While siding alone cannot guarantee a perfectly soundproof house, it can significantly reduce unwanted noise. The right combination of siding material, insulation, and installation techniques can help create a quieter home environment. Siding acts as a barrier that slows down the transfer of sound waves into a home, with thicker, denser materials or those paired with quality insulation tending to perform best. High-density materials such as stucco, brick, or fiber cement are popular choices for sound insulation, while insulated vinyl siding is also known to reduce noise by up to 39%.

What You'll Learn
Insulated vinyl siding
The effectiveness of insulated vinyl siding in reducing noise has been demonstrated through testimonials and third-party laboratory tests. Homeowners with insulated vinyl siding have reported that their homes became noticeably quieter, with a reduction in noise from sources such as street traffic, barking dogs, and thunderstorms. Laboratory tests have also confirmed that insulated vinyl siding can reduce noise transmission by up to 39% compared to a base wall, performing significantly better than other materials like fiber cement.
The sound-insulating properties of vinyl siding are due in part to its contoured, rigid foam backing, which is permanently adhered to the vinyl siding. This foam backing provides a long-lasting appearance, energy savings, and improved impact resistance compared to traditional vinyl siding. Additionally, the thickness and weight of the siding also play a role in its ability to dampen sound. Heavier and thicker materials tend to be more effective at blocking sound transmission.
While insulated vinyl siding can provide sound insulation, it is important to note that it may not be the most effective solution for soundproofing. Materials with more mass, such as stucco or brick, are often better at blocking sound. Additionally, proper sealing of windows and other potential air leaks is crucial, as sound can travel through these openings. Combining insulated vinyl siding with other sound-absorbing materials and sealing any gaps can help optimize the sound insulation of your home.
There are also other insulated sidings available in the market, such as the Charter Oak® Energy Elite, which features a contoured foam underlayment, and the Caliber High Performance Insulated Siding by Georgia-Pacific, which offers superior durability and energy efficiency.

Soundproofing with landscaping
While siding can act as a sound barrier, it is not always the most effective method for soundproofing. The addition of insulation and the choice of dense materials can improve its soundproofing capabilities. However, for a comprehensive approach to soundproofing, landscaping techniques should also be considered.
Landscaping for soundproofing involves using a combination of natural and built elements to block, absorb, and deflect sound waves. Here are some strategies to consider:
Plantings
Trees, shrubs, and hedges can be effective sound barriers in landscapes. Evergreen trees with dense branches and thick, lush leaves are particularly good at absorbing sound waves. The closer these plantings are to the source of the noise, the better their sound-blocking effects. When selecting trees, consider their mature size to ensure they will provide ample coverage. Native shrub varieties are also recommended for low-maintenance noise cancellation.
Walls and Fences
Constructing a wall or fence can provide a quick and effective solution to block sound waves. Masonry walls, for example, can reflect sound back towards the source. For a more aesthetically pleasing option, consider a decorative wood fence. Sound-absorbing materials can also be added to one side of the wall or fence to maximize noise absorption.
Water Features
Water features, such as fountains, can be used to create white noise, which helps to mask undesirable sounds. The sound of rushing water can be particularly effective during loud times of the day, such as rush hour. In quieter times, the fountain's sound can be dialled down to a more subtle level.
Speakers
Installing speakers in your landscape can allow you to play music or nature sounds to drown out unwanted noise. Speakers that blend in with the natural environment, such as those disguised as boulders, can be strategically placed in your backyard. Remember to be considerate of your neighbours when using speakers to avoid creating a noise disturbance for them.
Combinations
For the best results, combine multiple soundproofing techniques. For example, you can build a fence and plant trees and shrubs in front of it, creating a natural barrier that blends in with your landscape. Additionally, consider using sound-absorbing materials on hard surfaces, such as walls, to prevent sound reflection.

Denser materials
Sound waves cause vibrations when they strike dense materials, and this vibration passes energy through the materials' rigidity. This is known as flanking transmission noise. Dense materials with open cells, such as QuietFibre Stone Wool Cavity Insulation, can absorb sound energy and prevent amplification in empty cavities.
Polyester fibre is another dense material with a unique blend of heavy density (approximately 2000g/m^3) and porosity. Its sound absorption increases with the frequency of the sound, making it most effective at high frequencies.
For siding, thicker and denser materials perform best at blocking sound. Dense options include fibre cement or thick wood. Stucco or brick are also good options for siding, as they have a lot of mass.
Insulated vinyl siding is another option that can reduce noise by up to 39% compared to a base wall. This siding has a foam backing that adds density and helps absorb sound.

Installation techniques
Work with a Certified Installer: Employing a certified installer ensures that your siding is properly fitted and secured for optimal soundproofing. They have the expertise to identify and address potential entry points for noise, such as gaps or weak spots. A professional installer will ensure tight fits and maximise noise reduction by knowing where and how much insulation to use.
Choose the Right Siding Material: Opt for thicker, denser materials like fibre cement, stucco, or brick. These materials inherently block noise more effectively due to their mass. Vinyl siding, while less dense, can be paired with foam backing to improve its sound-dampening capabilities significantly. Wood siding provides moderate soundproofing and can be enhanced with insulation.
Add Insulation Layers: Consider adding a second layer of insulation, such as foam, fibreglass, or mineral wool, behind your siding. This extra barrier not only improves energy efficiency but also helps to dampen sound by absorbing it before it reaches your interior walls.
Seal Gaps and Cracks: Gaps and cracks in siding can easily allow sound to penetrate your home. Use caulk and weatherstripping around windows, doors, and seams to block sound effectively. Repair any cracks or holes promptly. Additionally, ensure that your windows are properly sealed and consider double-paned windows to reduce sound transmission.
Consider Decoupling Techniques: Investigate decoupling techniques to reduce sound transmission from the exterior to the interior. "Resilient channel" is an example of a decoupling option that can be combined with other deadening techniques to significantly reduce sound infiltration.
Strategic Landscaping: While not directly related to siding installation, strategic landscaping can redirect or diffuse noise before it reaches your walls. Trees, shrubs, and privacy fences act as sound barriers, providing an additional layer of defence against unwanted noise.

Soundproofing windows
One way to soundproof windows is to install a second window behind the existing one. This second window is placed within the interior sill framing of the existing window and can be opened for ventilation. These soundproof windows are made of two sliding panes of heavy laminated glass, creating a cavity of space between the outer and inner panes. This cavity, along with the mass of the glass, helps to block sound transmission.
Another option is to use window inserts, which can be placed within the existing window frame. These inserts are typically made of heavy, laminated glass, similar to the soundproof windows. This option is particularly useful if you already have double-pane windows, as there are limited additional soundproofing measures that can be taken.
There are also some simpler, more cost-effective methods to improve the soundproofing of your windows. One such method is to use adhesive-backed foam insulation tape to seal the gaps where the window slides on tracks. This helps to block sound transmission by filling in the gaps that sound can travel through. Another similar method is to use weather stripping or caulk to seal around the windows, doors, and seams. This creates an air barrier that can help reduce sound leakage.
Additionally, you can combine soundproofing windows with other noise-reducing measures such as installing dense siding, using thick curtains or blinds, or even creating a barrier with landscaping, such as trees or shrubs, to help redirect or diffuse noise before it reaches your windows.
By implementing these strategies, you can significantly reduce unwanted noise and create a peaceful and quiet environment in your home or office.
