2. Laminated Glass Window Inserts

Laminated glass window inserts are an excellent option for those looking to enhance soundproofing without replacing their existing windows. These inserts offer the following benefits:

• Constructed of laminated glass, which consists of two layers of glass with a plastic layer in between that effectively reduces vibration

• Provides improved noise reduction

• Increases energy efficiency

Installing laminated glass window inserts can provide these advantages and more.

Laminated glass window inserts can be particularly beneficial for homeowners living in busy urban areas or near sources of loud noise, such as airports or train stations.

By incorporating this soundproofing solution into your existing windows, you can significantly decrease the amount of noise that enters your home and create a more peaceful living environment.

3. Double-Pane or Triple-Pane Windows

Double-pane and triple-pane windows are another effective soundproofing solution, offering varying degrees of noise reduction depending on their construction and materials.

Double-pane windows, which consist of two panes of glass per window separated by a spacer material, have an STC rating of 28-34 and can be more cost-effective than other solutions.

Triple-pane windows, on the other hand, provide even greater soundproofing capabilities compared to double glazed windows. However, single pane windows and external storm windows may come with a higher price tag, especially when replacing an existing window.

Weighing the costs and benefits of double-pane and triple-pane windows is a vital step when choosing a soundproofing solution for your home.

Here are some factors to consider.

• Double-pane windows may offer a more affordable option.

• Triple-pane soundproof windows can provide superior noise reduction and energy efficiency.

• Triple-pane soundproof windows are an attractive option for homeowners with higher noise pollution concerns.

4. Noise-Blocking Window Treatments

In addition to specialized window products, noise reducing curtains and other noise-blocking window treatments, such as blinds and shades, can also help reduce noise pollution and improve the overall comfort of your living space.

These window treatments are designed to block sound and light, making them an ideal solution for bedrooms and other areas intended for rest and relaxation.

Choosing noise-blocking window treatments requires consideration of factors like the thickness and material of the curtains or blinds, and their capacity to absorb sound and block light.

By choosing the right window treatment for your home, you can effectively reduce noise pollution and create a more comfortable living environment.

5. Weatherstripping

Weatherstripping is a simple and cost-effective method for sealing air gaps around windows and reducing noise infiltration.

By applying weatherstripping to the window frame, you can create a secure seal that effectively blocks outside noise from entering your home. To apply weatherstripping, follow these steps:

• Accurately measure the gap around the window.

• Choose the appropriate type of weatherstripping for the job.

• Clean the window frame thoroughly before applying the weatherstripping.

• Cut the weatherstripping to the correct length.

• Apply the weatherstripping to the window frame, ensuring a firm and even application.

Despite being an effective solution for reducing noise pollution, weatherstripping might not be compatible with all window types and materials.

Additionally, proper installation and maintenance are crucial factors in ensuring the longevity and effectiveness of weatherstripped windows.

6. Window Foam Panels

Window foam panels are another affordable, yet less effective soundproofing solution for windows. These panels are made from foam insulation and can be easily applied to the window frame to reduce noise and improve insulation.

While window foam panels can provide some noise reduction and increased energy efficiency, they may not be suitable for loud, deep sounds or for all window types and materials.

To use window foam panels, follow these steps:

• Accurately measure the window frame before purchasing the panels.
• Ensure the panels are applied correctly and securely to the window frame.
• Consult the manufacturer’s instructions for proper installation and maintenance to achieve the best results.

7. Mass Loaded Vinyl (MLV)

Mass Loaded Vinyl (MLV) is a versatile and efficient soundproofing material for windows, made from PVC and vinyl with a heavy material such as barium sulphate or calcium carbonate.

MLV can be hung over windows, similar to a set of heavy curtains, to provide effective soundproofing by reducing the impact of noises such as engines, drums, and other vibrations.

While MLV can be an effective soundproofing solution, it is important to note that it may not be suitable for all window types and materials.

Additionally, proper installation and maintenance are essential factors in ensuring the longevity and effectiveness of MLV.

8. Hang Sound Dampening Curtains

Sound dampening curtains (also called soundproof curtains) are often made from thick, plush fabric that not only blocks noise but also helps insulate your windows, potentially reducing energy costs.

They are also versatile and come in a variety of styles and colors, allowing you to choose curtains that match your home decor while also providing soundproofing benefits.

Installing sound dampening curtains is as easy as hanging regular curtains and a great way to soundproof windows cheaply.

The key is to ensure that the curtains cover the entire window and extend several inches beyond the window frame on all sides. This allows the curtains to effectively block noise from entering around the edges of the window.

Keep in mind that while sound dampening curtains can significantly reduce noise pollution, they may not be as effective at blocking high-frequency sounds as other soundproofing solutions.

Nevertheless, they are a great starting point for anyone looking to improve their home’s soundproofing without making a significant investment.

9. Window Plug

This is by far the simplest answer to the problem of outside noise. Window plugs are easy to build, are made from inexpensive materials, and are highly effective at sound absorption.

They work by filling in the space in front of your windows with layers of acoustic foam, soundproof matting, and wood. The foam at the front absorbs incoming sound waves.

Any noise that makes it through the acoustic foam is blocked by the mat and the wood backer board. Handles are added to the back surface of the wood to allow easy installation and removal.

Plugs have the advantage that they aren’t permanent. They can be added when needed and pull out when not. And that’s good because they do have some significant disadvantages.

For one, they aren’t particularly attractive, either from the inside of the house or from the street. Plus they block all incoming light.

If your noise problem is constant, you won’t have the opportunity to remove the plugs which means you won’t be able to enjoy natural sunlight during the day.

Of course, if you live in an area with significant light pollution at night, the plugs’ light-blocking properties could be a benefit.

Installation Guide

• Step 1: Measure the dimensions of your window.
• Step 2: Use these measurements to construct a frame from wooden boards. This frame should fit snugly inside your window gap.
• Step 3: Cut a piece of soundproofing mat to fit inside the frame, and attach it using adhesive.
• Step 4: Add a handle to the frame so you can easily insert and remove the plug.
• Step 5: Insert the plug into the window.
