Tired of the noise outside? Our windows are designed to block it out. Whether you’re living on a busy street, working with conservation restrictions, or designing for performance, Gowercroft’s acoustic glazing solutions reduce noise to create quieter, more peaceful interiors.
Why Choose Noise Reduction Windows?
Modern life is loud, but your home doesn’t have to be.
Our specially engineered windows reduce unwanted sound by up to 39 decibels, making them ideal for:
- Homes near traffic, schools, or construction
- Listed buildings where window design is restricted
- Projects that demand performance without compromise
From everyday comfort to long-term wellbeing, sound insulation makes a noticeable difference.
How Does Acoustic Glazing Work?
Sound travels in waves. Each time a wave hits a material with a different density or thickness, it loses energy, therefore reducing the sound.
| Glazing Type | dB Reduction | Sound Energy Reduction | What This Means in Practice |
|---|---|---|---|
| Standard Double Glazing | 31 dB | ~1,258 times quieter (10^(31/10)) | Loud street noise becomes more like quiet indoor background noise |
| Silence Pack Glazing | 37 dB | ~5,012 times quieter (10^(37/10)) | Traffic becomes a low murmur, similar to a closed office environment |
| LandVac Vacuum Glazing | 39 dB | ~7,943 times quieter (10^(39/10)) | Heavy urban noise fades to the level of distant, barely audible sounds |

Note on calculation:
Decibel reduction follows a logarithmic scale. Every 10 dB drop reduces sound energy by a factor of 10. So, a 30 dB reduction equates to roughly 1,000 times less sound energy, while a 40 dB drop cuts it by about 10,000 times.
Which Glazing is Best for Reducing Noise?
Standard double glazing reduces noise by around 31 decibels. We offer two advanced options that provide even better performance:
Silence Pack Glazing
Cuts sound energy by around 5,000 times.
- Noise reduction: Up to 37 decibels
- A great choice for blocking everyday noise such as traffic or conversations.
- Outer pane: 6.8mm laminated glass with a sound-dampening interlayer.
- Cavity: 12mm filled with argon gas.
- Inner pane: 8.8mm laminated STADIP Silence glass.
- Suitable for new builds and 20th-21st century upgrades.
- Estimated 8 week lead time.

LandVac Vacuum Glazing
Reduces sound energy by about 8,000 times.
- Noise reduction: Up to 39 decibels.
- Two panes of 4mm glass with a 0.3mm vacuum cavity
- With no air or gas between the panes, sound has no medium to travel through
- Well suited to slim frames and conservation areas.
- Estimated 14 week lead time.

What Frame Material Keeps Sound Out?
The type of frame you choose plays a big role in how well your windows reduce noise.
Timber frames, especially hardwoods, naturally absorb sound. Their dense structure helps dampen vibrations, making them one of the best choices for acoustic insulation. Softwood also performs well and suits traditional designs.
uPVC and aluminium can be effective, but results vary. Aluminium frames without thermal breaks tend to let more sound through. However, modern profiles with multi-chamber designs and insulation inserts can make a big difference.
We specialise in timber frames for their natural sound-blocking performance and suitability for both heritage and contemporary settings.
How do Seals and Window Design Help Control Noise?
You can have the best glass in the world, but if air gets through the frame, so will sound.
That’s why airtight seals and intelligent window design matter so much. Our casement windows feature a double gasket system, which helps create a tighter seal and improves acoustic insulation.
For sash windows, which are traditionally harder to seal, we’ve developed a patented sliding sash seal system. This achieves a Class 4 air permeability rating—the highest in the industry. In real terms, that means far less noise makes it through, even when the window design needs to stay traditional.
It’s these small details that make a big difference when you want a quieter home.
