Adding secondary glazing to your home can play a major part in helping to define acoustics around the house, either as a standalone installation, or in conjunction with a broader set of acoustic measures – the most transparent way to create an acoustic-friendly home environment.

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

Widening the gap brings sonic clarity

Secondary 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 glazed unit provides a double layer of glass, which further enhances sound insulation, and naturally creates acoustic clarity.

Acoustic materials are employed

Secondary glazed units are designed with materials that have excellent sound-absorbing properties. Acoustic laminated glass and acoustic seals help to absorb and dissipate 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 the noise

Secondary glazing units are specifically engineered to minimise sound transmission, and maximise a clean acoustic environment. By breaking up sound waves and disrupting their path, soundproof glazing reduces their ability to travel through the window. We use high-quality materials and precise installation techniques further enhancing the soundproofing performance of secondary glazing for good acoustics.

Address specific acoustic challenges

Different glass thicknesses, laminates, and acoustic seals can be used to customise secondary glazing for specific noise control requirements. Additionally, the air gap between the existing primary window and the secondary glazing unit can be adjusted to create an optimal acoustic barrier. This ensures that the secondary glazing solution is tailored to address any specific noise challenges your home faces.

Just one way to achieve great acoustics

Secondary glazing can be combined with other acoustic solutions to further improve sound insulation. For instance, the use of double glazing in combination with secondary glazing provides even greater sound reductions and strong acoustics. A mixed approach to acoustics addresses different frequencies and types of noise.

City Insulation can incorporate secondary glazing into your home to create a peaceful and productive living space. Improved acoustics contribute to better concentration, increased privacy, and a more harmonious family life for all.

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 K.
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 D.
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.
