Understanding Traffic Noise
Traffic noise is one of the most common and disruptive forms of environmental noise pollution. Consisting of mixed frequencies from engine rumble (low), tire noise (mid), and horns/brakes (high), traffic requires specialized acoustic solutions that address the full frequency spectrum. Whether you're dealing with bedroom noise issues or need workplace productivity improvements, the right acoustic windows can transform your environment.
Noise Levels
- • Quiet street: 50-60 dB
- • Busy road: 70-80 dB
- • Motorway: 80-90 dB
- • Heavy traffic: 90-100 dB
Target Reduction
- • Moderate: 15-20 dB (noticeable)
- • Significant: 25-35 dB (comfortable)
- • Maximum: 40-50 dB (library quiet)
Best Solutions for Traffic Noise
Laminated Acoustic Glass (Recommended)
The gold standard for traffic noise. PVB interlayer dampens vibrations across all frequencies.
- STC 40-48 (double pane)
- STC 48-55 (triple pane)
- Reduces traffic by 80-95%
- Properties on busy roads
- Near motorways/highways
- Maximum noise reduction
Triple Pane with Asymmetric Glass
Three panes of different thicknesses prevent resonance amplification of traffic frequencies.
- 6mm + 8mm + 10mm glass
- Optimized air gaps
- Argon gas fill
- STC 50-55+
- Excellent energy efficiency
- Long-term value
Secondary Glazing System
Cost-effective solution adding acoustic layer to existing windows without full replacement. Learn more in our comprehensive secondary glazing guide.
- 100-150mm air gap
- 6-10mm laminated glass
- Acoustic seals
- STC 45-50
- Lower cost (£400-700/m²)
- Keeps existing windows
Choosing Based on Traffic Volume
🟢 Moderate Traffic (60-70 dB)
Residential streets with regular but not constant traffic
Solution: Double glazed with 6.4mm laminated glass + secondary glazing option
Expected Reduction: 20-30 dB (comfortable indoor environment)
Investment: £600-900 per window
🟡 Heavy Traffic (70-85 dB)
Main roads with constant traffic throughout the day
Solution: Triple pane with laminated glass or double pane + secondary glazing
Expected Reduction: 35-45 dB (quiet indoor environment)
Investment: £900-1,400 per window
🔴 Extreme Traffic (85+ dB)
Motorways, highways, or major urban thoroughfares
Solution: Triple laminated + secondary glazing (quad-pane system)
Expected Reduction: 45-55 dB (library-quiet indoor space)
Investment: £1,400-2,000 per window
