WHY YOUR PERIOD WINDOWS LEAK HEAT

Original Victorian and Georgian sashes were never designed for central heating. Over time, gaps form around frames, pulleys and meeting rails, causing:

  • Cold draughts at ankle height.
  • Whistling and rattling on windy nights.
  • 25 %–30 % of total heat loss in many sandstone tenements (Energy Saving Trust).
