Buy good quality low cost PIR Panel at Wedge India made of Steel, PIR (PolyIsocyanurate), Cement, MgO Boards, and FRP.  PIR (Polyisocyanurate) Panels are a type of sandwich panel similar to PUF panels but with enhanced fire resistance and thermal insulation properties. These panels are widely used in construction, particularly in buildings where high fire safety standards and superior insulation are required.
 
Key Features of PIR Panels:
1. Fire Resistance:
• Core Material: The core of PIR panels is made from polyisocyanurate foam, which offers better fire resistance than traditional polyurethane foam (PUF). PIR panels are self-extinguishing and char when exposed to fire, which helps prevent the spread of flames.
• Fire Rating: PIR panels typically achieve fire ratings such as B1 (low combustibility) or better, making them suitable for use in environments where fire safety is critical.
2. Thermal Insulation:
• Thermal Conductivity: PIR panels have very low thermal conductivity, typically around 0.018 to 0.023 W/m·K. This makes them highly effective at reducing heat transfer, contributing to energy efficiency in buildings.
• U-Value: Depending on the thickness, PIR panels can achieve U-values as low as 0.18 W/m²·K or better, making them one of the best options for thermal insulation.
3. Lightweight and Strong:
• Despite their enhanced fire resistance and insulation properties, PIR panels are lightweight, which eases handling and installation while providing significant structural strength.
4. Durability:
• The outer facings of PIR panels, usually made from galvanized steel, aluminum, or stainless steel, are highly durable, offering resistance to corrosion, weathering, and UV radiation. This ensures a long lifespan even in harsh environments.
5. Moisture Resistance:
• PIR panels are resistant to moisture, which helps prevent issues like mold growth, making them suitable for use in humid or wet environments.
6. Sound Insulation:
• Like PUF panels, PIR panels also provide sound insulation, making them suitable for use in noisy environments such as industrial facilities or near airports and highways.
7. Ease of Installation:
• PIR panels come in large sections with interlocking joints, which simplifies installation and reduces construction time. The panels are prefabricated, which also reduces on-site labor.
8. Aesthetic Options:
• PIR panels are available in various colors, profiles, and finishes, allowing for aesthetic customization to meet specific architectural requirements.

7. Fire Resistance:
• Rating: Typically B1 or better, with some panels achieving A2 (non-combustible) ratings depending on the outer facings and additives used in the core.
8. Water Absorption:
• Property: Very low water absorption, enhancing durability and performance in humid environments.
9. Sound Insulation:
• Sound Reduction Index (Rw): Typically ranges from 25 to 30 dB, with higher values possible depending on the panel thickness.
10. Weight:
• Panel Weight: Typically 10 to 30 kg/m², depending on the thickness and facing material.
11. Joint Design:
• Interlocking System: Tongue-and-groove or other interlocking profiles ensure tight, secure joints that minimize thermal bridging and air leakage.
12. Environmental Resistance:
• Corrosion Resistance: Enhanced by protective coatings on the outer layers.
• UV Resistance: High UV resistance due to the protective coatings, making PIR panels suitable for external applications.
13. Service Temperature Range:
• Operating Temperature: Typically -50°C to +100°C, making them suitable for a wide range of applications.
 
Applications of PIR Panels:
1. Industrial Buildings:
• Used in factories, warehouses, and processing plants where high fire resistance and insulation are required.
2. Commercial Buildings:
• Ideal for office buildings, shopping malls, and other commercial spaces where energy efficiency and fire safety are important.
3. Residential Buildings:
• Used in prefabricated houses, energy-efficient homes, and multi-story buildings.
4. Cold Storage Units:
• Essential for constructing cold rooms, freezers, and refrigerated warehouses where consistent internal temperature and fire safety are critical.
5. Roofing and Cladding:
• PIR panels are commonly used for roofing and external cladding in buildings due to their thermal efficiency and fire resistance.
6. Clean Rooms:
• Used in environments like laboratories, pharmaceutical manufacturing, and food processing areas where fire resistance and insulation are crucial.
7. Partition Walls:
• Suitable for creating insulated partition walls within larger buildings, providing both thermal and acoustic separation.
 
Installation Considerations:
• Structural Support: Ensure that the building framework can support the chosen panel size and weight. PIR panels, being lightweight, generally reduce the structural demands compared to traditional materials.
• Sealing: Proper sealing at joints is crucial to prevent air and moisture ingress, which maximizes the panel’s insulation and fire-resistant properties.
• Alignment: Panels must be correctly aligned and secured to ensure a tight fit, maintaining the integrity of the insulation and fire resistance.
