An object of the present application is to provide acoustic and thermal shielding composite materials. An improved acoustic and thermal shielding composite material suitable for use in structures such as buildings, appliances, motor vehicle rooms and exterior parts, having a controlled density and composition. Shielding composites having at least one airlaid fiber layer incorporating the appropriate bonding agents and agents required to meet expectations regarding noise prevention, fire resistance and mold resistance. Separately, an airlaid structure is provided that provides a reduction and suppression of aeration flow useful for soundproofing, including woven or non-woven scrims. [Selection figure] None |
