Restoration vs. Replacement: Making the Right Choice

Enhancing Energy Efficiency
Historically, sash windows were infamous for being draughty and thermally inefficient. However, modern engineering has changed their efficiency. A professional business focuses on several key locations to enhance energy scores:
- Vacuum Glazing: A development where a microscopic gap between two panes of glass provides the insulation of triple glazing with the density of a single pane. This is perfect for heritage properties where thin frames are necessary.
- Low-E Glass: Coated glass that shows heat back into the space.
- Inert Gas Fillings: Using Argon or Krypton gas between panes to reduce thermal transfer.
Upkeep Tips for Longevity
To make sure the financial investment in sash windows lasts for decades, a constant maintenance schedule is needed.
- Annual Inspection: Check for fractures in the paintwork, as wetness ingress is the main cause of rot.
