How much acoustic reduction can I expect?

Standard double glazing: Rw 30-32dB (still hear most aircraft). Acoustic-spec double glazing: Rw 38-42dB (significant reduction). Premium acoustic triple glazing: Rw 48-52dB (aircraft barely audible indoors).

Will acoustic glazing fund itself through the Gatwick scheme?

If you're inside the Gatwick noise contour boundary: up to £4,300 + VAT contribution. We separate scheme-eligible costs from upgrades clearly so you see exactly what's funded vs your own cost.

Does triple glazing help more than double?

Marginally — acoustic performance depends more on glass thickness asymmetry and laminate content than on the number of panes. Some 28mm acoustic double-glazed units outperform standard triple glazing acoustically.

What about secondary glazing?

Secondary glazing can outperform new sealed units for acoustic if the original window stays — combining original single glazing with an internal acoustic secondary unit at 100-200mm distance gives Rw 42-48dB. Used commonly for listed buildings.

Acoustic double glazing per window: £450-£800 (standard) up to £900-£1,400 (premium acoustic). Acoustic triple glazing: £900-£1,800.

Acoustic Glazing for Flight Paths UK | Heathrow Gatwick Noise

Properties under major UK airport flight paths face constant aircraft noise — peak overflight levels often exceed 75dBA externally, making sleep, conversation, and concentration difficult. S&K Glazing specialises in acoustic glazing for properties affected by aircraft noise. Our specifications achieve up to 52dB Rw noise reduction — equivalent to converting jet overflights into a whisper indoors. We work in all major flight-path corridors including Heathrow, Gatwick, Manchester, Stansted, Luton, Birmingham, and Edinburgh.

Why choose our acoustic glazing for flight paths

Up to 52dB Rw noise reduction — best performance available in residential glazing
Asymmetric panel construction breaks resonance frequencies of aircraft noise
Acoustic-rated laminated interlayers — multiple PVB or SentryGlas layers
Argon-filled cavities tuned for acoustic plus thermal performance
Officially appointed Gatwick Noise Insulation Scheme installer — plus free eligibility checks against Heathrow, Manchester, Stansted, Luton and other UK airport schemes
