Double Glazed Replacement Units
Restore Clarity. Improve Efficiency. Save Money.
Is your glazing misted, foggy, or showing signs of condensation? You don’t always need to replace the entire window or door. At Arnold Installations Limited, we supply and install high-quality double glazed replacement units, restoring your windows to like-new condition—at a fraction of the cost.
What Are Double Glazed Replacement Units?
Double glazed units consist of two panes of glass separated by a sealed air or gas-filled cavity. Over time, seals can fail, allowing moisture to enter—causing the familiar “misted” or “blown” appearance. Our replacement units are made to measure and installed into your existing frames, meaning:
- No need for full window replacement
- Minimal disruption to your property
- A cost-effective, energy-efficient solution
Suitable for All Window & Door Types
We provide replacement double glazed units for:
uPVC windows and doors
Patio and sliding doors
Aluminium systems
Timber frames
Bifold doors
