DCI Awarded Patent for STC Door Core
Lighter weight offers many benefits

February 5, 2014 FONTANA CA ― The United States Patent and Trademark Office has 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.

Another feature is that the patented core is made of galvannealed steel. This is the same steel material that is used in Door Component’s standard door construction. Because the core is galvannealed, there is no risk of rust or mold.

Chuck Kiley, Vice President of Sales and Marketing for DCI, said “Before our 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.”
The STC door with its new patented core is now available.
