PIR Insulated Duct for HVAC System
PIR Insulated Duct is a duct system that utilizes polyisocyanurate (PIR) foam as its core insulation material. PIR foam boasts excellent thermal insulation properties, effectively minimizing heat transfer and reducing energy loss, making it widely applicable in heating, ventilation, and air-conditioning (HVAC) systems. The outer layer of this duct is typically protected by materials such as aluminum foil, which not only enhances the duct's strength and durability but also prevents damage to the insulation layer from the external environment. Moreover, the PIR foam insulated duct is easy to install and can be flexibly cut and assembled according to actual needs, significantly shortening the construction period. Its good fire-resistant performance also provides reliable safety assurance for buildings, making it an ideal choice for thermal insulation ducts in modern building HVAC systems.
