Quieter rooms. Original windows preserved.
Made-to-measure acoustic secondary glazing for Scottish homes, sash and case windows and period properties.
Make bedrooms and living spaces more comfortable beside busy roads.
Road noise and existing windows
Traffic noise includes low-frequency engine sounds and higher-frequency tyre and road sounds. Different windows and noise sources require different acoustic approaches.
Seals, cavities and glass
An effective installation considers airtightness, cavity depth and glass selection together. Simply using thicker glass is not always the best solution.
Keeping your existing sash windows
Secondary glazing can be fitted on the room side of original windows, subject to suitability and survey. This can be attractive in traditional homes where retaining character matters.
What to expect
We can discuss likely improvements and available product test data, but cannot promise silence or a particular in-room decibel reduction without appropriate assessment.

Technical guide: selecting acoustic glazing for your property
Why Rw + Ctr matters for road traffic
Traffic includes lower-frequency energy that may not be represented well by a single headline Rw figure. Where available, compare manufacturer Rw + Ctr values for the specific tested assembly and discuss the nature of the road noise during the survey.
Understanding acoustic glazing test figures
Manufacturers may quote Rw, a laboratory weighted sound reduction index in decibels. Rw + C and Rw + Ctr are spectrum-adapted ratings; Ctr is especially relevant when assessing noise containing more low-frequency energy, such as road traffic. These values are not a promise of the decibel reduction measured inside an occupied room.
What determines the finished result?
The original window, the separation between the panes, glazing composition, perimeter seals and installation detailing all affect acoustic performance. Air leakage and sound passing through vents, walls or adjoining construction can limit the benefit. The right solution is chosen for the complete window and the actual noise source, not by glass thickness alone.
