Quieter rooms. Original windows preserved.
Made-to-measure acoustic secondary glazing for Scottish homes, sash and case windows and period properties.
Reduce unwanted outside noise without replacing your original windows.
Why acoustic secondary glazing?
An additional internal glazed layer can improve acoustic separation from road traffic, voices and other external noise. The right design depends on the existing window, the cavity between panes, glass specification and airtight installation. No system removes all sound.
A carefully specified solution
We assess the existing windows, their condition and likely noise sources before recommending a suitable Granada secondary glazing system. Acoustic laminated glass and a suitable cavity may be considered where compatible with the chosen system.
For traditional Scottish buildings
Discreet internal glazing can retain historic timber sash and case windows. Listed building and conservation requirements vary: obtain the relevant permissions before work begins.
What determines acoustic performance?
The overall result depends on glass composition, cavity depth, seals, frame detailing and flanking sound paths. Manufacturer laboratory ratings should not be presented as guaranteed performance in a particular home.

Technical guide: selecting acoustic glazing for your property
Acoustic laminated glass and cavity design
Acoustic laminated glass incorporates an interlayer designed to damp certain vibrations. The glass make-up must be considered alongside the air cavity and the frame seals. A deeper cavity may help in some configurations, but the reveal depth, shutters and access requirements must also be considered.
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.
