Core Advantages
Superior Thermal Insulation
With an impressively low thermal conductivity of 0.018 - 0.022 W/(m·K), PIR duct foam panels offer outstanding heat resistance. Their high R - value, typically ranging from R - 6 to R - 6.5 per inch, minimizes heat transfer, ensuring stable indoor temperatures.
Energy Efficiency
Thanks to their excellent insulation properties, these panels significantly ease the burden on HVAC systems. By reducing the amount of energy required to heat or cool the air, they can cut long - term energy consumption by over 20% in a 30 - year lifespan.
Quick Installation
Weighing just 1.4 kg per square meter, the lightweight panels, combined with their user - friendly interlocking designs, streamline the installation process. Installation time can be slashed by up to 50% compared to traditional ductwork, as there's no need for a separate insulation step.
Moisture Resistance
The closed - cell structure of PIR foam is highly effective at warding off moisture. Water absorption rates are extremely low, at less than 0.1% according to ASTM C 209 - 15 standards. This prevents condensation from forming on the ducts, inhibiting mold and mildew growth.
Durable Construction
These panels can withstand high compressive strength, up to 0.2 MPa. They are resilient against handling during installation and can endure the operational stress of the HVAC system over time. With a lifespan of over 20 years, they offer long - term reliability, reducing the need for frequent replacements and maintenance.
Fire Safety
Meeting stringent fire ratings such as the BS 476 standard, PIR duct foam panels form a protective char layer on their surface when exposed to fire. This layer effectively blocks the spread of flames and significantly reduces smoke emission, with low opacity.
Space - Saving Design
Featuring a thin profile, these panels maximize usable space. In comparison to traditional insulation methods, they can save up to 200 mm in a single dimension.
Eco - Friendly
Formulated without CFCs or HCFCs, these panels are in line with green building standards. Additionally, they contribute to reducing a building's overall carbon footprint by enhancing energy efficiency.
