Let’s first discuss what is exactly secondary glazing and how it works. Secondary glazing works by installing additional layers to an existing window When the unwanted noise travels through the air, it easily passes through the single-glazed timber window.

However, Secondary glazing works by adding a layer to the single-glazed window. This creates a gap between the two panels. When the noise travels through the window, the noise stays between the two panels.

This air gap works as a cushion, absorbing and vanishing soundwaves, therefore, reducing the amount of noise entering your home. Secondary glazing is very effective at completely vanishing noise, reducing it by up to 80%.

They can be customized to fit your window size and are available in different thicknesses to enhance noise reduction, making it great option for homes.
