Notice mold begin to grow at the point of maximum Airflow
This is contrary to the common belief that increasing air flow will solve the problem. It doesn't.
We live in a temperate rain forest where humidity and temperatures are in the
'Goldie Lock Zone' for molds to thrive.
Unprotected wood products that are exposed to outside Temperatures & Humidity are vulnerable to becoming moldy. Recent Provincial building studies have shown that even well built houses with well ventilated attics are increasingly becoming moldy.
These are homes that are built to our regional building codes by
good, conscientious & professional builders.
I encourage contractors, developers, architects & homeowners to read the science.
Because preventing this is far smarter then remediating it.

What the removal of Formaldehydes, & other VOCs mean to Manufactured Wood Products, or MWP
Formaldehydes have been used in the glues & binders of Manufactured Wood Products, like plywood, OSB, & MDF for decades. It gave the glues & binders better performance & helped keep molds from developing. In 1999 Health Canada determined Formaldehydes to be a toxic substance & began legislation to reduce & eventually eliminate it from MWP. Today's MWP are vulnerable to molds under the right conditions. The same conditions of Vancouver Island's Marine Environment.
