Product Definition and Core Structure Of UNT Pre-insulated PID Duct Panel

The pre-insulated PID air duct panel is a modular ventilation system component that integrates the insulation layer and the structural layer. It adopts a sandwich structure design and is composed of an outer protective layer, an middle insulation layer and an inner sealing layer.

Panel Structure: Silver Alu. / Blue PIR Foam / Silver Alu. Foil
Foam Density: 50-55kg/cbm
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 0.06mm or 0.08mm (Embossed)
Packing: 10 sheets/ Cardboard box

Core Technologies and Performance Characteristics of UNT Pre-insulated PID Duct Panel

(1.) High-efficiency heat insulation performance

The low thermal conductivity of PIR foam can reduce heat loss in air conditioning systems by more than 30%. The outer layer of aluminum foil forms a reflective barrier, further reducing the transfer of radiant heat.

(2.) Lightweight and structural strength

It weighs only 1.4 kilograms per square meter, making it easy to handle and install. Meanwhile, its compressive strength reaches 0.25 MPa and its flexural strength is 2 MPa, capable of withstanding conventional mechanical stress.

(3.) Fire prevention and safety certification

The PIR panel has passed the BS 476 fire resistance test. When burning, it forms a carbonized layer to prevent the spread of flames and does not release any harmful gases.

(4.) Long-lasting durability

The aluminum foil layer is resistant to ultraviolet rays and chemical corrosion. The water absorption rate of PIR foam is less than 1%, which can maintain stable performance in a humid environment. The service life of the system exceeds 20 years, and the maintenance cost is reduced by more than 50% compared with traditional air ducts.

Market Advantages and Competitive Barriers of UNT Pre-insulated PID Duct Panel

(1.) Innovation in installation efficiency

The modular prefabricated design reduces on-site cutting, and the installation time is 40% shorter than that of traditional air ducts. The supporting tools (such as CNC cutting machines and sealant guns) support quick assembly and are suitable for renovation projects or projects with tight schedules.

(2.) Full life cycle cost advantage

Initial cost: It is 10-15% higher than that of traditional galvanized iron sheet air ducts, but the energy-saving benefits will offset the price difference within 3-5 years.

Long-term benefits: Reduced maintenance frequency (such as no need to replace the insulation layer regularly), and lower operating costs.

(3.) Green sustainability

The material is recyclable and meets the requirements of LEED certification. The production process of PIR foam does not emit chlorofluorocarbons (CFCS), contributing to the goal of carbon neutrality.

(4.) Technical barriers

Material formula: PIR foam with a closed-cell rate of over 95% requires a precise foaming process, which only a few domestic manufacturers have mastered.

Sealing technology: Ensure long-term airtightness.
