ALPHA-PIR panel

The ALPHA-PIR panel is a premium, lightweight pre-insulated Polyisocyanurate (PIR) air duct system. Featuring a fiber-free, formaldehyde-free foam core with aluminum foil facings, it delivers exceptional thermal performance (0.022 W/mK). As an eco-conscious solution, it contains zero ODP and has a GWP of less than 5, ensuring fire-safe and energy-efficient air distribution.

physical performance of ALPHA-PIR panel

In the HVAC field, the efficiency of air delivery is directly dependent on the airtightness and heat retention capacity of the ducts. The key indicators of ALPHA-PIR are not simply a low thermal conductivity coefficient, but rather the balance of its comprehensive physical parameters.

Thermal efficiency: Its thermal conductivity reaches 0.022 W/mK, which means that under the same insulation requirements, the thickness of its panels can be much thinner than that of traditional glass wool or rock wool products. This not only saves the space for the building ceiling but also reduces the overall weight of the ducts.
Structural strength data: According to the product specifications, its compressive strength is > 200 kPa, and its flexural strength is > 1200 kPa. The significance behind this data lies in that it enables the duct to operate under a high static pressure of 2000 Pa, with a wind speed of up to 25 m/s. This makes it capable of handling the demanding conditions in vertical main ducts of high-rise buildings or high wind-speed VAV variable air volume systems, without worrying about the increase in air leakage due to pipe deformation.

chemical stability and fire safety of ALPHA-PIR panel

Most decision-makers focus on the initial purchase cost, but the chemical formula of ALPHA-PIR provides risk hedging for long-term operations.

Zero damage and low emissions: This product employs CFC and HCFC free foaming technology, with an ozone depletion potential value (ODP) of 0 and a global warming potential value (GWP) less than 5. Against the backdrop of increasingly strict environmental regulations in various countries (such as the EU F-gas regulations), choosing such materials can effectively avoid future risks of green carbon taxes.

Stability under fire conditions: The core difference between PIR materials and ordinary polyurethane (PU) lies in their molecular structure. When exposed to fire, it can form a carbonized layer to prevent the spread of flames. According to the standards BS 476-6 and BS 476-7, its flame spread rating is Class 0 and Class 1. This characteristic provides valuable escape and rescue time windows in scenarios such as data centers and high-rise refuge floors.

Life Cycle Cost (LCCA) of ALPHA-PIR panel

Shift away from the sole consideration of material prices, and instead observe the efficiency gains in the installation and operation phases.

Installation efficiency lever: Due to the fact that the aluminum foil surface layer also has the function of a moisture-proof layer, its water vapor transmission rate is zero. This eliminates the need for an additional vapor barrier layer to be wrapped around the traditional ducts. Combined with its lightweight characteristic (the density of PIR is approximately 50-55 kg/m³), its installation speed is several times that of the traditional iron sheet ducts + insulation process. This "construction speed premium" is highly competitive in overseas markets with high labor costs (such as the Middle East and Europe).

Durability data: A structure with a closed-cell ratio of over 90% implies an extremely low water absorption rate (<3%). In a humid environment, this ensures the stability of the thermal conductivity over a long period, preventing the increase in cooling/heating energy consumption caused by the failure of the insulation layer due to water ingress.
