Living above the Tube or near a railway? Learn what glazing can (and can't) do for underground noise and vibration, plus complementary solutions.
London's Underground network passes beneath thousands of homes, and while living near a Tube station has obvious benefits, the noise and vibration can be challenging. If you're affected by railway noise, it's important to understand what window treatments can address—and what requires different solutions.
Railway noise reaches your home through two distinct paths, and they require different treatments:
Sound travelling through the air from:
Windows CAN help significantly with airborne sound.
Vibration transmitted through the ground and building structure from:
Windows have LIMITED effect on structure-borne sound.
Understanding this distinction is crucial for setting realistic expectations and choosing appropriate solutions.
For surface-level railway noise—the rumble of trains, squealing brakes, station announcements—secondary glazing works extremely well. The principles are identical to traffic noise reduction:
| Scenario | Without Secondary Glazing | With Acoustic Secondary Glazing |
|---|---|---|
| House 30m from railway | 65-72dB during pass-by | 28-35dB during pass-by |
| Flat near station | 60-68dB ambient | 25-32dB ambient |
| Near level crossing | 70-78dB events | 32-40dB events |
These reductions are comparable to what we achieve for traffic and aircraft noise—life-changing improvements for residents.
Underground railway noise is more complex because much of it reaches you through the building itself, not through the windows.
When your walls and floors are essentially speakers, improving the windows addresses only part of the sound path.

Underground railway noise is more complex because much of it reaches you through the building itself, not through the windows.
When your walls and floors are essentially speakers, improving the windows addresses only part of the sound path.
Even when vibration is the primary issue, secondary glazing helps in several ways:
Some underground noise does travel through air—through ventilation shafts, station entrances, and gaps in the building envelope. Secondary glazing blocks this pathway.
Vibration often causes windows to rattle in their frames, amplifying the perceived noise. Secondary glazing, independently mounted, doesn't rattle and adds mass that dampens original window movement.
By addressing the windows—often the weakest acoustic element—you reduce the total noise load even if some vibration-transmitted sound remains.
Secondary glazing forms part of a comprehensive approach, working alongside other measures to achieve meaningful improvement.
For properties directly above or adjacent to Tube lines, secondary glazing alone typically achieves:
This is meaningful but may not eliminate awareness of trains entirely. For that, additional structure-borne noise treatment is needed.
If underground vibration is severe, consider these additional measures:
A resilient layer beneath flooring decouples the floor surface from structural vibration. Options include:
Cost: £40-£150 per m², plus flooring replacement
Walls can be lined with isolated plasterboard on resilient mounts, breaking the vibration path to wall surfaces.
Cost: £100-£200 per m² of wall treated
Suspended ceilings with resilient hangers reduce re-radiation from ceiling surfaces.
Cost: £80-£150 per m²
The most effective approach creates a structurally isolated room within the existing room. All surfaces (floor, walls, ceiling) are decoupled from the building structure.
Cost: £400-£800 per m² of room treated
This is expensive and reduces room dimensions, but achieves the greatest vibration isolation.
For most Tube-affected properties, we recommend:
Many residents find secondary glazing alone provides sufficient improvement for comfortable living, especially if combined with strategic furniture placement (heavy bookcases on affected walls, for instance).
Certain Tube lines and sections cause more disturbance due to tunnel depth, construction method, or train type:
