Vacuum Glazing: A development where a tiny gap between two panes of glass supplies the insulation of triple glazing with the thickness of a single pane. This is ideal for heritage residential or commercial properties where thin frames are obligatory. Low-E Glass: Coated glass that reflects heat back into the room. Inert Gas Fillings: Using Argon or Krypton gas between panes to decrease thermal transfer. Upkeep Tips for Longevity To make sure the investment in sash windows lasts for years, a consistent maintenance schedule is needed.
Yearly Inspection: Check for fractures in the paintwork, as moisture ingress is the main cause of rot. Cleaning the Tracks: Ensure the "pockets" and sills are totally free of debris and dirt that can jam the mechanism.
