Description:

AP435 is the carpet underlayment we recommend to isolate Acoustiblok from a subfloor. This will allow our isolation material, Blok 16 or Blok32, to remain decoupled to reduce structural flanking of sound transmissions. This helps increase the STC of the entire floor assembly. The second advantage can be an increase of IIC, impact isolation from foot fall within a floor/ceiling assembly.
