Are you tired of the constant noise from traffic, barking dogs, or loud conversations from the neighbors? If you are looking for a sound reduction fence, you should compare different types available. The material, construction, height, placement, and number of gaps can all affect how much sound passes through it. In this blog, we compare aluminum, cedar, and concrete fencing with our NORTHERNLINE® vinyl to help you decide which material makes the most sense for your property and budget.
What Is an STC Rating?
Sound Transmission Class (STC) measures how effectively a material limits airborne sound. A higher rating means less sound can pass through, making STC useful when comparing sound reduction fence options.
However, an STC rating does not predict exactly how quiet your yard will become. Results depend on the type of noise, fence height and location, surrounding terrain, and any gaps in the fence line. Low-frequency sounds, such as truck engines, construction equipment, and bass, are also harder to reduce, and sound can still travel over, beneath, or around the fence.
This is why a fence should be described as sound-reducing rather than soundproof.
Comparing the Sound Ratings of Common Fencing Materials
The following approximate STC ratings provide a general comparison of four common fencing materials:
- Aluminum fencing – STC 20 – Durable and attractive, but generally provides the least sound control of these four materials
- Cedar fencing – STC 23 – Provides some sound reduction, but aging boards can develop openings over time
- Vinyl fencing – STC 26 – Provides better sound control than aluminum and cedar while remaining practical for residential properties
- Concrete fencing – STC 37 – Provides the strongest sound control but is more expensive and can be complicated to install
These numbers should be treated as approximate comparisons. The exact performance of any fence depends on its particular design, thickness, construction, installation, and condition.
Is Concrete the Best Fence for Sound Control?
With an approximate STC rating of 37, concrete provides the strongest sound control of the materials compared. However, it is heavier, more complicated to transport and install, and may require substantial foundations, specialized equipment, and additional site preparation.
Concrete fencing can also cost up to three times as much as vinyl fencing of the same height. This may be worthwhile beside a highway, industrial operation, or other major noise source, but it can be difficult to justify for ordinary residential noise.
Why Is Our NORTHERNLINE® Vinyl a Strong Choice for Sound Reduction?
Our NORTHERNLINE® full-privacy vinyl fencing has an approximate STC rating of 26. This makes it a strong sound reduction fence for homeowners who want better sound control than standard aluminum or cedar without the cost and complexity of concrete.
The tongue-and-groove vinyl boards fit tightly together to form a continuous privacy panel. Unlike picket or other open fence styles, the panel does not have intentional spaces throughout the fence line for sound to pass through. Vinyl boards also do not rot, shrink, or warp like wood, helping the panels remain solid and consistently fitted as the fence ages.
This makes our NORTHERNLINE® vinyl a particularly strong choice for homeowners who want several benefits from the same fence:
- Better sound control than standard aluminum and cedar fencing
- Full visual privacy between neighboring properties
- A clean and consistent appearance
- Very little ongoing maintenance
- Long-term resistance to moisture, rot, and insects
- A more budget-friendly alternative to concrete fencing
NORTHERNLINE® vinyl is not a complete soundproofing system. However, it can help soften common outdoor sounds while creating a more private and comfortable backyard.
What Makes a Fence More Effective at Reducing Sound?
The fencing material is important, but the design and installation also affect the final result. An effective sound reduction fence should be solid, tall enough to block the direct line of sight to the noise source, and installed with as few openings as reasonably possible.
For the best practical performance, consider the following:
Choose Full-Privacy Panels
Picket, ranch rail, and semi-private fencing allow air and sound to pass through their openings. A full-privacy design creates a more complete barrier.
Limit Gaps Beneath the Fence
Large openings beneath the panels can allow sound to travel through the fence line. Changes in grade should be considered when planning the installation.
Consider the Fence Height
A taller fence can interrupt the direct path between the noise source and the area you want to protect. Local bylaws and property requirements will determine the height permitted on your property.
Consider Where the Noise Comes From
A fence generally provides the greatest benefit when it blocks the line of sight between the noise source and the person hearing it. The layout of the property, elevation changes, gates, and openings at the ends of the fence can all influence the outcome.
Which Fencing Material Is Right for You?
The best option depends on the severity of the noise, your expectations, and your budget. If maximum sound control is the main priority and the higher cost is manageable, concrete is the strongest choice. It may be particularly worthwhile for a property affected by significant or continuous noise.
For homeowners who want to soften ordinary residential noise without paying the much higher cost of concrete, our NORTHERNLINE® vinyl provides a strong middle ground. As a practical sound reduction fence, its approximate STC rating of 26, solid tongue-and-groove construction, low maintenance requirements, and full-privacy design create a useful balance of sound control and long-term value.
