glass wool sandwich panel

The sound insulation and heat insulation performance of the insulated panels are significantly different from the different core material. The following four common types of EPS insulated panels, PU/PIR insulated panel, glass wool insulated panel and rock wool insulated panel are explained:   Property PU/PIR  Panel Rock wool/mineral wool Panel Glass Wool Panel EPS Panel Thermal Conductivity 0.022~0.024W/m·k 0.035~0.045W/m·k 0.03~0.04W/m·k 0.03~0.04W/m·k Density Low(36~43kg/m³) High(100~150kg/m³) Low(10~50kg/m³) Low(8~20kg/m³) Fire Resistance Moderate Excellent Excellent Poor Moisture Resistance High High Low Moderate Acoustic Performance Moderate Excellent Good Poor Cost  High Moderate Low Low   From the above table, the PU/PIR insulated panel has the lowest thermal conductivity and the best thermal insulation performance, followed by EPS. Because of its unique fiber structure, rock wool insulated panel has the best sound insulation effect, followed by glass wool. The EPS insulated panel has the highest cost performance. Users can choose according to different purposes.
