Product Classification
1. Composition:
HY PIR PUR Sandwich panel
HUAYU
1. Composition:
Core Material: Both PIR and PU panels have a rigid foam core. PIR foam is an advanced version of PU foam that includes polyisocyanurate, enhancing its fire resistance and thermal insulation capabilities.
Facings: The foam core is enclosed between two facing materials, typically made of galvanized steel, aluminum, or fiber-reinforced plastic. These facings provide additional strength and protection.
2. Benefits:
Thermal Insulation: These panels offer superior thermal insulation, reducing energy consumption for heating and cooling. PIR panels generally have a lower thermal conductivity than PU panels, making them more efficient insulators.
Fire Resistance: PIR panels have higher fire resistance due to the chemical structure of polyisocyanurate, making them safer for use in buildings where fire safety is paramount.
Lightweight: Despite their strength, these panels are lightweight, which simplifies transportation and installation and reduces the structural load on buildings.
Durability: The robust facings and the closed-cell structure of the foam core make these panels highly durable and resistant to moisture and physical damage.
Moisture Resistance: The closed-cell foam structure provides excellent resistance to moisture ingress, preventing mold and mildew growth.
3. Applications:
Building Envelopes: PIR and PU panels are used in walls, roofs, and facades to provide effective thermal insulation in residential, commercial, and industrial buildings.
Cold Storage and Refrigeration: They are essential in cold storage facilities and refrigerated trucks due to their excellent insulation properties.
Clean Rooms: These panels are ideal for environments requiring stringent hygiene standards, such as pharmaceutical and food processing plants.
Agricultural Buildings: Used in barns, poultry houses, and greenhouses to maintain optimal temperature conditions.
1. Thermal Conductivity:
PIR panels typically have a thermal conductivity (λ) value of around 0.022 W/m·K, whereas PU panels have a λ value of around 0.024 W/m·K. Lower values indicate better insulation performance.
2. Fire Performance:
PIR panels are often rated higher for fire resistance, achieving classifications like Class 1 or Class 0, which indicate very low combustibility. This makes them suitable for buildings with high fire safety requirements.
3. Mechanical Strength:
Both PIR and PU panels offer high mechanical strength, with compressive strengths often exceeding 100 kPa. This ensures they can support significant loads and withstand impact.
1. Installation:
Ease of Installation: Their lightweight nature makes PIR and PU panels easy to handle and install, reducing construction time and labor costs.
Joint Systems: Many panels feature tongue-and-groove or lap joint systems, ensuring tight and secure installation, which minimizes thermal bridging and air leakage.
2. Maintenance:
Low Maintenance: Due to their durability and resistance to environmental factors, these panels require minimal maintenance.
Cleaning: The non-porous surfaces of the facings are easy to clean, maintaining hygiene standards in sensitive applications.
PIR and PU sandwich panels are crucial for modern construction, offering a blend of excellent thermal efficiency, fire safety, and structural integrity. Their versatility and ease of use make them a preferred choice in various industries, contributing to energy-efficient and safe building practices.
