Addition of a second pane of glass or double/triple glazed unit inside an existing window.
Monitoring & feedback recommended: Yes
ADVANTAGES
Can be as effective as/better than replacement energy efficient glazing in traditional windows in reducing heat loss with the advantage that the original window is retained
