Hi there,
This year, after many years of threatening, I finally got a greenhouse.
...The greenhouse is erected on a concrete plinth that
was previously used for an aviary. I felt (rightly or wrongly) that I
needed to do something to insulate the concrete because I though it
would be quite cold.
Psst. Carpet tiles.
Thanks Brian. I'd get that leaky bladder looked at though
