Key Features of Polyisocyanurate (PIR) Pre-Insulated Duct Panels & Ductwork Systems
Ultra-Lightweight PIR Pre-Insulated Duct Panel Construction
Our PIR pre-insulated duct panels weigh only 1/10 to 1/6 of conventional glass wool insulated sheet metal ducts. This lightweight design drastically reduces non-ferrous metal consumption, lowers the structural load on buildings and improves structural safety. It also eases on-site labor intensity and shortens the installation cycle of your HVAC duct system.
Sleek & Adaptable Finish for PIR Duct Panels
The smooth, flat surface of each PIR duct panel delivers a soft, refined visual effect. With an elegant, modern profile, these panels fit seamlessly into all types of commercial, industrial and residential installation scenarios.
Superior Sound & Vibration Dampening for HVAC PIR Duct Panels
The sandwich panel structure grants these HVAC PIR duct panels excellent sound insulation performance. Vibration and echo are fully absorbed by the insulation core layer, eliminating resonance issues and significantly enhancing indoor environmental comfort for occupied spaces.
High Structural Rigidity of Polyisocyanurate Duct Boards
Engineered with a scientifically designed reinforced duct system, polyisocyanurate duct boards offer outstanding compression and deformation resistance with a highly robust structure. Test data confirms that under an internal-external pressure differential of 500 Pa (both positive and negative pressure), no visible deformation or damage occurs to the finished duct body.
Industry-Leading Airtightness for PIR Air Duct Panel Systems (Zero Leakage)
Adopting a fully sealed system design without exposed seam joints, our PIR air duct panel achieves exceptional air tightness. Authoritative third-party tests verify that at a static pressure of +500 Pa, the air leakage rate of the entire duct system (including all connecting joints) reaches zero. This maximizes overall system operating efficiency and delivers optimal energy-saving performance.
Outstanding Dimensional Stability of PIR Duct Boards
Manufactured with integrated one-step high-pressure foaming technology and high-temperature interface bonding technology, our PIR duct boards maintain stable physical properties over decades of service: no surface deformation, no blistering and no delamination, guaranteeing long-term reliable operation of your duct system.
Ultra-Low Frictional Pressure Loss for PIR Ductwork Systems
The sandwich panel structure, paired with an aerodynamic obtuse-angle linear relief design on the inner PIR duct surface, provides built-in sound attenuation and optimized air flow. This eliminates the need for additional silencers, greatly reduces frictional resistance loss, cuts energy consumption, and lowers total installation and operating costs for your complete PIR ductwork.
Moisture & Acid Corrosion Resistant PIR Pre-Insulated Duct Systems
The insulation core of our PIR pre-insulated duct features a cyclic macromolecular structure with a 98% closed-cell rate, boasting extremely low water absorption. It effectively blocks the intrusion of moisture and acid mist, ensuring durable performance even in harsh industrial and outdoor environments.
