A typical criticism of Victorian sash windows is that they are “cold and draughty.” Nevertheless, modern-day repair strategies have resolved these issues without jeopardizing the window’s look.
Draught-Proofing: Specialized brush strips can be routed into the meeting rails and personnel beads. This gets rid of rattles and lowers heat loss by approximately 30%.Slim-Profile Double Glazing: It is now possible to fit “slim-lite” double-glazed systems into existing lumber sashes. These units have an extremely thin profile (frequently 12mm overall density) and fill the space with Krypton or Xenon gas to supply insulation similar to contemporary windows.Secondary Glazing: For Grade I or II noted buildings where the glass can not be changed, a discreet internal glass secondary pane can be set up.
