303_S, 312_R & 315_R Perimeter Gasketing
Acoustic Perimeter Gasketing
Rigid jamb weatherstrip shown mounted on openings with 1/16" gaps; however, each weatherstrip can seal gaps up to the depth of its seal. Seal depth provided on each illustration (example: the 303 has a 1/4" seal; therefore, it can seal up to a 1/4" gap)
- Punched on 6" centres with slotted holes for adjustment
- Model 303 is available with self-adhesive two-sided tape (TST) and tek screws (3 slotted holes per part) for easy installation. To obtain this option, add “TST” to the end of the part when ordering (example: 303AVTST) Pemko is continually commissioning tests for acoustic assemblies.

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.
