4 Great Ways to Soundproof Your Windows

soundproof your windows

Noise can be stressful, tiring and distracting – no one wants a noisy home. If you’ve got a noise problem in your property, your windows could be the culprit. To make your home more peaceful and improve your quality of life, you might need to soundproof your windows.

If you want to start a soundproofing project, you’ve got a few options to choose from. To get the ideal solution for you, we’ve come up with 4 great ways to soundproof your windows.

1. Fill up gaps around your frames

An easy way to reduce the amount of sound that travels through your windows is to look for any gaps around your frames and fill them up. Frame sealant comes in several different colours so you should be able to find a type that blends in well with your frames. You can also get expanding foam, which is ideal for filling in particularly large gaps. While sealing methods won’t work wonders, they’ll certainly help to soundproof your windows.

2. Invest in noise-absorbing blinds or curtains

Putting up some noise-absorbing blinds or curtains isn’t the most technical solution but it can be effective. They’re designed to soak up noise so when they’re drawn you should notice a reduction in noise. However, they’re only really effective during the night as you’ll want them open during the day. Soundproof blinds and curtains are probably best as a temporary solution or if you’re only bothered by noise during the day.

3. Consider getting secondary glazing

Secondary glazing is a great, long-term way to soundproof your windows. This involves adding an additional layer of glazing to your existing windows. Secondary glazing tends to work better the thicker the new glazing is, provided it’s separated from the original layer by a spacer.

Secondary glazing is a great soundproofing option if your property is listed. If you’re not allowed to replace your windows, adding secondary glazing is a very effective alternative.

4. Get new soundproof windows

Another way to reduce the amount of sound that enters your home is to get soundproof windows. These are made up of frames and glazing that are specifically designed to absorb and reflect sound.

Wood is a particularly good frame material for soundproof windows, especially if they are made up of a combination of different wood types that are cut against the grain. Soundproof windows also need to have at least two layers of glazing that are different thickness to help prevent sound travelling through.

If you’re after a long-term, effective soundproofing solution, fitting new soundproof windows is probably one of the best things you can do.
