3-Panel Horizontal Slider Secondary Glazing made to measure for Watford, Hertfordshire. Three horizontally-sliding panels — ideal for wide openings where two panels would be too narrow.
Best for: wide openings and bay windows.
Watford sits roughly 2.2 miles from the M25, so homes here often deal with steady background noise from delivery and bus traffic 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.
