Thermal Insulation Performance: The thermal insulation performance is 2.7 kcal/m²/h/℃, and the thermal conductivity is 0.12 W/m·K. The low thermal conductivity indicates that the panel has good thermal insulation properties, effectively preventing heat transfer and reducing heat exchange between indoors and outdoors, thereby reducing energy consumption. It is suitable for places requiring constant temperature, such as laboratories and cleanrooms.
Sound Insulation Performance: The sound insulation performance is 18 dB. Thicker panels can achieve better sound insulation and noise reduction; for example, 100mm thick panels offer better sound insulation. Perforated sound-absorbing panels can also be made by punching holes (3mm diameter, 5mm spacing) on the steel plate surface, with non-woven fabric filling between the steel plate and rock wool to prevent rock wool leakage and further improve sound insulation. Sound insulation performance is related to the density of the internal core material. Generally, a higher density core material results in better sound insulation, but the noise reduction effect may vary. If using sound-absorbing panels, rock wool with a density of 80-100 is recommended. For single-panel roof structures, a structure combining noise-reducing mesh and glass wool is typically used.
