This removes rattles and lowers heat loss by up to 30%.Slim-Profile Double Glazing: It is now possible to fit "slim-lite" double-glazed systems into existing lumber sashes. These systems have an extremely thin profile (frequently 12mm overall density) and fill the space with Krypton or Xenon gas to offer insulation equivalent to modern-day windows.Secondary Glazing: For Grade I or II noted structures where the glass can not be changed, a discreet internal glass secondary pane can be set up.
