A typical criticism of Victorian sash windows is that they are "cold and draughty." However, modern remediation methods have actually resolved these concerns without jeopardizing the window's look.
Draught-Proofing: Specialized brush strips can be routed into the conference rails and personnel beads. This eliminates rattles and reduces heat loss by as much as 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed units into existing timber sashes. These systems have a really thin profile (typically 12mm overall thickness) and fill the space with Krypton or Xenon gas to provide insulation comparable to modern-day windows.Secondary Glazing: For Grade I or II listed buildings where the glass can not be changed, a discreet internal glass secondary pane can be set up.
