Differences in thermal insulation performance of EPS sandwich panels of different thicknesses

The thermal insulation performance of EPS (polystyrene) sandwich panels are mainly affected by their thickness and density. Here are some differences in thermal insulation performance of EPS insulation panels of different thicknesses:

Basic principles of thermal insulation performance

The thermal insulation performance is usually measured by "thermal conductivity (λ)", the lower the thermal conductivity, the better the thermal insulation performance. The thermal conductivity of EPS is generally between 0.030-0.040 W/(m·K), and the specific value depends on the density and thickness of the board.

Thermal insulation performance of different thicknesses

30mm thickness:

Thermal resistance (R value) is about 0.63-0.83 m²·K/W

Suitable for light insulation needs, such as interior walls or not too cold environments.

50mm thickness:

Thermal resistance (R value) is about 1.25-1.67 m²·K/W

Suitable for medium insulation needs, such as exterior walls and roofs, and can effectively resist cold climates.

75mm thickness:

Thermal resistance (R value) is about 1.88-2.50 m²·K/W

For buildings that require higher insulation performance, it is suitable for cold areas.

100mm thickness:

Thermal resistance (R value) is about 2.50-3.33 m²·K/W

Provides excellent insulation effect, suitable for applications such as cold storage and refrigerators that require strict temperature control.

150mm thickness:

Thermal resistance (R value) is about 3.75-5.00 m²·K/W

Suitable for extreme climate conditions, provides excellent insulation performance, and is suitable for high-efficiency buildings.

Summary

The greater the thickness, the better the insulation performance: As the thickness of the EPS sandwich panel increases, the thermal resistance value increases and the insulation effect is enhanced.

Choose the right thickness: The appropriate EPS insulation panel thickness should be selected according to the building's geographical location, climate conditions and insulation requirements to achieve the best energy efficiency and comfort.
