Noise Reduction in Urban Developments: Timber Window Acoustic Solutions
January 8, 2026 | News | Written by Nicola Harrison
Urban living comes with many advantages, but constant noise pollution isn’t one of them. For trade installers and developers working on city-based residential commercial projects, specifying the right soundproof timber windows can make all the difference.
In densely populated urban environments, external noise from traffic, construction, airports, and railways can significantly impact quality of life. This is where acoustic timber windows from Bereco offer a perfect solution, combining exceptional sound insulation with the natural beauty and sustainability of timber.
Why noise reduction matters in urban developments
Prolonged exposure to high levels of noise pollution can affect sleep quality, concentration, and overall wellbeing.
Modern buyers and tenants increasingly expect homes to provide a peaceful environment, even on a busy street. Similarly, developing properties near airports, main roads, or railway lines presents particular challenges when it comes to external noise levels. Installing effective soundproofing solutions during construction is far more cost-effective than retrofitting later.
How acoustic timber windows work
Bereco’s acoustic timber windows reduce unwanted noise through a combination of specialist components working together as a complete system. Unlike some suppliers who only certify the glass, Bereco’s acoustic performance is BlueSky certified for the entire window unit—giving you complete assurance that the stated dB rating reflects real-world performance.
Acoustic glass technology
At the heart of acoustic windows sits specialist acoustic glass. This comprises two glass panes laminated together using an acoustic membrane. This membrane absorbs sound energy and prevents vibrations from travelling through the glass, dramatically reducing sound transmission.
The acoustic glass used in Bereco windows achieves security ratings of P2 and P4 as standard, surpassing the P1A required for Secured by Design and Part Q of the Building Regulations. This means you’re delivering both sound reduction and security in one solution.
Dual gasket sealing system
Sound leaks are a common weak point in window installation. Bereco acoustic timber windows feature dual gaskets that create an exceptional seal. These gaskets serve multiple purposes: they prevent air leakage, improve weatherproofing, and crucially, stop sound waves from bypassing the glass.
Proper sealing is essential for achieving the full acoustic performance potential. Even the best acoustic glass will underperform if gaps allow noise to penetrate around the frame.
Engineered timber frames
Timber window frames play a crucial role in soundproofing properties. As a natural material, timber has excellent acoustic properties that synthetic materials simply cannot match. Wood windows naturally dampen vibrations and absorb sound energy more effectively than vinyl windows or aluminum windows.
Bereco’s engineered timber frames are manufactured from FSC® 100% or 100% PEFC Certified timber, providing both exceptional acoustic performance and sustainability credentials that modern developments demand.
Bereco’s ambient range: certified acoustic solutions
For installers and urban developers seeking reliable, high-performance soundproof windows, Bereco’s Ambient range offers measured sound reduction from 33dB up to an impressive 42dB.
Performance you can trust
All Bereco acoustic timber windows are independently tested and BlueSky certified. This third-party certification covers the complete window system—not just the glass panes—giving specifiers and installers confidence in the performance figures.
Here’s what different levels of noise reduction mean in practice:
– 33dB reduction (standard double glazing): Suitable for moderately noisy urban environments, reducing typical street noise to comfortable indoor levels
– Up to 42dB reduction (Ambient range): Ideal for properties close to airports, major roads, or railways where external noise is particularly intense
To put this in context, a 42dB reduction can transform noise from a busy main road (approximately 70-80dB) into the sound level of a quiet library (around 30-40dB).
A-rated sound reduction
Bereco has achieved BlueSky certified A-rated noise reduction levels with the Ambient range. This represents the highest standard in acoustic performance, helping you create homes of calm and tranquillity in even the most challenging urban environments.
Wide range of styles
The Ambient acoustic range is compatible with multiple window styles, including:
Note that acoustic glass is not currently compatible with Bereco’s Heritage range.
Additional benefits for urban installations
Energy efficiency
Acoustic timber windows don’t just reduce noise pollution—they also deliver exceptional thermal performance. Bereco’s double glazed timber windows exceed the new Part L 2023 building regulations and can achieve impressive U-values starting from 1.3 W/m²K—which is 7% better than the guidelines. Triple glazed windows achieve U-values starting from 0.8 W/m²K, which is 43% better than what’s stipulated in the regulations.
This dual benefit of sound insulation and thermal insulation makes acoustic timber windows an intelligent specification choice for urban developments where both noise and energy efficiency matter.
Sustainability credentials
Modern developments increasingly require robust sustainability credentials. Bereco timber windows are manufactured from FSC® 100% or 100% PEFC Certified timber, with full traceability back to sustainably managed forests. With proper installation and maintenance, these windows offer an up to 60+ year lifespan.
Security as standard
Urban properties require robust security. All Bereco doors feature home insurance approved multipoint espagnolette locking and Neighbourhood Watch approved ERA Fortress door cylinders. The acoustic glass achieves P2 and P4 security ratings as standard, exceeding requirements for Secured by Design and Part Q.
Aesthetic appeal
Bereco’s acoustic timber windows can be fully customised with different types of bar designs, ironmongery styles, and single or dual colour paint and stain finishes. This design flexibility means you never need to compromise aesthetics for acoustic performance.
Real-world applications
Acoustic timber windows prove particularly valuable in:
- Apartment developments near major transport hubs
- Mixed-use developments combining residential and commercial spaces
- Conversions of period properties in busy urban areas
- New builds on former industrial sites near railways or main roads
- Luxury developments where peace and quiet commands premium pricing

Frequently asked questions
What level of noise reduction can I expect from acoustic timber windows?
Bereco’s standard double glazing provides 33dB sound reduction, whilst the Ambient range achieves up to 42dB—enough to reduce busy main road noise to library-quiet levels indoors.
How do acoustic timber windows compare to other materials?
Timber window frames have superior natural insulating properties compared to different materials. Wood naturally dampens vibrations and absorbs sound energy more effectively than vinyl or aluminium alternatives.

Can acoustic windows achieve the same energy efficiency as standard windows?
Yes. Acoustic timber windows also improve energy efficiency by providing superior insulation, reducing heat loss and preventing drafts. Bereco’s acoustic windows achieve U-values from 1.3 W/m²K with double glazing and 0.8 W/m²K with triple glazing, exceeding Part L 2023 requirements by 7% and 43% respectively.
Are acoustic timber windows suitable for period properties?
Acoustic glass is compatible with most Bereco ranges but not the Heritage range. Bereco’s technical team can advise on the best acoustic solution for period properties.
