In Marcus Hiles’ 15,000 upmarket residences throughout Texas, cellulose sound insulation gives tenants their own hideaway from the outside world. While the properties exhibit the developer’s dream of community-centric features, including shared recreation centers and championship golf courses, Hiles respects the need for residents’ private home life—one without any audible interference from the community outside or even just next door. Full depth cellulose is eignificantly effective in its mission to prevent intrusive sound. While general 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. Roughly three times more dense than standard fiberglass, this insulation is nothing short of a major improvement over many common types of home insulation.
