There’s quiet. Then there’s The Soundproof Windows
Specified by an acoustician. Installed by specialist craftsmen.
We design and install bespoke timber acoustic windows, secondary glazing and doors for period and modern homes, including properties in conservation areas and listed buildings. Each system is designed around the building, architectural details and noise problem, combining acoustic specification, traditional timber joinery and careful installation to reduce intrusive external noise while improving thermal comfort. As a family-run, acoustician-led business, our aim is to create a noticeably calmer home without compromising its character.

Acoustic performance is more than glass
Acoustic performance depends on far more than the glass alone. We consider the noise source, frequency profile, existing windows, frame design, glazing specification, seals, available cavity, ventilation and installation before recommending a suitable system.
By combining carefully selected acoustic glazing with bespoke timber frames and airtight installation, we aim to reduce intrusive external noise while preserving the appearance and character of the property.
The appropriate specification and achievable improvement will vary between homes, which is why we assess the complete opening rather than relying on a single headline decibel figure.
All without compromising architectural character.
Understanding the noise
Not all noise is the same, and neither is the appropriate solution. Road traffic, aircraft, trains and late-night activity have different characteristics and may require different glazing, frame and installation strategies. We consider the source, the existing windows and the surrounding construction before recommending the most suitable approach.
Designed around your home
Our bespoke timber windows and secondary glazing are designed to respect the character of period and modern properties. Frame profiles, glazing, seals, opening style, finish and installation details are considered together to reduce intrusive external noise without compromising architectural appearance.
Crafted, installed and supported
Each project combines specialist timber joinery with careful acoustic installation. As a family-run business, we take responsibility for the project from initial assessment through to completion, with clear product warranties and insurance-backed protection available on eligible installations.
