Secondary Glazing Wandsworth | Clapham Junction & Railway Noise Specialists
Wandsworth is home to Clapham Junction — Britain's busiest railway station — with over 2,000 trains daily generating near-constant rail noise across SW11, SW18, and SW17. Combined with A3 and A205 South Circular traffic, Wandsworth's Victorian terraces need specialist acoustic treatment. Our 10.8mm laminate glass delivers up to 54dB reduction.
Wandsworth Noise Challenges
Clapham Junction Rail Noise
Over 2,000 trains per day pass through Clapham Junction from 5am to 1am. Properties within 200m experience 68-75dB of combined wheel-on-rail screech, braking noise, and platform announcements. Our secondary glazing with wide air gaps specifically targets the 1-4kHz frequency range of rail noise.
A-Road Traffic & Battersea
The A3 and South Circular (A205) create a noise corridor through the borough. Battersea's ongoing regeneration around the Power Station adds construction noise. Wandsworth High Street and Trinity Road carry heavy bus and HGV traffic throughout the day.
