Noise Pollution & The Quiet You Didn’t Know You Were Missing

We get used to noise. The low hum of traffic, the neighbour’s lawnmower, the occasional plane overhead. It all fades into the background, or so we tell ourselves. But constant noise doesn’t disappear. It works its way into us, raising our stress levels, disturbing sleep, affecting concentration. The World Health Organisation ranks traffic noise just behind air pollution as one of the most damaging environmental stressors.

For years, most of us haven’t questioned it. Windows were windows, and sound was simply part of city life. But that changes the moment you experience vacuum glazing.
At PassivGlas™, we’ve seen people pause when they first stand inside a room fitted with our glass. They notice the quiet first, the way the air feels softer, the outside world suddenly distant. It’s not silence exactly, but a gentler soundscape and one that lets you breathe, think, rest.

Vacuum glazing works differently. Between two sheets of glass lies a microscopic vacuum that blocks sound far more effectively than traditional double glazing. A standard double-glazed unit might reduce sound by 25–30 decibels; our vacuum glazing can cut up to 41 decibels, depending on installation. That difference means the sound of a busy street can fall from the level of a loud conversation to something closer to the hush of a quiet library.
