I am buying a steel shed , it has insulation(kingspan) on the inside .. if I
apply treated plywood as the base would I still get condensation ? The shed is
only 7ftx8ft. Please help


Help is here - never worry .

1. a structure that is 7 x 8 feet is not a shed.
.. it's barely a closet
2. a structure that is 7 x 8 feet is not steel
.. it's tin
3. a structure that is 7 x 8 feet might well benefit from
a stable base of patio stones. - never wood.

Most people think that moisture comes from the ground -
when it's actually in the air - all around us.
