I’m looking for some information about an odd condition I observed on some plywood siding.
There were horizontal ragged gaps in the siding with some being as long as 4-feet while most others were much shorter and some being just 1 or 2 ragged small holes. They were mostly random around the perimeter and some were patterned such that they were vertically spaced about 2-feet apart. These areas did not appear, in most cases, to be on the plywood panel seams.
These openings did not appear to penetrate through the siding, just through some of the outer layers.
Any sagely advice would be appreciated.
