• 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.

Great experience start to finish - quickly came round and quoted, providing confidence in what they would do and who would be involved, co-ordinated all the individual workers who worked to a high standard. The work itself was done to a high quality and on-time, and the difference has been amazing - great company, would highly recommend.

We are all absolutely delighted with City Insulation and the work they have just completed at my brother's house in Liverpool. Sadly my brother is living with alzheimers now and he does have some noisy outbursts now and again, which is natural for this horrible illness. He is being cared for 24/7 in a normal semi-detached house in Liverpool however his neighbours are not normal and keep complaining and putting in complaints to the police / council etc. I found Adam/City Insulation on the internet and he was so understanding and came up with exactly the right solution. All the carers in... the house are delighted and its made their job easier as they no longer worry about the next door neighbours who have got to find something else to complain about now! A big thanks to Adam and his team and if you have any noise issues etc you now know who to contact! (Ps very clean, very quick job, great value for money)read more

Best experience I've had with any tradesman to be honest. We needed to improve soundproofing in commercial meeting rooms/studios and he laid out the different options very clearly so we could make the best decision from a range of budgets. His team were extremely professional, delivered the work exactly when they said they would with zero delays. Very friendly and flexible with everything onsite. Would thoroughly recommend.
