  • Product Description
  • Installation and Technical Information
PDB Automatic Door Bottoms

  • Unique patented design creates uniform seal pressure across the entire door bottom, resulting in superior acoustic performance
  • Use a flat saddle to create a positive sealing surface that ensures maximum acoustic performance
  • United States Patent No. 8,925,250 B2
In order to reduce the transmission of sound, materials are added between the source room and the receiving room. The resulting change in decibel level is the sound transmission loss and is given a Sound Transmission Class (STC) rating. The higher the rating number, the lower the transmission of sound. The STC rating is roughly the decibel reduction a partition can provide. For instance, if a 100 dB noise is reduced to 55 dB, that product roughly has a STC 45 rating.
