UNT Pre-insulated Duct Material Overview

The UNT Pre-insulated Duct Material is a new - generation HVAC pipeline system developed and produced by UNT Company. It adopts an innovative composite structure design, integrating the conveying pipeline, insulation layer, and outer protective layer, providing efficient and convenient fluid transportation solutions for commercial and industrial buildings. The product has passed the Australian standard AS 1530.3 - 1999, ISO9001 quality management system certification, and ISO14001 environmental management system certification. It complies with international standards such as EN253 and ASTM C547, and is widely used in heating, cooling, and industrial pipeline projects in more than 50 countries around the world.

Why Choose Pre-insulated Duct Material?

Polyurethane / Polyisocyanurate composite duct board (Polyisocyanurate is abbreviated as PIR) has a thermal conductivity as low as 0.020W/m·K, which significantly reduces the heat loss of the central air - conditioning system. In addition, the polyurethane composite duct board also has the advantages of light weight, long service life, and is easy to install, which can greatly shorten the construction period of air - conditioning ducts.

Material	Thermal Conductivity (W/mK)	Bending Strength (MPa)	Compressive Strength (KPa)	Thermal Resistance (m²·K/W)
Polyurethane	0.02	2	250	0.99
XPS	0.035	0.4	200	0.02
EPS	0.031	0.15	75	0.095

The excellent closed - cell structure of rigid polyurethane gives it a low thermal conductivity and excellent heat - insulation performance.

Made of carefully selected high - quality materials, with a variety of composite surface materials available, the product quality is guaranteed without cutting corners.

The thermal conductivity of the polyurethane composite board is as low as 0.020W/m·K, which is lower than that of other thermal insulation materials, and its heat - insulation performance is better.

The polyurethane composite duct is light - weight, high - strength, sound - insulating, heat - insulating, non - combustible, waterproof and moisture - proof, and the installation process is simple and environmentally friendly.
