This Alexandria, VA customer suffered from a noisy neighbor who kept him awake at night. He needed a way to reduce the noise coming through the adjoining wall.
Comfenergy used high density sound reducing matting, Rockwool, and sound putty in the construction of a secondary wall in order to reduce sound transmission through the orginal wall. We used the principals of increasing the density and mass of the dividing wall, along with trying to reduce any transmission of vibration caused by sound waves to increase the STC (sound transmission coefficient) of the wall separating the two units.
The results are reduced sound transmission and a quieter environment for our customer.
