Repair vs. Replacement: Making the Right Choice
A trusted sliding sash window company will normally use 2 paths: restoration of existing frames or full replacement.

- Vacuum Glazing: A development where a tiny space between two panes of glass offers the insulation of triple glazing with the thickness of a single pane. This is ideal for heritage homes where thin frames are compulsory.
- Low-E Glass: Coated glass that reflects heat back into the space.
- Inert Gas Fillings: Using Argon or Krypton gas between panes to reduce thermal transfer.
Maintenance Tips for Longevity
To ensure the financial investment in sash windows lasts for years, a consistent maintenance schedule is needed.
- Annual Inspection: Check for fractures in the paintwork, as moisture ingress is the main cause of rot.
