How To Soundproof Your Windows

Windows are often forgotten when it comes to soundproofing a room, this is because it is easy to forget that people outside your house may be disturbed by the noise you plan on unleashing.

Soundproofing your windows will ensure that you can maintain a vaguely amicable relationship with your neighbours even after a noisy party!

When planning how you will soundproof your windows it is important to be aware of what type of sound you are seeking to block out.

High pitched sounds are far easier to proof your window against than low pitched sounds such as the rumbling of traffic.

If you need to soundproof your window against a low pitch sound then you will probably need to spend more to achieve the desired results.

As a general rule soundproofing your window can be done by:

  • Increasing the size of the cavity between your glass (installing acoustic grade glass will help with this).
  • Increasing the density of your window panes.
  • Using an insulated frame (or just making sure that your existing frame is thoroughly sealed all the way around)
  • Adding Acrylic Panels.
  • Using sound deadening curtains.
  • Or completely blocking your window!

There are many different methods you can employ to soundproof your windows some more effective than others and of course the cost of each method will vary significantly.

For the very best results combine as many of these methods as possible.

For example you could install acoustic glass with a well sealed insulated frame. Then you could hang a sound deadening curtain over it and you could also get a sound blocking panel to fit your window that you could place in the window frame every time it’s about to get noisy!

1) Installing Soundproof Windows

If you have budget to spare then a good option is to invest in triple pane windows, these of course aren’t cheap. However they are very effective in significantly reducing the transmission of sound.

Make sure you buy a triple glazed window with a laminated middle pane. A plastic middle pane will absorb vibrations and deflect sound.

When your new windows are installed that they should be installed precisely and carefully sealed with no cracks or gaps around them as this will completely compromise them.

Noise Reduction/Acoustic Grade Glass

Another option if you are considering getting new windows is investing in Noise Reduction Glass (sometimes known as acoustic glass)

This has four thick panes of glass, two either side of the cavity. These are bonded together with a polyvinyl butyral (PVB) interlayer which become clear when heat and pressure are applied to it.

PVB not only helps seal the glass together but it also acts as a noise dampener and absorbs sound energy as it travels through the window.

Acoustic glass is one of the most effective solutions for soundproofing a window.

2) Soundproof Your Windows With Acrylic Panels

Another option is to add acrylic panels to your windows.

These are a low cost option which are commonly used on homes which have old fashioned single pane windows in.

Adding acrylic panels is a cheap and effective way of reducing the amount of sound that your single pane windows let through. It will also help reduce sound on a standard double glazed window and will help improve the heat insulation on your window (this is usually the main reason why people install them).

These come with magnetic frames. To install them you simply need to fit the thin metallic frame around your window (which comes with them) and then slot the acrylic frame into place so that the magnetic frame attaches to the metal frame.

They can be easily removed to clean the window if necessary.

Acrylic panels are a cheap and affordable option for adding a bit of extra soundproofing and insulation to your window however they are not going to make a huge difference to how much sound your window lets through so are own useful for dealing with low level noise.

3) Use Heavy Curtains to Deaden Sound

Thick heavy curtains will deaden sounds going through them.

Soundproof curtains are very dense and made of heavy fibres so if you are going to install them make sure you have a very sturdy curtain rail to hang them from which can definitely take the weight.

Soundproof curtains certainly won’t prevent all noise getting through but they will at least muffle noises so are good for low level noise problems.

They are a valuable sound deadening addition to any of the methods we have previously mentioned.

4) Blocking Your Windows

The most effective way of soundproofing a window is to block it completely, this can easily be done with dense rubber insulation panels, the same sort which you can use to soundproof your walls or you could use a fibreglass soundproof blanket.

To do this simply buy a barrier panel, and cut it to fit the exact size of your window frame, this can be removed and replaced as and when you need your window to be soundproof.

Obviously completely blocking your window is not always desirable.

If you want to be able to enjoy the experience of having both noise (or lack thereof) and light at the same time in your room then there are plenty of other options available as we have mentioned above.
