AluPIR Foam Panel
AluPIR foam board is a high-performance insulation panel made of PIR (polyisocyanurate) foam as the core material and double-sided composite aluminum foil. Its core advantages lie in extreme insulation, fire safety, moisture resistance, durability, light weight, and ease of installation. It is widely used in HVAC ducts, building envelopes, cold chain storage, and other scenarios.
Structure: Silver Aluminum/ PIR Foam/ Silver Aluminum
Size: 3950*1200*20mm
Foam Density: 50kg/m3
Aluminum Thickness: 0.06mm or 0.08mm
Aluminum Color: Silver
Packing: 10 sheets/ package
Loading Capacity: 710 sheets/ 40'HQ (packed with plastic bags)
660 sheets/ 40'HQ (packed with cardboard box)
Thermal Performance of AluPIR Foam Panel
Thermal conductivity λ = 0.02 W/m·K (25℃), far superior to EPS (0.038–0.042) and rock wool (0.040–0.045), with an increase in insulation efficiency of 30%+.
High thermal resistance R value: 20mm thick R = 0.8 m²·K/W; 40mm thick R = 1.6 m²·K/W, meeting the high insulation requirements of national standard GB 50176.
Aluminum foil reflective insulation: Infrared reflectivity > 90%, can block radiant heat, providing cooling in summer and insulation in winter, reducing HVAC energy consumption by 25%–35%.
Surface layer (aluminum foil): Thickness 0.06–0.08mm, embossed treatment, with functions of vapor barrier, anti-corrosion, and reflection. Water vapor permeability resistance μ > 100,000, almost no water vapor permeation.
Composite structure: Aluminum foil / PIR foam / aluminum foil, total thickness 10–40mm, standard size 3950×1200mm, integrated molding, no layering or cracking.
Fire Safety and Moisture-proof of AluPIR Foam Panel
1. Fire resistance rating: Meets GB 8624 B1 grade (flame retardant), oxygen index ≥ 32, self-extinguishes when away from fire, no dripping substances.
High temperature resistance: PIR heat distortion temperature > 180℃, can withstand 250℃ for a short period, far superior to PU (80℃), does not easily soften and collapse during a fire.
Low smoke and non-toxic: Burning smoke density ≤ 75, no toxic gas release, complies with building fire protection standards, suitable for densely populated places such as shopping malls and hospitals.
2. Moisture-proof and durable: Closed-cell vapor barrier, long service life
Closed-cell waterproofing: PIR has a closed-cell rate of over 95%, with an absorption rate of ≤ 0.2%. In long-term humid environments, the thermal conductivity remains stable, and it does not absorb water or develop mold.
Aluminum foil vapor barrier: The double-sided aluminum foil forms a sealed vapor barrier, completely blocking water vapor penetration, eliminating "cold bridge" condensation, and preventing dripping in the air duct and moisture re-entrainment on the wall.
Installation and Cost and Environment of AluPIR Foam Panel
1. Installation and Cost: Lightweight and Efficient, Cost Reduction and Efficiency Enhancement
Lightweight and High Strength: The surface density is approximately 1.5 kg/m². A 20mm thick plate weighs only 3 kg/㎡. One person can handle and install it, and no heavy equipment is required.
Easy Cutting and Joining: It can be sawed and grooved on-site. Special glue is provided for sealing, ensuring a tight joint without air leakage. The installation efficiency is increased by 50%, and the construction period is shortened by 30%.
2. Environment and Application: Green and Low Carbon, Wide Applications
Green and Environmentally Friendly: Free of CFC and HCFC, ODP = 0, GWP is extremely low, recyclable, compliant with LEED and Green Building Star standards.
Core Applications:
HVAC Air Ducts: Prefabricated insulated air ducts, replacing traditional iron sheets + insulation cotton, no cold bridges, no air leakage, energy saving by 30%+.
