Slimline Hinged Secondary Glazing made to measure for Dunmurry, Lisburn. A super-slim variation of our hinged unit. Single-handle operation, side-hung only — the most discreet opening unit we make.
Best for: narrow reveals, period windows where sightlines must stay minimal.
In Dunmurry, the mix of period and modern housing means owners often want insulation without altering the original frames. Secondary glazing adds a discreet, fully reversible second pane inside the existing frame — cutting heat loss by up to 60% and noise by up to 80%, with no building-regulations approval needed.
