Noise is a bigger issue than ever as buildings become more densely populated,, more multi-purpose, and more reliant on shared infrastructure. In 2026, we see this most clearly in the rise of mixed-use buildings, hard-surface flooring, tighter mechanical chases, and an increasing number of retrofit projects. Add more people working from home, and sound issues that were once tolerated now directly affect comfort, privacy, and productivity.
Most noise problems fall into three main categories. Airborne noise includes voices, televisions, music, and traffic. Impact noise comes from footsteps, dropped objects, and furniture movement between floors. Mechanical or equipment noise originates from plumbing stacks, HVAC systems, pumps, and generators.
Choosing the right soundproofing material is dependent on the location of the noise issue and the end goal. There is no single magic product. Effective noise control comes from using the right materials in the right locations, as part of a complete wall, floor, ceiling, or enclosure assembly that accounts for structure, sealing, and flanking paths.
Before looking at specific products, it helps to understand how the main types of soundproofing materials work.
A Quick Framework: How Soundproofing Materials Actually Work
Where Each Material Type Lives in a Building
Cavity insulation, such as Quiet Batt®, is installed inside walls and ceilings to absorb sound energy and support improved transmission loss.
Underlayments, such as Impact Barrier® QT, sit beneath finished flooring to reduce impact noise traveling through the structure.
Wraps, such as Quiet Wrap™, are applied directly around pipes and ducts to reduce the noise that transfers into nearby rooms.
Composite panels, such as Quiet Barrier® Specialty Composite, are surface-mounted treatments used for high-noise equipment and enclosures where rebuilding walls is not practical.
Barrier materials, including Quiet Barrier® HD, add dense, flexible mass to walls, ceilings, floors, and enclosures to reduce sound transfer.
Quiet Batt®: High-Performance Insulation for Walls and Ceilings
What Quiet Batt® Is and How It Performs
Quiet Batt® is a 3-inch-thick, R-13 recycled cotton insulation designed for use in interior and exterior walls, ceilings, and drop ceilings. It is manufactured with roughly 80 percent recycled natural cotton fibers.
With an NRC of 0.95 under laboratory test conditions, Quiet Batt® is highly effective at absorbing sound energy. It also carries a Class A flammability rating, which matters when code requirements limit exposed or semi-exposed materials.
Quiet Batt® will not soundproof a wall by itself. Absorption alone does not stop sound from passing between rooms. Instead, Quiet Batt® supports soundproofing by reducing sound energy so that barrier layers, sealing, and decoupling measures can work more effectively.
Best Uses for Quiet Batt® in 2026 Projects
Quiet Batt® is commonly used in interior partitions where speech privacy is important, including bedrooms, home offices, counseling rooms, conference rooms, and classrooms. It is also used in ceiling and floor cavities in multifamily, hospitality, and office buildings as part of upgraded acoustic assemblies. For higher-performing wall systems, it is often paired with barrier materials like Quiet Barrier® HD and, where appropriate, isolation clips or channels.

Impact Barrier® QT: Underlayment for Footfall and Impact Noise
What Impact Barrier® QT Is
Impact Barrier® QT is a flat, resilient underlayment made from 92 percent recycled SBR tire rubber. It is designed to be installed directly under a wide range of floor finishes, including carpet, tile, stone, hardwood, laminate, and other hard surfaces.
It is engineered specifically for impact sound insulation and has been tested in hundreds of laboratory and field assemblies to quantify improvements in Impact Insulation Class.
Where Impact Barrier® QT Makes the Most Difference
Impact Barrier® QT is widely used in multifamily housing, condominiums, and high-rise buildings where upstairs walking, chair movement, and dropped objects are common complaints. It is also used in hotels and hospitality projects where footfall control is critical to the guest experience. In mixed-use buildings, it helps manage impact noise without limiting design freedom in floor finishes.
It is important to note that impact noise performance depends heavily on the overall floor and ceiling structure. Underlayment alone cannot overcome poor framing, direct mechanical coupling, or structural shortcuts. Impact Barrier® QT performs best as part of a properly designed floor-ceiling assembly that includes perimeter isolation and adequate cavity treatment below.

Quiet Wrap™: Pipe and Duct Wrap for Plumbing and HVAC Noise
What Quiet Wrap™ Is
Quiet Wrap™ is a pipe and duct soundproofing wrap built from a mass loaded vinyl barrier layered with acoustic polyurethane foam. It is supplied in rolls with a pressure-sensitive adhesive backing for direct application.
The barrier layer blocks radiated pipe noise, while the foam layer absorbs and damps sound energy generated by turbulent flow, fittings, and vibration. Quiet Wrap™ is rated for use in conditions up to approximately 140°F and features a foam component with a UL 94 HF-1 flammability rating, with the standard requirement that codes be checked for each application.
Why Pipe and Duct Noise Need Their Own Solution
Plumbing and HVAC noise is best addressed at the source. Wastewater and drainage pipes generate a mix of low-frequency rumble and higher-frequency splashing, while HVAC ducts can carry fan noise and vibration throughout a building envelope. Simply adding more wall insulation does not interrupt these vibration paths. Wrapping the pipe or duct directly is often the most efficient and predictable solution.
Best Uses for Quiet Wrap™
Quiet Wrap™ is commonly used on noisy plumbing in multifamily, hospitality, and office buildings, as well as on noisy supply and return ducts near sensitive spaces. It is particularly effective in retrofit projects where walls are open and pipes and ducts are accessible.

Quiet Barrier® Specialty Composite: Four-Layer Control for High-Noise Sources
What Quiet Barrier® Specialty Composite Is
Quiet Barrier® Specialty Composite is a four-layer acoustic composite designed to combine absorption, blocking, and decoupling in a single product. It consists of a reinforced polyester film facing, a thick acoustic foam absorption layer, a Quiet Barrier® mass loaded vinyl layer, and a thinner foam backing that helps decouple the panel from the mounting surface.
Product data lists an STC of 24 and an NRC of 0.70, with an overall thickness of approximately 1 5/16 inches and coverage of 18 square feet per sheet.
This product is designed to supplement, not replace, structural soundproofing. It is not a substitute for rebuilding walls where significant low-frequency isolation is required, but it can be highly effective where surface-mounted treatment is the only practical option.
Where Quiet Barrier® Specialty Composite Is a Good Fit
Quiet Barrier® Specialty Composite is commonly used in mechanical and equipment rooms housing compressors, pumps, small generators, and HVAC cabinets. It is also used to line equipment enclosures and panels in industrial, marine, and automotive settings where both sound reduction and limited heat resistance are needed. It is especially useful when wall reconstruction is not feasible but lining an enclosure or cabinet interior is possible.

Quiet Barrier® HD: Heavy-Duty Mass Loaded Vinyl for Walls, Ceilings, and Enclosures
What Quiet Barrier® HD Is
Quiet Barrier® HD is a heavy-duty mass loaded vinyl sound barrier supplied in sheets or rolls. It is 1/4 inch thick and weighs 2 pounds per square foot, combining significant mass with flexibility for installation over framing or existing surfaces.
When used as part of a properly detailed assembly, Quiet Barrier® HD is designed to block airborne sound transmission. Like all barrier materials, its effectiveness depends on airtight installation. Seams, penetrations, edges, and interfaces must be properly sealed to avoid performance loss.
Best Uses for Quiet Barrier® HD
Quiet Barrier® HD is commonly used to upgrade party walls, office walls, and other partitions where more isolation is needed than standard gypsum and insulation can provide. It is also used in high-output rooms such as home theaters, small studios, and music practice spaces, particularly when combined with Quiet Batt® and decoupling elements. In addition, it is used to line or wrap small enclosures for noisy devices when properly supported.
