Whether it’s band practice or your four-legged family member, sound control insulation puts a barrier between you and any distracting noise.
Unwanted sound in buildings is not only distracting, but it can also impact comfort, privacy, and productivity.
That's why contractors, engineers and architects choose fiberglass insulation to effectively decrease the transfer of sound in residential, commercial and industrial buildings through walls, ceilings or ducts and into the spaces where people live, work and play.
Acoustic insulation comes in a variety of forms to meet your unique application requirements from batts, blankets and rolls to boards, duct liner and pipe insulation.
Knauf Insulation products are the more sustainable solution to absorb sound as most are manufactured with ECOSE ® Technology, Knauf's patented, formaldehyde-free bio-based binder - a smarter alternative to the phenol-formaldehyde (PF) binder traditionally used.
The same features that make fiberglass thermally efficient translate directly to the insulation's ability to absorb and reduce sound levels.
The Sound Transmission Class (STC) is a single number rating used to indicate the effectiveness of an entire construction assembly (partition, wall, floor/ceiling) in resisting the passage of airborne sound. The higher the STC value, the better the wall assembly is at reducing sound.
For residential partition walls, the recommended STC depends on the particular type of room: for example, in bedrooms, an STC of 52 is good. Living rooms, bathrooms and kitchens should be a minimum of 55.9.
In addition to the STC rating which concerns airborne sound, floor/ceiling assemblies are also rated for impact sound resistance. Impact sound is structure-borne sound transmitted when one body strikes another, such as in the case of footsteps and falling objects. A single number, the impact insulation class (IIC), is used to describe impact sound performance. As with STCs, a higher number indicates better performance. The current International Building Code requires a minimum IIC rating of 50.10.
