4-Panel Heavy-Duty Horizontal Slider made to measure for Penderry, Swansea. Heavy-duty four-panel slider for very wide spans with a reinforced frame.
Best for: very wide, high-use openings.
Penderry sits roughly 4.5 miles from the M4, 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.
