Wilhams PUNF acoustic foam with an S-V1 coating is employed where a resistance to fluids and chemicals is required. Ideal for clean room and computer room
applications where a dust free environment is specified. Where Wilhams PUNF acoustic foam is used for internal and external duct linings, the S-V1 surface
treatment provides an effective barrier to water especially at ductwork inlet sections. S-V1 is applied to Wilhams PUNF acoustic foam for engine room applications such as under bonnets and in engine compartments.
