes for exposed or concealed duct setups to fit complex layouts.

PU Foam Pre-insulated Ductwork integrate superior insulation, fire safety and easy installation. They deliver economical, comfortable and sustainable air ventilation for all types of buildings.
