Composition and Structure of PIR Sandwich Panels
Materials Used in PIR Sandwich Panels
PIR Foam Core and Its Properties
The middle part of a PIR sandwich panel is PIR foam. This foam is great at keeping heat in or out and stopping fires. PIR foam is better than PUR foam because it handles heat better. When it burns, it makes a layer that slows fire and smoke. Its tiny closed cells keep water out, making it strong and waterproof. These features make PIR foam perfect for buildings needing top insulation.
Outer Layers: Metal, Plastic, or Other Materials
The outside layers of PIR panels are tough materials like metal or plastic. These layers protect the foam and make the panel strong. Metals like steel or aluminum are often used because they last long and resist weather. Sometimes, plastic is used for lighter or wetter places. Together, these materials keep the panels strong in different conditions.
How PIR Sandwich Panels Are Manufactured
Continuous Production Process
Making PIR panels uses a fast and steady process. This way, all panels are made the same and in large amounts. First, PIR foam parts are mixed and put between the outer layers. Special machines help make the panels better at keeping heat and stopping fires. Factories in places like Italy and Germany use advanced tools to make panels quickly and meet customer needs.
Bonding of Layers and Role of PIR Foam
Sticking the layers together is very important for strong panels. Glue is used to attach the foam to the outer layers, making them stick well. The PIR foam not only keeps heat in or out but also makes the panel strong and able to hold weight. This mix of materials and methods makes panels light, strong, and good for walls, roofs, and inside spaces.
Key Properties of PIR Sandwich Panels
Fire Resistance of PIR Sandwich Panels
Performance under Fire Conditions
PIR sandwich panels are great at resisting fire. They are safe for places needing fire protection. Their special structure stops flames from spreading quickly. Tests like façade and studs bolt tests prove their fire safety. These panels handle high heat and reduce heat transfer. This makes them a top choice for fire-safe buildings.
Reduced Combustibility Compared to Other Materials
PIR foam burns less easily because of its unique makeup. When it meets fire, it creates a char layer. This layer slows flames and smoke. This makes PIR foam safer than many other materials. It works well for homes and business buildings.
Thermal Insulation in PIR Sandwich Panels
Low Thermal Conductivity of PIR Foam
PIR foam keeps heat in or out very well. It has low thermal conductivity, between 0.022 and 0.023 W/mK. The table below shows how it compares to other materials:
Material | Thermal Conductivity (W m-1 K-1) |
|---|---|
PIR Foam | 0.022–0.023 |
EPS | 30% higher than PIR |
Aerogel | Similar to PIR, one type 8% lower |
This low conductivity helps keep indoor spaces comfortable.
Energy Efficiency Benefits
PIR panels save energy by reducing heat loss or gain. They lower the need for heating or cooling. This cuts down on energy bills. Their thin design also saves space in buildings. This makes them a smart choice for modern construction.
Water Resistance and Durability
Protection Against Moisture and Humidity
PIR panels block water because of their closed-cell design. This keeps them safe from moisture and dampness. They work well in roofs, walls, and cold storage areas. They stay strong even in wet conditions.
Longevity in Various Environments
PIR panels last a long time in different climates. They resist damage and extreme weather. This means fewer replacements are needed. They are a cost-effective and eco-friendly building material.

Comparison of PIR Sandwich Panels with PU Panels
Fire Resistance: PIR vs. PU Panels
Better Fire Safety with PIR
PIR panels are safer than PU panels in fires. They have a B1 fire rating, showing great fire resistance. PU panels usually have B2 or B3 ratings, which are less safe. PIR foam creates a protective layer when it burns. This layer slows flames and reduces smoke, making PIR panels safer. PU panels burn faster and make more smoke because of their materials.
Safer Buildings with PIR Panels
PIR panels are better for buildings needing fire protection. They burn less and make less smoke, keeping people safer. PU panels insulate well but are riskier in fires. Using PIR panels meets fire safety rules and lowers dangers in buildings.
Thermal Performance: PIR vs. PU Panels
PIR Panels Insulate Better
PIR panels keep heat in or out better than PU panels. Their special structure stays strong at high temperatures. PU panels work well but can fail in extreme heat. PIR panels are more reliable for steady insulation.
Best Uses for PIR Panels
PIR panels are great for places needing top insulation and fire safety. They are used in cold storage, warehouses, and energy-saving buildings. PU panels are fine for basic insulation but not for high heat or strict fire rules. For safer and efficient projects, PIR panels are the best choice.
