Retrofit Double Glazing
Specialists now use "slim-lite" double-glazed units. These systems have a very narrow cavity filled with insulating gases like Krypton or Xenon. Since they are so thin, they can be suited the initial Custom Sash Windows frames, keeping the fragile profile of the glazing bars that define the window's character.
