Our secondary glazing can reduce unwanted external noise by up to 80% PLUS you'll save on your heating bills

Secondary Acoustic Glazing

Our soundproof windows are becoming ever more popular as people look for that little bit of peace and quiet in their lives. Whether you live in a city centre or a quiet suburb, outside noise pollution is unfortunately an issue that no neighbourhood is completely immune to. One of the most significant ways noise enters homes, apartments and offices is through the multitude of windows present. We obviously need them for natural daylight but compared to the walls that typically surround them, they are definitely the weak point.

Soundproof Glazing Installs

Chris M (Soundproofing Job Glossop)
Fantastic service from start to finish with City Insulation. Bibi was efficient, informative and friendly with all the initial phone calls and questions as well as throughout and made the process very easy to understand. Adam was down to earth and professional from the first visit and clearly explained all the options available. From the work being booked in every step was as they had said and they actually finished sooner than planned. It’s a dusty job but was cleaned up really well on the last day with little for me left to do. The acoustics in the house already feel so much better and I haven’t heard the neighbours through any of the walls completed as yet so it’s so far so good. Looking forward to being in the room properly when it’s all decorated and having a peaceful home. Thank you and I would highly recommend City Insulation.

Libby Taylor (Sound Booth Manchester)
These guys are fantastic. I needed a room made silent for the purpose of recording as I am a voiceover with a noisy neighbour. From the start they were polite, clear in their communication and clean, tidy and punctual. Can’t recommend enough. I now have my silent room so I can work with confidence. Thank you

City insulation soundproofed our bedroom which was a party wall in a semi. They worked professionally and cleanly throughout the day, keeping us updated on their progress at all times. We could not be happier with the results - the sound from next door is reduced even more than we expected. Would highly recommend!

Godel Technologies Ltd
After an office move we found speaking to our international clients very difficult due to the echo in 7 of our online conference rooms. City Insulation solved the issue with an effective treatment that enhances the aesthetic of each room and did so with a convenient weekend install so there was no interruption to business. We now have the perfect acoustics in our conference and board rooms and productivity is being maximised.

City Insulation soundproofed our restaurant ceiling against speaker noise reaching the residency above. The results were impressive. Before the noise in the flat was intrusive through the floor but after the soundproofing was completed you could hear virtually nothing. Accessing the ceiling was tricky but the process from start to finish was made easy by Adam and his team. Once soundproofed, they also acoustically treated the space and it now sounds great.

Janet Stringfellow (Rotherham Install)
This company is without a doubt fantastic. I would definitely recommend this business. They are polite, helpful, (they answered all our questions promptly and were very informative), diligent and clean. This soundproofing has given me back my life and it is amazing quality. Do not go with any other business, use city insulations for your soundproofing.
