PIR Aluminium Ductwork

PIR Aluminium Ductwork serve as core high-performance components for modern HVAC ventilation systems.

Constructed with a premium sandwich structure combining double-sided aluminium foil and rigid PIR foam core, this integrated duct solution fully replaces conventional galvanized steel ducts that require separate on-site insulation work.

It streamlines construction procedures, cuts overall project costs and delivers superior thermal insulation, airtightness and structural stability.

Widely applicable to a broad range of commercial and public facilities, including hotels, office buildings, airports, hospitals, shopping malls and other large-scale buildings with demanding ventilation requirements.

Mechanical Strength & Stability of PIR Aluminium Ductwork

PIR Aluminium Ductwork panels feature outstanding compressive strength and superior bending resistance. Thanks to their robust composite structure, the panels can withstand various external loads, mechanical stress and construction impacts.

This reliable mechanical performance effectively prevents structural collapse, surface cracking and other forms of mechanical damage throughout installation, transportation and long-term operational service, maintaining intact duct structure and stable running conditions all the time.

After full curing, the finished panels maintain outstanding dimensional stability.

They will not suffer from shrinkage, expansion or warpage when exposed to varying ambient temperature and humidity, ensuring long-term reliable structural performance.

Production and Installation of PIR Aluminium Ductwork

Two production technologies are applied to fabricate PIR Aluminium Ductwork: industrial continuous foaming in workshop and field spray foaming.

Factory-manufactured boards maintain uniform density across the entire panel and strict dimensional precision, which fully meets the requirements of standardized mass production and unified construction standards.

Field spray foaming technology is specially designed for non-standard pipelines and complex building structures. The sprayed PU foam adheres seamlessly to the base surface without forming any insulation dead areas. This core merit distinguishes it from other insulation materials and cannot be substituted.

In terms of installation performance, the material exhibits great workability. Its flexible texture allows easy cutting and processing, eliminating the need for heavy professional equipment. The whole installation process can be independently completed by one worker. Furthermore, the board has powerful adhesive force. It forms a durable bond with color steel panels, iron sheets, cement mortar and other base materials, with strong resistance to peeling and detachment throughout the service life.
