Increased STC Ratings
Up to STC 54 for Singles and 48 for a Pair of Doors

The STC (Sound Transmission Class) rating process has come a long way over the last 20 years. Today, STC ratings are more accurate and precise than ever.

DCI has developed a number of engineering and manufacturing innovations to increase the STC ratings of its custom hollow metal doors and frames.

Those results have paid off, as recent tests by a certified testing agency confirm that DCI single doors offer a full range to STC 54 for single doors and to STC 48 for pairs of doors.

STC is a number rating of how well a building partition reduces airborne sound. In the U.S., it is widely used to rate doors, windows, floors, ceilings, etc. As technology continues to advance, the ASTM test methods tend to change every few years. Therefore, a door tested 15 years ago will unlikely attain the same STC rating were it re-tested today.

With these new test results, DCI combines the highest STC ratings with the fastest delivery of STC doors of any hollow metal door manufacturer.

How can we manufacture such highly-rated STC doors in two weeks or less? The answer is that for the past 30 years DCI has been a “quick ship” hollow metal door and frame manufacturer, thanks to the streamlined manufacturing of all products under one roof and focus on disciplined processes and a skilled workforce. Our internal design specification for the new top-rated STC doors allowed the doors to be made in two weeks or less.
