Selecting the right thickness of EPS Cement Sandwich Panel is one of the most important decisions to ensure your walls meet insulation, soundproofing, and structural performance requirements. On the market, common thickness options for EPS Cement Sandwich Panel range from 60mm, 75mm, 90mm, 120mm, 150mm to 180mm, and each specification is designed for different application scenarios.

For interior non-load-bearing partitions inside residential apartments or office buildings, 75mm to 100mm EPS Cement Sandwich Panel is usually the most cost-effective choice. These thickness levels offer enough sound insulation to separate different rooms, keep wall weight low, and maximize usable indoor space. If you are building exterior walls in areas with cold winters or hot summers, it is better to choose 120mm, 150mm or thicker panels. A thicker EPS Cement Sandwich Panel has a lower thermal conductivity value, which can greatly improve the wall’s overall insulation performance and reduce long-term energy consumption.

For projects that have strict requirements for fire safety and noise control, such as industrial plants, public corridors, and factory partition areas, 150mm or thicker EPS Cement Sandwich Panel will be the ideal option. Before making a final purchase, you should also consider local climate conditions, building energy codes, and specific project needs. Matching the correct panel thickness to your application will help you get the best balance between performance, cost, and long-term durability.
