What Exactly Is a Decibel?
The Logarithmic Scale
The decibel scale is logarithmic — an increase of just 10dB represents a sound that is twice as loud to the human ear. So 40dB isn't "a bit" louder than 30dB; it's perceived as twice the volume. That 10dB gap is the difference between a peaceful night's sleep and reaching for extra-strong coffee.
Perceived Change
- 3 dB: Just noticeable difference
- 6 dB: Clearly noticeable change
- 10 dB: Perceived halving / doubling
- 20 dB: 75% quieter or louder
- 45 dB: Our inserts — up to 97% reduction

Why Your Current Windows Are Failing You
The Single Glazing Problem
Single glass is basically a drum skin. Sound waves hit it, the glass vibrates, and the noise passes straight into your room with almost zero resistance. It might keep the rain out, but it does nothing for the 80dB traffic noise outside.
The Double Glazing Myth
Standard double glazing is designed for thermal insulation, not noise. Because the two panes are the same thickness and close together (16–20mm), they vibrate in sympathy — the "drum effect" — actually amplifying low-frequency traffic rumble.
The Science of Silence: Our 10.8mm Acoustic Glass
10.8mm Laminate
Two glass layers bonded with an acoustic PVB interlayer that absorbs vibration and converts it to heat.
100–150mm Air Gap
A massive canyon for sound waves. By the time vibration crosses this distance, it has lost most of its energy.
Airtight Seal
High-performance compression seals create an airtight environment. If air can't get through, sound can't either.
Why Soundproofing Matters for Your Health
The WHO recommends continuous bedroom noise below 30dB. Constant exposure to London's 70dB+ traffic can lead to:
Increased Stress
Noise triggers fight-or-flight, raising cortisol levels and chronic anxiety.
Sleep Deprivation
Even sub-waking noise prevents deep REM sleep your brain needs to recover.
Heart Health Risk
Long-term high-noise exposure linked to hypertension and cardiovascular disease.
Quick Tips for Checking Your Own Noise Levels
Download an App
Free dB meter apps for iPhone and Android show the difference between windows open and closed.
The "Night Test"
Check levels at 11 PM vs 3 AM. If background stays above 45dB at 3 AM, your windows are failing.
Identify the Source
High-frequency tyre hiss is easier to block. Low-frequency bus rumble needs our heavy 10.8mm glass.
