Homeowners often associate insulation with energy efficiency and temperature regulation, but it also plays an important role in promoting tranquility. Attic insulation is a key element in dampening external noises and reducing the transmission of sound between floors. It is important to select the right insulation for sound reduction and to ensure proper installation for maximum benefits.
The NRC (Noise Reduction Coefficient) rating system is used to evaluate the ability of insulation materials to prevent the flow of sound waves. The higher the NRC rating, the more effective the material is at preventing the transfer of sound. It is important to understand how NRC ratings are calculated in order to interpret them accurately when choosing attic insulation for noise reduction.
Attic Insulation for Noise Reduction
Crawlspace encapsulation is a common source of sound leaks due to HVAC systems, plumbing and external sounds like traffic or neighborhood activities. Without adequate attic insulation, these sound sources can easily travel down to living spaces below, disturbing the occupants’ tranquility and distracting them from work or leisure activities. Insulation in the attic creates a barrier and stops these waves from passing through, resulting in significant noise reduction in living areas below.
Spray foam insulation and cellulose are popular attic insulation options for sound control. Spray foam expands upon application, sealing nooks and crannies that can allow sound to pass through. These materials both have impressive acoustic properties and offer varying R-values. Other acoustic options include mineral wool, which is made from recycled paper and is resistant to fire and pests; and fiberglass insulation, which is lightweight, inexpensive and offers good R-values.
