4 ways to make windows more soundproof

Who hasn’t experienced it – that irritating noise from outside disturbing the comfort of your own living space? Fortunately, there are ways to reduce noise pollution. On this page, we tell you how to make a window more soundproof using a simple plastic sheet.

Why soundproof your window?

Living in an area where there is lots of noise, often combined with poorly insulated windows, can prove to be quite annoying. But why should you think about soundproofing your window? Soundproofing your windows with better insulation ensures, among other things:

  • Higher living comfort

  • Better sleep

  • Less energy consumption

Ways to soundproof your windows

There are several methods to soundproof your window, depending on your budget and needs. We cover the following options:

    • Secondary glazing
    • Double glazing
    • Soundproof curtains
    • Weatherstripping

1Secondary glazing for soundproofing

Another effective method for soundproofing your windows is to use secondary glazing. Secondary glazing, as the name may suggest, is an additional window that is placed on the inside or outside of the existing window. This creates an extra barrier between your home and the outside world, making it harder for sound to penetrate.

Besides soundproofing, secondary glazing also offers thermal insulation benefits, which can lead to lower energy bills. They are also easy to install and can be a more budget-friendly option than some other soundproofing solutions.

2Double glazing for sound insulation

Double glazing is one of the most popular and effective ways to soundproof your windows. It consists of two panes of glass with an air space between them, which acts as a buffer to dampen sound waves before they enter your home. Besides reducing noise pollution, double glazing also offers the benefit of better thermal insulation, resulting in a warmer house in winter and a cooler house in summer.

Although the initial cost of double glazing may be higher, the long-term benefits, including savings on energy bills and increased home comfort, are often worth it.

3Soundproof curtains: A simple solution

Soundproof curtains are not only an aesthetically pleasing choice, but also a functional one. These curtains are thicker than normal curtains and are often made of dense, heavy material that effectively absorbs and reflects sound waves. They are particularly useful for people living in busy urban areas or near noisy places such as schools, roads or construction sites.

The biggest advantage is their easy installation: you hang them like any other curtain. While soundproof curtains cannot completely block all sounds, they do significantly reduce the amount of noise pollution. They also offer additional benefits such as improved privacy and light regulation.


4Weatherstripping: The finishing touch for sound insulation

Cracks and crevices around windows can be a surprisingly major source of noise pollution. This is where sound can easily seep through, even if you already have other soundproofing measures in place. Weatherstrips are simple, affordable and effective solutions to seal these small gaps. They are made of materials such as rubber, foam or silicone and can be easily applied around a window frame.

In addition to combating noise pollution, weatherstripping also helps to prevent draughts and temperature fluctuations, which contributes to a more comfortable indoor environment and can lead to savings on energy costs. Installing weatherstripping is a DIY task that, with a bit of precision and patience, can produce quick results.


Soundproofing your window can significantly improve your living comfort. It doesn’t have to be difficult or expensive. With the right knowledge and material, you can create a quiet and peaceful living environment.
