Key Takeaway:

Acoustic glass can help, but it’s rarely the silver bullet. The best results come from a layered approach that tackles all the ways noise sneaks into your home.

Next Steps You Can Try:

• Seal the gaps – around window frames, vents, and trickle vents. Even small gaps let in big noise.

• Test with low-cost fixes – hang heavy curtains, blankets, or acoustic liners to see the difference before investing.

• Upgrade insulation – denser loft and cavity wall insulation (e.g. mineral wool or rockwool) helps with airborne noise.

• Consider secondary glazing – often more effective than replacing windows, thanks to the extra air gap.

• Look at shutters – roller or folding shutters can add both thermal and acoustic protection, especially at night.

• Combine solutions – no single product “soundproofs” a room, but layering strategies can make traffic noise far more tolerable.
