What is PIR Aluminium Duct ?
PIR Aluminium Duct refers to a type of composite duct that uses polyisocyanurate (PIR) foam as the insulation core material and aluminium foil or aluminium sheet as the facing material. Here is a detailed introduction:
Structural composition of PIR Aluminium Duct
Structural composition: It is generally composed of a core material and a facing material. The core material is PIR foam, which has a closed - cell rate of up to 95%. The facing material is usually aluminium foil, aluminium sheet, etc. For example, the PIR pre - insulated duct panel may have 80 - micron aluminium foil or 200 - micron aluminium sheet on both sides.
Performance advantage of PIR Aluminium Duct
Core Advantage
Heat insulation and energy conservation:
Due to the low thermal conductivity of PIR foam, the air duct has an extremely strong heat insulation effect, which can effectively reduce energy loss.
Good sound insulation performance:
The closed-cell structure of PIR foam has excellent shock absorption and sound insulation performance, and there will be no noise problems such as vibration and echo, providing a quiet and comfortable environment for the space.
Easy to install:
PIR air ducts are lightweight. For instance, a 20mm thick PIR sheet weighs only 1.4kg per square meter, which is 1/10 the weight of traditional iron sheet air ducts. This makes them convenient for transportation and on-site fabrication and installation, saving a significant amount of transportation and labor costs.
Long service life:
The surface material of PIR air duct board has anti-corrosion performance, and combined with the stability of PIR foam itself, the service life of the air duct can reach more than 20 years.
