Acoustic Secondary Glazing

Offices, retail spaces, restaurants and hospitality venues often suffer from high levels of outside noise from nearby traffic, construction, or just busy local environments

Secondary glazing acts as an additional barrier, reducing noise by up to 80% and creating a quieter and more productive indoor environment. Improved acoustic insulation allows employees to concentrate better, enhances customer experiences, and creates a more pleasant atmosphere in which to work.

Here are just a few ways we can City insulation can help

Mind the air gap

Secondary acoustic glazing significantly reduces noise transmission by creating an air gap between the existing window and the secondary glazing unit. This air gap acts as a buffer, absorbing and dampening sound vibrations. The combination of the original window and the secondary glazing unit provides a double layer of glass, which further enhances sound insulation.

Absorbing sound waves

Secondary glazing units are designed with materials that have excellent sound-absorbing properties. Acoustic laminated glass and acoustic seals help to absorb and block out sound waves, preventing them from entering the interior space. This reduces the impact of external noise sources, such as traffic or construction, and creates a quieter environment.

Engineered to minimise noise

Secondary glazing units are specifically engineered to minimise sound transmission. They break up sound waves, reducing their ability to travel through the window. We use high-quality materials and precise installation techniques to further enhance the soundproofing performance of each secondary glazed unit.

Different materials for different results

By using different glass thicknesses, laminates, and acoustic seals we can customise secondary glazing to suit specific noise control requirements. Additionally, the air gap between the existing window and the secondary glazing unit can be adjusted to create an optimal acoustic barrier. This ensures that a secondary glazing solution is tailored to address the specific noise challenges of your commercial premises.

City Insulation can incorporate secondary glazing into your commercial premises, to create a peaceful and productive environment. Improved acoustics contribute to better concentration, increased privacy, and enhanced customer experience.

David M.

I requested that City Insulation take on several projects at my apartment in Manchester, including reinsulating most of the walls and adding secondary glazing for acoustic/thermal insulative properties to all the windows, as my apartment is centrally located in an area with significant noise disruptions during peak times, city events, and so on. The company was thoroughly professional throughout, including working to fit things matching the original fixtures and fittings of the property with the appropriate RAL colours and trims, and the insulation work additionally involved preparing a new... recess/infill section and adding an extra cupboard space, as well as managing electrical changes and other complexities. The whole process was managed carefully with great results, so I would highly recommend them.read more

We'd had problems with noise from our neighbours – loud TV, loud phone conversations – which had become so intrusive we were considering moving. But we love our house, so instead, we decided to get "proper" sound proofing done by City Insulation, and we're really glad we did. Intrusive noise has been pretty much entirely eliminated and we feel like our home is our own once more. Jack and Nick did the work and were a pleasure to have in the house. They talked us through what they were doing, kept us up to date with progress and cleaned up thoroughly once they were done.

Adam and the team at City Insulation (Nick and Jack) we all amazing. Everything was great from the first consultation call to the installation of the soundproofing wall. I was having issues with noisy neighbours in a new build apartment. Now we can't hear a thing since the installation.

Adam and team recently soundproofed our living room. The work was done efficiently and professionally, and communication was outstanding. If we need any further work in other rooms we'd be happy to go back to them.

Andy Newman

City Insulation installed secondary glazing throughout our two bedroom flat in a converted mill in Ancoats, Manchester. The difference it has made is astonishing with regard to reducing sound levels (cobbled streets, geese on the canal and late night revellers) and improving warmth.The work was done cleanly and quickly and at a price that beat competitors.

Rachel was very helpful and prompt in providing me with a quote and clarifying everything necessary.Adam, the fitter, payed meticulous attention to detail and did a perfect job of fitting the window.I would honestly highly recommend and will use again in the future.

Adam visited our property to advise on noise from a pool plant room that was coming into the house. He advised on the best approach to eliminate the vibration that was being heard. On his advice this has now been resolved. Adam was great to deal with and we would highly recommend his company

Katja Kimberger

The customer service was fantastic with our quotes updated several times to match our requirements. The team that came out were very efficient and stayed late to finish the job in one day without being asked to. The sound proofing is of really high quality and we haven't heard any noises at all from our neighbours since it was installed

Peter Davis

I can't praise City Insulation enough they are very professional, informative, courteous and they certainly know their stuff. They completed our lounge and dining room soundproofing in two days, which was completed with great care and respect to our home and furnishings (thanks to a great installation team). Do yourself a favour and choose City Insulation, it's no surprise that they get regular 5 star ratings.

Adam & Rachel were professional, knowledgeable and genuine people to deal with. I knew nothing about sound proofing but they talked me through all my options to help me understand the best options for my particular wall. They were also really helpful on suggesting work that fitted within my budget, there were other more expensive options but they recommended the best package for me that would have the most impact not just the most expensive. The sound proofing they installed on my party wall to reduce noise from neighbours (screaming children, overly loud tv, shouting etc..) has been game changing. Since being completed me and my partner can now sit and have a conversation without having to put music or tv on in background to drown out the neighbour noise. The work was very professional, the finishes excellent and all the lads took real care to protect existing furniture, carpets etc... The work was completed in a very professional manner and attention to detail was fantastic. Some firms do their bit and leave but they even arranged for other tradesmen to help complete the redecoration work after they had left i.e. plasterer, plumber (to re-mount a radiator) whose work was also of an equally excellent standard. I would highly recommend city insulation to anyone wanting to work with a truly professional business whose end product does exactly what it says on the tin! Thank you Adam & Rachel you were a pleasure to deal with.

I recently used City Insulation to help with soundproofing my semi-detached house. I could hear my neighbours TV, door slamming and arguments, to the extent that I felt like I lived with them! City Insulation installed their ‘Independent Wall plus both upgrades’ system on every adjoining wall to my neighbours and the results have been great! The noise has been reduced by around 80% in the three rooms and I no longer feel the intrusion from next door. I knew nothing about soundproofing before the job was done, and City are not local to where I live so it was a bit of a’ leap of faith’. However, Rachel has been fantastic in responding to all my queries, Adam was really knowledgable about getting the right solution for me and the installation team (Nick, Jack and Brad) were so efficient in getting the work done and to a really high standard. Thank you team for all your help - it’s really appreciated!

Annie McGoff

From start to finish City Insulation were extremely efficient, friendly and professional. From visiting on site to discuss the problems we had with soundproofing, to providing a solution and competitive quote, and to finally completing the work. The workmen were courteous, did a very good job and left no mess! We would highly recommend.

Anita Banerji

We had a wall soundproofed in our bedroom and it’s made a big difference. Rachel was really prompt and friendly with responses from our initial enquiry to completion and knowledgeably answered all my queries. The installation team were prompt and friendly and I was happy to just leave them to it. They did an excellent job and we used the recommended plasterer too. Would highly recommend and you don’t have to wait long to get the work done.

Jimmy Shaw

City Insulation provided exceptional service for my secondary acoustic glazing needs for my bedroom. Rachel was very understanding and patient, providing all the necessary details before the job completion and answering all my questions. Adam turned up when he said he would and fitted the secondary acoustic glazing to a very high standard, leaving no mess and a very professional job. Adam and Rachel are genuine, honest and very likeable people. City Insulation is an extremely well run company and possibly the best for soundproofing in the UK. I sincerely wish City Insulation every success for the future.

Many thanks to the team for installing the soundproofed wall all along the partition wall from one side of the house to other completely sealing off the noise disturbances I had to deal with.The team of three took two days and worked their hats off with exemplary workmanship and showed ingenuity fixing a challenging situation that they’d encountered.They also set up the house with protection prior to starting and cleaned up inside and outside the door where they worked in poor weather conditions.All in all, I will definitely call them again for any issues and I wholeheartedly recommend them. Adam and Rachel from the office were very helpful in answering all the queries I initially had.

Richard Reeves

Great work from the team. The soundproofing on our 1930s semi has far exceeded our expectations. Our lounge is now so peaceful! They worked really hard, from start to finish, putting the room back together again so you’d never know they’ve been (but for the need to decorate 😉). Great advice from the outset, so glad we’ve done it.
