Is partial double glazing worthwhile?

Question

My house has single glazed windows. I understand that bubblewrap can act like double glazing, however doing this will ruin my views.

Is there much advantage in only covering part of the Windows (say 50% - the parts behind the curtains and close to the floor)? Im interested both from a power saving and "crying Windows" POV.

Are there any other "low cost", fairly easy ways to improve my window insulation which do not require modifying window frames that I can do myself with only basic skills? Getting this professionally done would not seem to make sense from a cost POV.

Answer 1

You can DIY install low-e (low-emittance) storm windows that retain the views and dramatically reduce window heat loss. There are operable storm windows that don't need to be removed seasonally.
