Slim-Profile Double Glazing
It is typically possible to retrofit "slim-lite" double-glazed units into initial sash frames. These units are filled with inert gases like Krypton or Xenon, providing the thermal benefits of modern-day glazing without the thickness that would traditionally require a brand-new, bulkier frame.
