Soundproofing windows can be a challenging task. Because of the way windows are built, sealing their openings effectively to help soundproof your space requires some effort. However, with the right materials and approach, you can reduce noise coming through your windows by up to 50%. In this article, we’ll give you all the information you need on how to seal leaky windows and enjoy a quieter space in no time.

How to Soundproof Windows.

Soundproofing windows is a challenge, but it is possible. It’s best to do this in stages, starting with your most problematic areas and working outwards.

If you want to soundproof your entire home or apartment window-by-window, there are two main ways to go about it: acoustic foam or acoustic glass. The former can be purchased at hardware stores and installed by yourself; the latter can only be installed by a contractor. The choice between these two options depends on how much money you have available for soundproofing materials and labor costs (if any).

If you’re not sure which method would work best for your specific situation—if you think that your windows could use some TLC—then call around to find a contractor who specializes in window repair (or just ask around!). They’ll be able to tell you what kind of repairs need doing before they start installing acoustic glass or foam into each individual window frame.

Why Soundproofing Windows Is So Difficult.

In the previous section, we discussed some of the factors that make windows so difficult to soundproof. This can be a confusing subject for many people because even though people know that windows are a common source of noise, they often fail to understand how sound passes through them in order to reach their ears.

Soundproofing with Acoustic Foam Window Plugs.

Acoustic foam plugs are a cheap and easy way to soundproof windows. They’re also very effective, and can be used in a variety of situations.

If you’re looking for an affordable way to soundproof your home or office, acoustic foam plugs are the cheapest option. These are small pieces of foam that come in rolls or sheets, and they have adhesive backing so you can stick them on your window sills or sill plates (the part where the sill attaches to the wall).

Acoustic foam comes in a variety of colors; this is important because different colors absorb different frequencies of sound energy. For example, black absorbs high frequencies while white absorbs low ones—this means that black will always be better at blocking high frequency sounds like voices than white is at blocking low frequency ones like music or cars driving by outside on Main Street. But if you want something more subtle (for instance), there are other options available too!

DIY Soundproofing with Acoustic Foam Panels.

The first step to soundproofing windows is to gather the necessary materials. Check out our blog on how to measure window size if you need help determining how much foam you’ll need.

  • Acoustic foam panels (we recommend using two 4’x8′ sheets)
  • Electrical tape or duct tape, for attaching the panels to each other and their frame
  • A sharp utility knife, for cutting the acoustic foam into pieces that can fit in your windows (we recommend a blade with a retractable base)

Once you have all of these items, it’s time to start installing! First, cut the acoustic foam sheets into rectangles approximately 2″ thick by one inch wider than your window frame. Lay each piece over its corresponding window opening and press down firmly so it sticks well against both sides of the frame; use an old credit card or similar tool if necessary for this process—you don’t want any gaps between them otherwise they won’t function effectively as soundproofing material! Next comes cutting holes at regular intervals along one side of each rectangle — this will allow air circulation while also keeping bugs out during warmer weather months when there isn’t any precipitation outside yet but still may be humid inside due over-heating temperatures caused by sun coming through glass panes without insulation present between them (which is exactly why we suggest using double panes). Finally apply electrical tape around edges where two pieces overlap together so they don’t unravel while also sealing off any gaps left behind after cutting around doors/windows etcetera–this will ensure that air doesn’t leak through seams during hot days where warm air rises up from below street level up towards higher floors within buildings.”

Replacing Windows with Acoustic Glass.

Replacing your windows with acoustic glass is a great option if you’re looking for a more permanent solution. It’s expensive, it takes more time to install than other options, but it comes with a number of benefits.

  • Acoustic glass is more energy efficient than regular windows. It insulates the heat and keeps your home warmer in winter and cooler in summer, which means you can keep your heating bills down while still maintaining comfort levels inside your home.
  • Acoustic glass is also more durable than conventional windows, meaning that they will last longer and save you money on the longterm cost of repairs or replacements over time.
  • Finally, acoustic glass offers better soundproofing than other types of window materials because it blocks outside noise without sacrificing heat or light insulation properties like some other window types do — making them ideal if you’re looking for maximum protection against outside noise while still enjoying all of the convenience features that come along with having an open window!

Working with a Contractor.

  • How to find a contractor:
  • Ask friends and neighbors for recommendations.
  • Check with your local chamber of commerce or trade association.
  • Search online for contractors in the area. Search by location, specialty, company name and type of work they do (building, remodeling or landscaping). When you find one or more companies that appeal to you, contact each one and ask if they offer any work that fits your project description (“I need someone who can soundproof my windows”).

Sealing the gap around windows can be challenging, but it’s not impossible and the results are worth your while!

Sealing the gap around windows is not an easy task, but it’s definitely a worthwhile one. If you want to make your home more comfortable and quiet, sealing the gap around your windows is an option that can be worth your effort. However, some windows cannot be soundproofed and others are best left alone because of their unique construction.

You may also have to consider whether or not you’re interested in performing this project yourself or hiring someone else to do so. Either way, if investing time and money into making your home quieter sounds appealing then read on!


If you’ve been dealing with noisy neighbors or just want to create a quiet space in your home, then soundproofing windows is a great way to do it. There are plenty of ways to reduce the noise coming through your windows. The most important thing is to be proactive and try different methods until something works for you. If none of these solutions seem like they’ll work, then it may be time to call an expert!
