| Maintenance | Needs regular repainting or re-staining. | Low maintenance; wipe-clean just. |
| Ecological Impact | Sustainable if FSC-certified; biodegradable. | Recyclable, but includes chemical production. |

- Vacuum Glazing: An innovation where a microscopic space between 2 panes of glass supplies the insulation of triple glazing with the thickness of a single pane. This is ideal for heritage properties where thin frames are obligatory.
- Low-E Glass: Coated glass that shows heat back into the space.
- Inert Gas Fillings: Using Argon or Krypton gas in between panes to lower thermal transfer.
Upkeep Tips for Longevity
To ensure the financial investment in sash windows lasts for decades, a consistent maintenance schedule is needed.
- Annual Inspection: Check for cracks in the paintwork, as wetness ingress is the main reason for rot.
