Balanced Vertical Slider Secondary Glazing made to measure for Gelligaer, Caerphilly. Vertical sliding units designed to accompany sash windows. Self-supporting panes stay in place at any chosen position.
Best for: traditional and listed sash windows.
Gelligaer sits roughly 7.1 miles from the M4, so homes here often deal with steady background noise from commuter 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.
