STC CONCERNS + SOLUTIONS
Over the years, we have experienced various problems when coordinating the finish hardware with sound assemblies, It
is not our intention to change the intended design of the project, but to point out that certain hardware combinations may
compromise the effectiveness, or usefulness of the acoustical product.
In order for Stiles to certify the STC rating of an assembly, it must be fabricated as tested by a certified acoustical
laboratory. Our doors have a factory supplied door bottom, while the frames have a perimeter seal. Neither item is
designed to have hardware, nor any other item attached to it.
Before manufacturing can commence, there must be a review of the hardware schedule to see if any of the following
problems could potentially occur. We have found that the best time to do this review is at the time of submittal / when
shop drawings are prepared. If, during this review, potential problems are discovered, the draftsperson can explain them
in an RFI, outlining possible solutions. A disclaimer on all proposed possible solutions should be included.
Stiles has trained acoustical associates ready to assist you in every manner.
