- Inert Gas Fillings: Using Argon or Krypton gas in between panes to minimize thermal transfer.
Upkeep Tips for Longevity
To make sure the financial investment in sash windows lasts for years, a consistent upkeep schedule is needed.
- Annual Inspection: Check for cracks in the paintwork, as moisture ingress is the primary cause of rot.
