Patented STC Core Yields High Ratings

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

In February, 2014, the United States Patent and Trademark Office awarded DCI a patent on its proprietary core for STC doors.

The patent is for the unique sound-deadening construction of the door’s core. This construction results in a lighter weight door for the same sound properties. The result is easier installation, and the use of standard hinges.

Before the patented STC core, customers had to weigh the benefit of the STC properties against negatives such as heavier weight, more expensive cam-lift hinges to support the weight, and a core that could rust or harbor mold.

Now you have all the benefits of sound absorption without any of the negatives of a thick, heavy core.

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.

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.

The full line of STC doors and frames are now available from DCI. For further information or to place an order, contact your DCI sales representative or ChuckK@dcihollowmetal.com.
