| Upkeep | Requires routine repainting or re-staining. | Low upkeep; wipe-clean just. |
| Ecological Impact | Sustainable if FSC-certified; biodegradable. | Recyclable, however involves chemical production. |

- Vacuum Glazing: A development where a tiny space between 2 panes of glass offers the insulation of triple glazing with the density of a single pane. This is ideal for heritage residential or commercial properties where thin frames are obligatory.
- Low-E Glass: Coated glass that shows heat back into the room.
- Inert Gas Fillings: Using Argon or Krypton gas between panes to minimize thermal transfer.
Maintenance Tips for Longevity
To guarantee the investment in sash windows lasts for decades, a consistent upkeep schedule is needed.
- Annual Inspection: Check for fractures in the paintwork, as moisture ingress is the primary reason for rot.
