Buy good quality PUF Panel Roofing Sheets at Wedge India made of Steel, Aluminium, and PUF Polyurethane Foam. PUF (Polyurethane Foam) panel roofing sheets are an excellent solution for creating insulated roofs in various types of buildings. These roofing sheets combine the benefits of thermal insulation, durability, and lightweight construction, making them ideal for both industrial and commercial applications.
 
Key Features of PUF Panel Roofing Sheets:
1. Thermal Insulation:
• Core Material: The core of PUF roofing sheets is made from rigid polyurethane foam, which provides excellent thermal insulation. This helps in maintaining a stable internal temperature by reducing heat transfer, making the building energy-efficient.
• U-Value: PUF roofing sheets typically have a low U-value, meaning they offer high resistance to heat transfer.
2. Lightweight Construction:
• PUF roofing sheets are significantly lighter than traditional roofing materials, which reduces the overall load on the structure. This makes them easier to handle, transport, and install.
3. Durability and Weather Resistance:
• The outer layers of PUF roofing sheets, usually made from materials like galvanized steel, aluminum, or pre-painted galvanized iron (PPGI), are designed to withstand harsh weather conditions, including heavy rain, snow, and UV radiation. This ensures a long lifespan for the roofing system.
• They are also resistant to moisture, preventing problems like rust or mold growth.
4. Fire Resistance:
• While standard PUF panels offer moderate fire resistance, fire-retardant versions are available for roofing applications where enhanced fire safety is required. These panels are treated with fire-retardant chemicals to meet specific safety standards.
5. Quick and Easy Installation:
• PUF roofing sheets are prefabricated and come in large sections with interlocking joints, which simplifies the installation process. This reduces labor costs and construction time.
6. Aesthetic Flexibility:
• PUF roofing sheets are available in various colors, profiles (such as corrugated or trapezoidal), and finishes, allowing for customization to match the building’s architectural style.
7. Acoustic Insulation:
• These panels also provide sound insulation, which can be particularly beneficial in industrial settings or areas with high external noise levels.
 
Technical Specifications of PUF Panel Roofing Sheets:
1. Core Material:
• Density: Typically 36 to 40 kg/m³ (±2 kg/m³).
• Thermal Conductivity (K-value): 0.019 to 0.023 W/m·K.
2. Outer Layer (Facing):
• Material Options:
• Pre-painted Galvanized Steel (PPGI): 0.4 to 0.8 mm thick.
• Aluminum: 0.4 to 0.8 mm thick.
• Stainless Steel: 0.4 to 0.8 mm thick, often used in environments where corrosion resistance is essential.
• Surface Finish: Can be smooth, ribbed, or profiled (e.g., corrugated or trapezoidal) depending on the aesthetic and functional requirements.
3. Panel Thickness:
• Range: Typically 30 mm to 150 mm, depending on insulation requirements.
• Common Thickness for Roofing: 40 mm, 50 mm, 60 mm, 80 mm, 100 mm.
4. Panel Width:
• Effective Width: Usually 1000 mm to 1200 mm.
• Overall Width: Slightly larger due to the design of the interlocking joints.
5. Panel Length:
• Standard Length: Up to 12 meters, with custom lengths available to suit specific project needs.
6. Thermal Insulation:
• U-Value: Ranges from 0.19 W/m²·K to 0.65 W/m²·K depending on the thickness and core density.
7. Fire Resistance:
• Rating: Typically B2/B3 according to DIN 4102, with fire-retardant options available.
8. Load Bearing Capacity:
• Designed to withstand typical roofing loads, including snow, wind, and maintenance loads, depending on the panel thickness and the specific structure.
9. Water and Air Tightness:
• Panels feature interlocking systems (such as tongue-and-groove) and are often installed with sealants or gaskets to ensure they are water and air-tight.
10. Weight:
• Panel Weight: Typically ranges from 10 to 30 kg/m², depending on thickness and facing material.
11. Service Temperature Range:
• Operating Temperature: Typically from -50°C to +80°C, making them suitable for a wide range of climatic conditions.
 
Applications of PUF Panel Roofing Sheets:
1. Industrial Buildings:
• Ideal for factories, warehouses, and industrial sheds where insulation, durability, and ease of installation are crucial.
2. Commercial Buildings:
• Used in shopping malls, office buildings, showrooms, and other commercial spaces where energy efficiency and aesthetic appeal are important.
3. Residential Buildings:
• Suitable for energy-efficient homes, prefabricated houses, and residential extensions.
4. Cold Storage Facilities:
• PUF roofing sheets are often used in cold storage rooms and refrigerated warehouses where maintaining a stable internal temperature is vital.
5. Agricultural Buildings:
• Used in farm buildings, storage facilities, and barns to provide a stable internal environment for livestock or crops.
6. Temporary Structures:
• Ideal for temporary structures or site offices where quick installation and insulation are needed.
 
Installation Considerations:
• Structural Support: Ensure the building framework can support the chosen panel size and weight, though PUF panels are generally lightweight, reducing the structural demands.
• Sealing: Proper sealing at joints is crucial to prevent water ingress and maximize thermal efficiency.
• Roof Slope: Ensure an appropriate roof slope to allow for water drainage and prevent pooling, which can cause damage over time.
