Repair vs. Replacement: Making the Right Choice

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

Maintenance Tips for Longevity

To ensure the investment in sash windows lasts for years, a constant maintenance schedule is needed.

  • Annual Inspection: Check for cracks in the paintwork, as wetness ingress is the primary reason for rot.
