We also do not have termites like the USA does. Infestation of these panels

At this time. The Americans did not used to have fire ants, Hobo spiders
and a number of other pests, but they now do. I believed the uk didn't
have dangerous spiders, until my wife was bitten by a Hobo spider a few
weeks ago. Not recommended.
I would expect my local ant population to infest this type of
construction within 20 years and excavate some very large holes.
