Products Description of Pre-insulated PID Sheet
PI Duct, namely Pre-Insulated Duct, is a key innovative product in the heating, ventilation and air conditioning (HVAC) system. Its structure usually adopts a sandwich design, with polyisocyanurate (PIR) foam or phenolic foam, etc. as the core insulation layer.
Take PIR foam as an example. It is sandwiched between two layers of aluminum foil. The aluminum foil not only enhances the stability of the overall structure but also further improves the heat insulation capacity. For instance, common specifications include 3950mm * 1200mm * 20mm. Such size designs are convenient for transportation and installation.
Performance advantage of Pre-insulated PID Sheet
Excellent fire resistance performance:
The PID Duct with PIR foam as the insulation layer has self-extinguishing foam itself and can automatically stop burning when exposed to a fire source. The PID Duct made of phenolic foam has more outstanding fire resistance performance and generates very little smoke and toxic gases at high temperatures.
Lightweight and easy to install:
Compared with metal air ducts, PID ducts are extremely light in weight, which reduces the load-bearing pressure on the building structure and support points, and lowers the labor and material costs required for installation. Meanwhile, it can be conveniently processed into various shapes on the construction site, reducing transportation costs.
Application scenarios of Pre-insulated PID Sheet
Civilian residences:
Whether installed indoors or outdoors, visible or combined with false ceilings, PID Duct can achieve good heating, ventilation and air conditioning effects in residences, enhancing living comfort.
Industrial field:
In industries such as food processing, electronics, pharmaceuticals, hospitals and medical centers, PID Duct provides ventilation solutions of high quality and high hygiene standards to ensure the stability of production and medical environments.
