- Inert Gas Fillings: Using Argon or Krypton gas between panes to decrease thermal transfer.
Upkeep Tips for Longevity
To guarantee the investment in sash windows lasts for years, a constant maintenance schedule is needed.
- Yearly Inspection: Check for cracks in the paintwork, as wetness ingress is the primary cause of rot.
