Can You Hear Me Now?

In 2021, Nation’s Roof just completed a studio roof for Lionsgate near Yonkers, NY. Once production began in the studio, the recording engineers identified a serious problem that needed to be solved in the design and construction of the studio. The studio was adjacent to the Yonkers train station with over 100 trains passing daily. The exterior sound levels were so high and that the sound was being picked up by the microphones inside of the studio.

When they were approached with an opportunity again to create another stage building a few blocks away from the original, they knew they had an opportunity to improve the soundproofing. They mobilized a team of manufacturers including Georgia-Pacific, Carlisle, Rockwool, and Beacon to solve the sound problem in the roof assembly itself before installation. The team delivered the client a strong, durable roof with a robust STC rating of 55, that will help keep exterior noise outside, and protect the building envelope.

The Roof Assembly

There are three fundamentals to reducing sound transmission through a roof assembly MASS, ABSORPTION & DECOUPLING.

To keep the unwanted exterior environmental noise outside where it belongs a plan was established with the assistance of ROCKWOOL. The ROCKWOOL Building Science team used the results from their highest performing assembly to model a further improved assembly using INSUL. The resulting STC rating of 55 is a very robust rating which exceeded the client’s demanding requirements
for this challenging site.

Measuring over ten and a half inches deep, the full assembly is an array of roofing products. Together they provide the sound blocking properties required to reduce outside inside sound transmission.
