• Up to an 80% reduction in noise
  • Stop noise coming in or out of your commercial windows
  • Improve security

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.

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 more

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!read more
