quarters, home theaters, recording/broadcast studios, sports
facilities, mechanical rooms, etc.. We also offer solutions for isolating
elevators and decoupling structural elements like stairways.
RPG has approached noise and vibration issues with the same fresh
approach and creativity that it used to develop the sound diffusion
industry. Our Noise and Vibration team consists of experienced
mechanical engineers, architects and Ph. D.s, with access to world
class testing and research facilities. Our product line utilizes the
widest range of elastomers, including natural rubber and
polyurethane foams (with the lowest resonant frequencies in the
industry), cork
rubbers, resin-
bonded recycled
car and truck tires
and microcellular
foams. The product
range consists of
traditional and new solutions to vibrational and airborne problems.
We invite you to visit our website and review these products. RPG
offers design assistance, load calculations, selection of appropriate
springs or elastomers and shop drawings. We also offer free Excel
software to predict the airborne transmission loss of our floor
isolators, using the Prognosis Method and free MathCAD software to
predict vibrational transmission loss for machinery on grade or upper
levels, with or without an inertia pad, using Mobilities.

Everything Acoustic!From humble, cottage industry beginnings, RPG pioneered a
continually emerging sound diffusion industry. Its range of products
and services now includes TopAkustik, one of the industry’s leading
absorptive wood systems, and CDM, the industry’s newest, innovative
noise and vibration systems. RPG is unique in the architectural
acoustics industry in that we don’t just offer products. We strive to be
the acoustician’s partner; providing design assistance, free acoustical
testing, research results, reference text books, publications and personal visits. We invite you to visit our booth at ASA, Baltimore, where we
will exhibit the CDM Noise and Vibration System, as well as our subway and surface rail products. This is only the beginning.....

RPG and TopAkustik are proud to be selected to provide our most complex absorptive wood ceiling and custom
suspension system to date in the world’s tallest building. The project was a significant challenge due to the
technical aspects, the size and the prestige. RPG worked very closely on the Chairman’s Suites, which posed
many challenges most of which centered on the fact that there were no right angles or straight edges. The
project consisted of 750 custom, curved, rhombus-shaped panels with all sides of the panel radiused. The
panels were supplied with no further field cutting required, which demanded a high level of communication
and coordination. The perimeter of the complex ceiling array was required to follow the perimeter of the
building facade with a specified reveal. RPG was responsible for coordinating all field measurements and shop
drawings between all parties. To insure all panel perimeter shapes followed the curvature of the facade, RPG
engaged a surveyor to make thousands of measurements from the origin reference point to the perimeter on
three floors. A custom ceiling suspension system was also developed to accommodate the swaying of the
building. The other portion of this project that utilized TopAkustik materials was the Sky Lobby, and it
contained 1,800 pieces of Topperfo-M 16/16/6 with a Wenge veneer. The ceiling consisted of ten different
height levels and all of the 1,800 different elements had to be individually removable. RPG worked with
SOM Architects in Chicago and PMK Consultants to be specified on this project. The main contractor was
Heehoon/Samsung of South Korea and communication was key to a successful installation.
With complex projects like the Burj Khalifa, Dubai, The TimesCenter, NY and Morgan State University
Library (with 2,000 unique sized panels), RPG has established a reputation as a leader in designing and
supplying complex, custom engineered absorptive wood ceiling and suspension systems, using
Topakustik, Topperfo and the new Topperfo Micro (with 30,000 holes/sf) planks and panels . We invite
you to explore the possibilities.
