uPVC sliding sash windows for Lisburn jobs
Sliding sash windows are made around the balances, so we size each window individually and choose the balance to suit the sash weight, including any acoustic or toughened glass you specify.
Most vertical sliders are ordered as straight replacements for timber box sashes. If the originals have horns, glazing bars or a particular meeting-rail height, note it on your schedule and the new windows are made to match.
- Spiral or constant-force balances sized to sash weight
- Double glazed sealed units, with heritage spacer colours
- Twin sashes sliding vertically in a uPVC box frame
- Sash locks, sash lifts and restrictors
