Sandwich Panel / PU Panel / PIR Panel Description:
1. Sandwich Panel:
Structure: A sandwich panel typically consists of three layers: a low-density core sandwiched between two relatively thin skin layers.
Materials: The core material can be made of different types of foams or other materials, such as polyurethane (PU), polyisocyanurate (PIR), expanded polystyrene (EPS), mineral wool, etc. The skin layers are often made of galvanized steel, aluminum, or other durable materials.
Applications: Used for building walls, roofs, and cladding in commercial, industrial, and residential buildings due to their excellent insulation properties and structural strength.
2. PU (Polyurethane) Panel:
Core Material: The core of a PU panel is made of polyurethane foam, which provides excellent thermal insulation and energy efficiency.
Properties: PU panels have a high thermal resistance (low thermal conductivity), are lightweight, and offer good mechanical strength. They are also moisture-resistant and provide a good barrier against air and water infiltration.
Applications: Commonly used in cold storage, industrial buildings, residential constructions, and other applications where thermal insulation is critical.
3. PIR (Polyisocyanurate) Panel:
Core Material: PIR panels have a core made of polyisocyanurate foam, which is similar to polyurethane but offers improved fire resistance.
Properties: PIR foam has a higher thermal resistance than PU foam, meaning it provides better insulation with a thinner panel. PIR panels are also known for their excellent fire performance, lower smoke emissions, and structural rigidity.
Applications: Ideal for use in environments where fire safety is a concern, such as commercial buildings, industrial facilities, and places requiring high thermal performance and fire resistance.
Common Features of Sandwich Panels:
Insulation: Superior thermal insulation, reducing energy costs for heating and cooling.
Strength: High structural strength while being lightweight, making them easy to install and handle.
Durability: Long-lasting and resistant to various environmental factors such as moisture, temperature changes, and mechanical impacts.
Aesthetic: Available in various finishes and colors, allowing for design flexibility in building facades.
Fire Safety: PIR panels, in particular, offer enhanced fire resistance, meeting stringent safety standards.
Conclusion:
Sandwich panels, including PU and PIR panels, are versatile construction materials widely used for their excellent insulation properties, structural strength, and durability. PU panels are ideal for applications requiring high thermal efficiency, while PIR panels are preferred in scenarios where fire safety is paramount.
