Slimline double glazed replacement sashes are the smart way to warm up Redland homes while keeping original frames and period looks. If your box frames are sound, swapping only the sashes is faster, cleaner and more economical than full replacement.
What this upgrade includes:
- Bespoke timber sashes (often Accoya®) made to measure
- Slimline double glazed units that keep historic sightlines
- Brush-seal draught proofing integrated during installation
- Rebaling of weights; lubricated pulleys; smooth travel
- Profile-matched glazing bars, horns and mouldings
Why Redland homeowners choose this:
- Lower cost than full window replacement
- Retain external appearance for conservation sensitives
- Significant thermal and acoustic improvement
- Rapid installation with minimal disruption
We advise on listed/conservation constraints where relevant.
