Sandwich panels can be utilised as acoustic panels to assure sound insulation in addition to being used for thermal-humidity insulation and waterproofing. These products offer a strong acoustic performance and sound-absorbing property because to their rock wool insulation layer and perforated surface. The ability to achieve structural efficiency is the primary justification for employing these items. Thick, light-weight cores are firmly fastened to thin, hard, inflexible coverings. Sandwich panels are light and have a relatively high flexural strength despite the thickness of the core. These composites' spatial organisation affects how well they function as thermal insulators.
