HY PIR PUR Sandwich panel
HUAYU
Polyisocyanurate (PIR) and Polyurethane (PU) sandwich panels are advanced construction materials known for their excellent thermal insulation properties. Here’s a detailed introduction to these panels:
1. Composition:
Core Material: The core of PIR/PU sandwich panels is made from rigid foam. PIR foam is a modified version of polyurethane that incorporates polyisocyanurate, enhancing its fire resistance and thermal performance.
Facings: The core is typically sandwiched between two facings made of materials such as steel, aluminum, or fiber-reinforced plastic. These facings provide structural strength and protect the foam core.
2. Benefits:
Thermal Insulation: PIR/PU panels offer superior thermal insulation, making them ideal for applications requiring controlled environments, such as cold storage, refrigerated trucks, and climate-controlled buildings.
Fire Resistance: PIR foam has enhanced fire-resistant properties compared to traditional PU foam, making PIR panels suitable for applications with stringent fire safety requirements.
Lightweight: Despite their strength, these panels are relatively lightweight, reducing the load on supporting structures and simplifying installation.
Durability: The robust facings protect the foam core, ensuring long-term durability and resistance to physical damage.
Moisture Resistance: The closed-cell structure of the foam provides excellent resistance to moisture and prevents mold growth, contributing to a healthier indoor environment.
3. Applications:
Building Envelopes: Used in walls, roofs, and facades of commercial, industrial, and residential buildings for effective thermal insulation.
Cold Storage: Essential in constructing cold storage facilities and refrigerated transportation for maintaining low temperatures.
Clean Rooms: Ideal for environments requiring strict hygiene standards, such as laboratories and pharmaceutical facilities.
Agricultural Buildings: Applied in agricultural structures like barns and greenhouses to regulate temperature efficiently.
1. Thermal Conductivity:
PIR panels generally have a thermal conductivity (λ) value around 0.022 W/m·K, while PU panels typically 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 for higher fire resistance, with some achieving Class 1 or Class 0 ratings, indicating very low combustibility. This makes them suitable for use in buildings where fire safety is a critical concern.
3. Mechanical Strength:
Both PIR and PU sandwich panels offer high mechanical strength, with compressive strengths often exceeding 100 kPa. This ensures they can withstand significant loads and impact.
1. Installation:
Ease of Installation: The lightweight nature of these panels makes them easy to handle and install, reducing construction time and labor costs.
Joint Systems: They often feature tongue-and-groove or lap joint systems to ensure tight and secure installation, minimizing thermal bridging and air leakage.
2. Maintenance:
Low Maintenance: Due to their durability and resistance to environmental factors, PIR/PU panels require minimal maintenance.
Cleaning: The non-porous surfaces of the facings make them easy to clean, maintaining hygiene standards, especially in food processing and healthcare applications.
PIR and PU sandwich panels represent a high-performance solution for modern construction needs, offering a blend of thermal efficiency, fire safety, and structural integrity. Their versatility and ease of use make them a preferred choice in various industries, contributing to energy efficiency and safety in buildings and facilities worldwide.
