Sound resistant doors

We express sound insulation in three values.


  • Rw value = sound insulation of the doorset in fully sealed situation.

  • Rw, p value= sound insulation of the doorset in suspended situation, tested in a laboratory.

  • Rw, r value= sound insulation of the doorset in suspended situation on site.

the latter value is ca. 3-4 dB lower than the Rw,p value due to irregularities on site.
