Restoration vs. Replacement: Making the Right Choice

• Inert Gas Fillings: Using Argon or Krypton gas between panes to lower thermal transfer.

Upkeep Tips for Longevity

To guarantee the financial investment in sash windows lasts for years, a consistent upkeep schedule is required.

• Yearly Inspection: Check for cracks in the paintwork, as moisture ingress is the main reason for rot.
