Executive Door has tested 1 ¾” raised panel Environmental Doors and fire doors through an independent testing laboratory for their resistance to sound transmission.

Testing was conducted in accordance with ASTM E 90-99.  All tests were conducted on single doors.  The gasketing system surrounding the doors tested included components manufactured by Pemko Manufacturing.  Passage hardware was from Quickset.

Environmental doors tested achieved an STC rating of 30 to 35 with 35 being the highest.

Sound transmission tests are a good barometer of a door product’s resistance to the transmission of sound from one side of the door to the other.  Tests are

conducted under laboratory conditions.  Actual noise levels achieved in residential or commercial installations will be affected by the design of door selected, the hardware selected, the materials surrounding the door and the quality of installation.
