- Our Factory
- Project Case
The two core materials each have distinct characteristics: polyurethane sandwich panels offer outstanding insulation performance and are relatively lightweight. Rock wool sandwich panels have the highest fire resistance rating and excellent high-temperature resistance. It is recommended that you make a choice after a comprehensive consideration of the specific insulation requirements, fire protection standards, and budget conditions of the project.
The thickness directly affects its thermal insulation performance and strength. For regular walls, a thickness of 50-100mm is commonly used; for roofs, 75mm or more is recommended. We can provide professional selection recommendations based on your building’s purpose, local climate, and energy-efficiency standards.
Sandwich panels (especially those with rock wool cores) have excellent sound insulation performance and are widely used as partition walls in office buildings and dormitories. We also offer composite boards with enhanced sound insulation design to meet your higher requirements.
The fire resistance characteristics of sandwich panels are mainly determined by the core material. We offer a wide range of options, from B1-grade polyurethane/PIR boards to A-grade rock wool boards, that fully meet national building fire protection code requirements.
Standard sandwich panels are not recommended for direct load-bearing. However, we can provide local reinforcing plates or pre-embed special steel-structure connectors in the design to ensure safe load transmission to the main structure.
What is a Sandwich Panel?
Sandwich panels are composed of two layers of metal panels (or other high-strength materials) on the inside and outside, filled with lightweight insulating core materials (such as polyurethane, rock wool, etc.) in the middle, and combined with high-strength adhesives.
It combines the panel’s sturdiness and weather resistance with the core material’s thermal, sound, and fire insulation, and offers the advantages of light weight and quick, flexible installation. It is widely used in industrial plants, logistics warehouses, and commercial buildings.
The Structural Composition of Sandwich Panels
Upper and Lower Panels
- Function: The upper and lower panels provide structural support, protection, and aesthetic decoration, which offer wear resistance and weather resistance.
- Common Materials: The surface panel is typically made of color-coated steel plate (corrosion-resistant and aesthetically pleasing), stainless steel plate (meets the high cleanliness requirements of food, medicine, etc.), aluminum plate (lightweight and corrosion-resistant), etc.
Core Material
- Function: The core material determines the thermal insulation, sound insulation, noise reduction, and fire resistance performance of the board, and significantly reduces the weight of the board.
- Common Materials: Core materials typically include polystyrene foam (low cost, good insulation, lightweight), polyurethane (insulation and fire resistance), rock wool (fireproof and soundproof), etc.
Why is it Necessary to Use Sandwich Panels?
Thermal Insulation and Energy Conservation
The lightweight core materials of Pupanel sandwich panels (such as polyurethane and rock wool) have extremely low thermal conductivity, forming an efficient insulating layer.
Using it as a building material can significantly reduce heat exchange between indoors and outdoors and notably lower energy consumption for heating and cooling. It is an ideal choice for you to reduce long-term operating costs.
