2. Windows

Window glazing

Window glazing When we moved in, some windows in the house had secondary glazing. That means the original window had another pane of glass about 12cm behind it. This was pretty good at keeping the draughts out, but double-glazing is better because it reduces conduction and convection between the panes.

We changed our single-glazed windows for
double-glazed windows made with wooden
timber frames. Timber frames are more
sustainable than aluminium frames (these
use a lot of energy to manufacture) and PVC
frames (these can get brittle in the sun's UV
light and crack in use, which means they can
need replacing sooner).
