How to Soundproof Your Denver Windows

Gary Harding

Do you ever have a situation where you’re woken up early in the morning by traffic or a neighbor’s all-night party and wished that you could keep outside noises where they belong?

Noise comes into your house through openings, crevices, and through material like glass and can lead to sleepless nights. Windows, in particular bigger, older windows, are a major source of noise disturbing your home, and by soundproofing your windows you can drastically cut back on unwanted noise.

Here are a few things that Denver homeowners can do to soundproof your windows and lessen noise from outdoors.

Add caulk or weatherstripping to the window frame

Adding caulk or weatherstripping is an inexpensive DIY solution to soundproof your windows. Since air carries sound waves easily, blocking any gaps or openings by your windows will help reduce sound. One thing you can do is add foam tape to the sides of your window sashes. For a double-hung window or a sliding door you can use vinyl v-strips on the exterior of the windows. You can also caulk the crevices around windows and over any splits to stop airflow.

One downside of this DIY solution is that it’s not a long-term solution, and it might damper how good your windows look.

Add sturdier window treatments like plantation shutters

installing heavy window treatments such as Denver’s best plantation shutters can help soundproof your windows immensely.

Plantation shutters are an eye-pleasing way to block the sound coming through your windows while also improving your home’s energy efficiency. Polywood plantation shutters have a patented built-in weatherstripping design that locks out unwanted noise and temperature.


Polywood plantation shutters are resilient, which means that they’ll last a lot longer than those DIY solutions. They are more affordable than installing new windows, and after they’re put in are a permanent piece of your house, which can increase your home’s sale value on the market.

Put in a sound-proofing plug

If you experience constant noise like construction noises you could benefit from a sound-proofing plug. This DIY option is a large piece of foam that you slide into the gap around your window. Since the foam blocks light (and might look out of place), people use sound plugs in the evening or in rarely-used rooms.

Replace or add additional windows

If your windows are older and you're suffering from air drafts as well as unwanted noise, it’s probably time to think about replacing your windows. If replacing all your windows is outside of your budget, you can put in exterior storm windows or an additional window pane to problematic windows. The drawback is that getting new windows or adding extra panes can still be a pricey option.
