Night shift workers need quality daytime sleep. Discover how acoustic glazing can block traffic, construction and neighbourhood noise for better rest.
If you work nights—whether in the NHS, security, hospitality, transport, or any of the essential services that keep London running around the clock—you know the challenge of daytime sleep. While the world goes about its business, you're trying to rest in a bedroom that was designed for night-time quiet.
Traffic, construction, deliveries, neighbours, gardeners, children playing—the daytime soundscape is relentless. And poor sleep doesn't just affect how you feel; it has serious implications for your health and your ability to work safely.
Daytime sleep is inherently more difficult than night-time sleep:
Research shows night shift workers average 1-4 hours less sleep than day workers. This chronic sleep debt accumulates, affecting health, mood, and cognitive function.
The health impacts of inadequate sleep are well-documented:
For workers in safety-critical roles—healthcare, transport, security—impaired alertness isn't just a personal problem; it's a professional and public safety issue.
Earplugs reduce noise by 20-30dB but have drawbacks:
White noise masks sound rather than eliminating it. It helps some sleepers but:
Essential for blocking light, but standard blinds provide minimal sound insulation. Even "acoustic" blinds typically reduce noise by only 5-10dB—not enough to significantly impact sleep quality.
For night shift workers, bedroom windows are often the critical intervention point. Properly specified secondary glazing can reduce daytime noise by 40-54d

| Noise Source | Typical External Level | After Secondary Glazing |
|---|---|---|
| Busy road traffic | 70-75dB | 22-30dB |
| Construction work | 80-85dB | 30-38dB |
| Aircraft overhead | 75-82dB | 25-35dB |
| Neighbourhood activity | 55-65dB | 15-25dB |
The WHO recommends bedroom noise below 30dB for quality sleep. With acoustic secondary glazing, this becomes achievable even in noisy urban locations.
The air gap created by secondary glazing provides an excellent space for effective blackout solutions:
Blackout blinds fitted between the original window and secondary glazing are completely enclosed—no light gaps at edges, no dust accumulation, clean appearance.
If your original windows have blackout blinds, the secondary glazing adds acoustic performance while the existing blinds handle light blocking.
We can specify secondary glazing frames in dark colours with minimal reflective surfaces, further reducing light intrusion.
Fresh air is important for sleep quality, but opening windows defeats the acoustic benefit. Solutions include:
For a typical bedroom (2 windows):
Compare this to the cumulative cost of:
For someone spending years on night shifts, acoustic glazing is an investment in long-term health and wellbeing.
Some NHS trusts and employers recognise the importance of supporting night workers' sleep:
