Introduction of PIR Pre-insulated HVAC Ductwork
PIR Pre-insulated HVAC Ductwork is a high-performance ventilation system engineered to redefine efficiency, durability, and safety in heating, ventilation, and air conditioning (HVAC) applications. Built around the exceptional properties of polyisocyanurate (PIR) foam, this prefabricated ductwork integrates insulation, structural integrity, and protective features into a single, ready-to-install solution-ideal for modern buildings across diverse climates and industries.
Why PIR Pre-insulated HVAC Duct stands out?
1. Superior Thermal Insulation
The PIR foam core acts as a thermal barrier, reducing heat gain in summer and heat loss in winter by up to 40% compared to uninsulated metal ducts. This translates to:
Lower HVAC system workload, cutting energy consumption by 30–50% annually.
Consistent temperature maintenance for conditioned air, ensuring optimal comfort in spaces ranging from homes to large commercial buildings.
2. Enhanced Fire Safety
PIR foam is inherently fire-resistant, and the ductwork meets stringent global safety standards, including:
ASTM E84 (U.S.): Classified as a low-flame-spread, low-smoke-density material.
EN 13501-1 (EU): Achieves Class B-s1, d0, indicating slow flame spread and minimal smoke/toxic gas emission.
GB 8624 (China): Certified as Class A, suitable for high-safety environments like hospitals and schools.
When exposed to fire, the foam forms a protective char layer that slows combustion and limits flame propagation.
3. Durability & Weather Resistance
Moisture Resistance: The closed-cell foam core repels water, preventing mold growth, insulation degradation, or structural weakening-even in humid regions (e.g., Southeast Asia, coastal areas).
Corrosion Protection: The outer metal facing resists rust and chemical damage, making it suitable for industrial facilities, laboratories, and coastal buildings exposed to salt air.
Longevity: With a service life of 15–25 years, the ductwork requires minimal maintenance, reducing lifecycle costs compared to traditional metal ducts that demand frequent re-insulation or repairs.
4. Efficient Installation & Versatility
Lightweight Design: Panels are 50% lighter than steel ducts, simplifying transportation, handling, and on-site assembly-reducing labor costs and project timelines.
Prefabricated Components: Elbows, tees, reducers, and straight sections are factory-made for precise fitting, cutting installation time by 30–50%.
Adaptable Sizing: Customizable to fit tight spaces (e.g., ceiling cavities, wall chases) or large-scale industrial layouts, with options for rectangular, circular, or oval configurations.
In summary, PIR Pre-insulated HVAC Ductwork combines cutting-edge insulation technology with rugged durability, making it a smart investment for any project seeking long-term efficiency, safety, and performance. Whether in tropical heat or freezing cold, this system delivers consistent results, ensuring optimal indoor environments while reducing operational costs.
