PIR Ducting

Pre-insulated PIR panel ductwork, light, low-leakage and thermally efficient for air-conditioning distribution.

01Overview

PIR duct is formed from rigid pre-insulated panel with aluminium facings, so insulation and duct are a single element. That removes the separate lagging stage and gives a low thermal loss, low-leakage distribution system.

It is well suited to air-conditioning supply in ceiling voids where weight, installation speed and condensation control matter.

Typical applications

Air-conditioning supply distribution
Offices, hotels and retail interiors
Hospitals and clean environments
Refurbishment where structural load matters
Ceiling voids with restricted access

02How it works

Engineered as a complete air path.

01
Panel cutting
Panels are cut and grooved to the designed duct dimensions.
02
Assembly
Sections are formed, glued and sealed with aluminium tape and profiles.
03
Installation
Light sections are lifted and supported without heavy steelwork.
04
Sealing check
Joints checked for leakage before ceilings are closed.

03Design intent

Insulation built into the duct wall
Significantly lighter than insulated sheet metal
Low air leakage and reduced thermal loss
Smooth internal surface and quiet operation

04Questions

Common questions.

Where should PIR not be used?: It is not used for kitchen grease exhaust or high-temperature extraction, those runs are fabricated in GI.
Does PIR duct prevent condensation?: The insulated wall keeps the external surface above dew point in normal conditions, which is one of the main reasons it is chosen.
