Sash Window Secondary Glazing

Period sash windows look beautiful but rattle, draught and lose heat. Vertically sliding secondary glazing matches the movement of the original sash, so you keep full use of the window while adding warmth and cutting noise — all without touching the historic joinery.

  • Vertical slide matches the original sash
  • Full use of the window retained

How long does it take to fit sash window secondary glazing?

Most sash window secondary glazing installations take from a single day to a few days depending on quantity and access. We confirm exact lead times and the fitting date in writing before work starts, and tidy up fully on completion.
