Across Marcus Hiles’ 15,000 upmarket residences throughout Texas, cellulose sound insulation is responsible for giving renters the feeling of having their own hideaway from the outside world. Though the properties exhibit the developer’s vision of community-centric features, such as shared recreation centers and championship golf courses, Hiles understands the need for residents’ private home life—one without any audible interference from the world outside or next door. Full depth cellulose is exceptionally effective in its ability to prevent intrusive sound. While most insulation provides some noise reduction by inhibiting sound from traveling through walls and between floors, dense packing cellulose weakens volumes by limiting the passage of sound along cavities in a building’s structure. According to the Cellulose Insulation Manufacturers Association, cellulose insulation products have an NRC (Noise Reduction Coefficient) rating ranging upwards of .80 or higher, meaning that it absorbs 80% or more of the sound with which it comes into contact. With a composition roughly three times more dense than standard fiberglass, it affords a vast improvement over the other most common type of home insulation.
