Stop Traffic Noise: Residential Secondary Glazing London
Transform your home into a peaceful sanctuary with our professional secondary glazing solutions. Achieve up to 80% noise reduction while improving thermal efficiency and preserving your property's character.
How Our Residential Glazing Blocks Traffic & Aircraft Noise
London's A-roads, Heathrow flight paths, and 24/7 urban activity mean your home is under constant acoustic assault. Our residential secondary glazing creates a precision-engineered sound barrier using 10.8mm acoustic laminate glass specifications for London homesand a 100–200mm de-coupled air gap—blocking up to 54dB of traffic and aircraft noise without altering your original windows.
Unlike replacement windows, secondary glazing adds a discreet internal window that works with your existing frames. This approach is particularly valuable for period properties, listed buildings, and conservation areas where external alterations are restricted.
Our systems achieve 45–54 dB measured noise reduction versus standard double glazing—significantly outperforming standard double glazing. Whether you're near a busy road, under a flight path, or simply want a quieter bedroom, we have solutions tailored to your specific requirements.
Beyond noise reduction, secondary glazing creates an insulating air gap that dramatically improves thermal performance and U-value efficiency. Expect up to 65% reduction in heat loss, lower energy bills, and elimination of draughts and condensation on your original windows.
