Plexiglass windows

Pretty pleased with myself today.  I got the plexiglass attached to the cattery windows for the winter season.

These are on the outside of the louvre windows in the front half of the cattery, where the new ceiling and insulation is.  it makes the windows there effectively double glazed (not quite as good as commercial ones!) and should make it much less draughty, and more efficient to heat in winter.  The plexiglass is removable for summer, letting us take advantage of the louvres for airflow in the hotter months.
