I have a large number of lengths (6 - 8 ft) of veneered chipboard. I have
to temporarily clear out the rooms where they are used as shelving but can't
for various boring reasons store them elsewhere in the house. How much, if
at all, would they suffer if stored in the open, raised off the ground and
covered with thick plastic sheeting? Ideally I'd like to be able to reuse
most, perhaps all, of them again.

I anticipate that the chipboard would be outside for something like six to
eight weeks.

Many thanks for any thoughts.
