STC Performance Levels in Acoustic Doors/Frames
Frequently Asked Questions
What is an STC rating? STC stands for "sound transmission class".
It represents a method of measuring sound transmission loss through a barrier, ie. a door or a wall. The higher the STC rating the better the sound deadening property of the door. Ambico provides 1-3/4" thick doors from STC 33 to STC 53. Doors up to 6" in overall thickness provide a rating of
STC 56. Let us help you select an acoustic product that will meet your
project requirements.
Are acoustic doors supplied with seals and door hardware? Perimeter seals, bottom seals and thresholds are always supplied, as they are integral to the sound deadening properties of the door/frame unit. Heavyweight butt hinges and latching devices are available through Penner Doors & Hardware.
Can acoustic doors be provided with glass lites? Ambico has tested glazed acoustic doors that have achieved STC 52. Glazing material must be factory pre-installed.
