Welwyn Garden City sits roughly 7.2 miles from the A1(M), so homes here often deal with steady background noise from nearby through-routes and the motorway corridor. Acoustic secondary glazing with a wide internal air gap is the most effective way to cut that low-frequency traffic noise — typically by up to 80% — without replacing your existing windows.
