In an increasingly noisy world, creating a calm, restorative home environment has never been more important. Whether you live near a busy road, flight path, railway, or simply want to eliminate everyday disturbances, noise control is now a key part of modern architectural design.
Internorm’s premium triple-glazed windows and large lift & slide doors deliver exceptional acoustic performance – helping homeowners and architects create spaces that feel protected, comfortable and quiet.
Why Noise Reduction Matters for Wellbeing
Noise is more than just an inconvenience – it has a measurable impact on physical and mental health. Research from the World Health Organization (WHO) shows that long-term exposure to noise can contribute to stress, increased heart rate, irritability, fatigue and reduced cognitive performance.
Most importantly, environmental noise is one of the leading disruptors of healthy sleep. Even low-level sounds can fragment sleep stages, prevent deep rest, and reduce morning alertness. For homeowners, this can mean lower productivity, lower mood, and reduced overall wellbeing.
A quieter home supports:
- Higher-quality, restorative sleep
- Reduced stress and mental fatigue
- Improved concentration and home-working environments
- A greater sense of comfort and sanctuary
How Triple Glazing Reduces Noise
Internorm’s triple-glazed systems are engineered with multiple layers of acoustic protection and can achieve up to 48dB in sound reduction:
1. Three Panes of Glass
Three layers of glass create multiple barriers for airborne sound waves to pass through, significantly reducing decibel levels compared to double glazing.
2. Varying Glass Thicknesses
Using asymmetrical glazing reduces resonant frequency, preventing soundwaves from travelling directly through the glass.
3. Deep Frame Construction
Internorm’s energy-efficient frames contain insulating materials that absorb vibrations before they enter the room.
4. Airtight Sealing
Acoustic performance depends on airtightness -and Internorm’s I-tec Glazing and triple gasket systems prevent noise infiltration around the window frame.
The result: a calmer, quieter indoor environment – day and night.
Where High-Performance Triple Glazing Makes the Biggest Difference
Certain home environments benefit significantly from acoustic protection. These include:
- Homes near roads or motorways
- Properties close to airports or flight paths
- Urban or city-centre apartments
- Railway or tramline locations
- Newly created garden offices or studios
- Homes with large glass areas or open-plan living
Internorm’s large lift & slide doors, often used in contemporary architecture, benefit especially from triple glazing due to their oversized glass panels.
The Role of Internorm Lift & Slide Doors
Large panoramic doors are beautiful – but can also be vulnerable to sound transmission if poorly designed.
Internorm lift & slide doors are built to last. They are highly energy efficient and also offer:
- Triple glazing as standard
- High-performance acoustic insulation
- Exceptional airtightness
- Secure, multi-point locking and high structural rigidity
Quiet Mark Certification – Independent Proof of Acoustic Excellence
