Ever wonder what the stc ratings of doors means and why it s important.
Stc rated solid core wood doors.
Soundproof doors are available at greater thicknesses from stc 51 to stc 56.
Generally a less soundproof door such as a hollow core door is given 20 for an stc rating which means that most conversation level speech will still be heard when the door is closed.
Any unsealed gaps and clearances in door assemblies effectively cancel out the noise reduction benefits of stc rated doors.
For example 1 8 clearances around the edges reduce the effective rating of an stc 52 door to stc 21.
Doors and frames have been tested as a assembly and are supplied with acoustic perimeter and bottom seals.
