PIR pre-insulated duct system is a modern type of HVAC (Heating, Ventilation, and Air Conditioning) ductwork designed to efficiently transport conditioned air throughout a building. Its core feature is that the insulation is built into the duct's structure, eliminating the need to add it later.

 

. This foam is known for its excellent thermal properties and is often manufactured with environmentally friendly blowing agents that do not harm the ozone layer.

. For added durability, especially in outdoor applications, the facing can be a thicker aluminum sheet or pre-painted galvanized steel.

:

The PIR foam core has a very low thermal conductivity (approx. 0.022W/m·K), which is significantly better than traditional materials. This means it minimizes heat gain or loss from the air inside the duct, leading to substantial energy savings.

:

1/5th the weight of traditional sheet metal (galvanized iron) ducts. Because the insulation is built-in, the overall system is slimmer and requires less support structure, making it easier to handle and install.

:

High-quality PIR panels are manufactured to be fire-retardant. They can meet rigorous fire safety standards such as Class 0 (BS 476) and are designed to produce low smoke and toxic fumes.

:

The closed-cell structure of the PIR foam and the vapor-tight aluminum facings prevent moisture from penetrating the duct. This stops condensation (sweating) from forming on the duct surface, preventing water damage and mold growth.
