Sound reduction windows, explained

Start with the noise

Road traffic, passing trains and voices have different sound characteristics. Tell us what you hear, which room it affects and when it is most noticeable. That helps us assess the opening before discussing a configuration.

Sound can also travel through other openings or the building structure. A new window is most relevant when the window opening is an important part of the problem.

Understand the window as a whole

• Glass: thickness, laminated layers and combinations of panes affect acoustic behaviour. Acoustic laminated glass uses an interlayer designed to damp vibration.
• Cavity: the space between panes is part of the specification. Pane count alone does not establish performance.
• Frame and seals: the sash, hardware and seals need to close properly.
• Installation: the junction between the frame and wall also needs attention.

Opening style matters too. Consider ventilation, cleaning access and how you use the room.

Ask what the evidence covers

A technical rating such as Rw describes sound insulation under defined test conditions. Ask whether it covers glass alone or a complete window assembly.

A laboratory figure does not promise the same numerical change in your home. The site, noise direction and other sound paths affect the result. Our project recordings demonstrate the change heard on site; they are not certified acoustic tests.

For your first enquiry, send window photos, your property type and the noise source. We can then discuss suitable options.
