ᐅ Improving Sound Insulation of Windows

Hello everyone,

Is there a way to improve the sound insulation of windows afterwards? I once read something about films, but I’m not sure if they really help. I was told that windows with better sound insulation have a special gas in the panes. Would it be possible to "upgrade" this later?

Thanks in advance

What type of windows are we talking about? Are they new or old? For old ones, proper adjustment and replacing the seals could already help.

Hello Gerd,
Perhaps an acoustic curtain could help you improve sound insulation. I once stayed in a hotel on a very busy street, and they had an electric curtain installed. It really did its job well. The curtain was very heavy, and to me, it felt like it was made of several different layers of fabric with a kind of small lead ball chain at the bottom. The balls kept the curtain stretched. You could definitely notice how much sound it absorbed.

Since the original poster did not mention the age of the windows, I would first check the adjustment and seals.

Then you could consider replacing the glass with a special type that offers sound insulation. These usually have a special film embedded in the outer pane, similar to laminated safety glass, which reduces noise. While it’s not a miracle solution, a reduction of 40-45 dB is possible.

This will likely change the total thickness of the double glazing (and the weight), so it must be compatible with the existing window frame.

Maybe provide some information about the current windows: material, age, frame manufacturer (if known), and the type of glass currently installed...
