P3 Insulation Brisbane & Queensland
P3 Ducting & Plenums: Pre-insulated aluminium panels
P3 insulation is a lightweight, cost-effective and simple-to-install pre-insulated panel system for HVAC ductwork. Made with 20mm phenolic insulation in black and silver varieties, it’s used to build both duct runs and plenum HVAC boxes — with the insulation already built in, so there’s no separate lining to install.
We organise the construction and supply of P3 insulated ducts and plenums Queensland-wide, so you can deliver quality insulation and ducting projects on time.

What is P3 Insulation?
P3 insulation uses pre-insulated aluminium panels to build HVAC ducts for air conditioning and ventilation systems. The panels are made with phenolic insulation and come in black and silver varieties.
Compared with traditional galvanised sheet metal ducts, P3 panels are lighter and more cost-effective, and the insulation comes built in. That makes them ideal for projects with space or weight restrictions, in both large and small systems — from commercial buildings to schools.

Tee Pieces
Incorporate P3 ducting into your HVAC system’s tee pieces as a cost-effective alternative to sheet metal ducting.
How P3 Ducting and Plenums Work
P3 is one of the most hygienic, fire-resistant duct systems available. Like all ducts, P3 ducts and plenums control the distribution of air at the right temperature throughout every room in a system. Because the panels are lightweight and rigid, they’re a natural fit for narrow, constrained projects that need space- and energy-saving solutions.
P3 ducts offer strong resistance to extreme conditions, including fire, smoke and earthquakes. They also help prevent dust and solid particles from settling in your ventilation system. P3 duct panels can have self-cleaning properties, with a unique coating developed to simplify routine maintenance and cleaning.
P3 duct vs plenum: what's the difference?
P3 duct
The run of ductwork that carries conditioned air from one point to another.
Plenum
The larger box that collects or distributes air, typically sitting on the air handling unit or where air splits into several duct runs.
Both are fabricated from the same P3 panels, providing consistent insulation performance throughout your HVAC system.
Benefits Of Our P3 Type Duct Panels
Ease of Transport, Construction & Installation
P3 ducts are lightweight and portable, with coded construction procedures that make on-site assembly fast and reduce manual-handling risk.
High thermal insulation
P3 duct panels have built-in insulation that helps reduce heat transfer and energy loss. This keeps heated or cooled air closer to its intended temperature as it moves through the ductwork, supporting better energy efficiency across your HVAC system.
Improved Indoor Air Quality
The insulated panels help reduce the risk of condensation, which can help prevent mould growth when the ductwork is properly installed and maintained. Treated panel surfaces can also support hygiene throughout the ventilation system.
Fire & Smoke Protection
P3 panels meet international fire safety standards. In the case of a fire, the panels’ composition can help reduce smoke emissions and any associated risks.
Earthquake Resistant
The light and rigid nature of the panels reduces the likelihood of movement or deformation and any subsequent faults.
P3 Insulation vs Traditional Sheet Metal Ducting
P3 ducting is a cost-effective alternative to sheet metal: it’s lighter to move, faster to install, and arrives already insulated — saving you time and labour costs on every project.

Frequently asked questions
Both belong to the same ductwork category. Square ducts have equal width and height dimensions, while rectangular ducts have different dimensions on adjacent sides. The terms are often used interchangeably when discussing rectangular metal duct systems.
Yes. Square and rectangular ductwork can be insulated using suitable external insulation materials or constructed using appropriate pre-insulated duct panels. The insulation method depends on the operating conditions, thermal requirements and project specifications.
Duct dimensions are typically determined by airflow calculations, available installation space and project drawings. Material thickness, section length and connection details may also vary. Contact AIandHS with your specifications to confirm available options.
Yes, where a square or rectangular duct connects directly to a round spiral duct, a suitable transition fitting is generally required. The transition must match the dimensions and connection requirements of both sections.
