Acoustic Rated Doors
Testing of acoustic door frame assemblies by independent laboratories complies with the most up to date standards on the continent.
Acoustic rated doors. Fire rated doors are available up to 90 minutes and may be supplied in singles or pairs. All cdl acoustic doors are tested in this manner. Because acoustical doors are constructed differently than traditional hollow metal doors certain considerations must be made when selecting hardware for them. Acoustic doorsets are available in a range of stc rw ratings from 27 to 47.
For an stc rated door set the door panel surround frame and seal system should be tested as a combination. Our designs also interface with the locks and accessory hardware you have chosen for your project. Acoustic doors an acoustic doorset consists of a door leaf or leaves door frame and seal package that has been tested for acoustic performance to as 1191 1985. When specifying acoustical doors one often overlooked concern is the hardware.
Krieger acoustical doors are delivered as complete performance guaranteed acoustical assemblies with seals hinges and threshold included. Some options work better than others and some do not work at all. The sound performance of the building wall ceiling and floor should also be assessed when selecting an acoustic door set as good performance can be undermined by flanking sound leakage. Additionally cam lift hinges and an aluminum threshold are included with high stc rated assemblies.
Measured by laboratory testing of the door per astm e 90 the results are reported as stc sound transmission class rating affirming the doors ability to meet specific project requirements.
