does kiln drying impart any additional resistance to dry rot

i have some old kiln dried lumber
i think it is fir but might be cedar

it seems to be free of dry rot but i do not know if that is due to
the wood or the kiln drying

Kiln dring makes no difference

Dr Jagels writes a column on wood for Wooden Boat magazine.
I beleive he covered that question not so long ago (altho
more in the context of damp rot), and I beleive the conclusion
was that air dried lumber is more rot resistant.

If you're really curious, you might search back issues of
Wooden Boat.

i wonder if that really applies to all woods

this stuff seems really stable as it is

There is no such thing as "dry rot;" dry wood does not rot. What appears to be dry rot is wood that has been damp or wet at some time, rotted, and then dried. Next time you're in the Egyptian Museum in Cairo see the collection of wood furniture that spent 3,000 years in arid conditions and is still serviceable today.

There is no mechanism by which the technique used to dry wood can affect its resistance to rot. Keep it dry and the microorganisms that cause wood rot cannot survive.

Well, for certain values. Get it above a certain temperature and the
chemistry changes. It won't rot but it will be more dimensionally
stable, more brittle, and less strong.

Actually there is a type of treatment to wood that involves no chemicals
that keeps it from rotting.

There is a "relatively" new process that heats the wood to, IIRC, in
excess of 300 degrees F. This renders the wood unable to be a food
source for mold, mildew, rot, insects, etc.

I saw an article on Pinterest or some such talking about burning, or
heating wood to make it rot and insect resistant, instead of using
pressure treated with chemicals.

Didn't read it but sounded interesting.

The Vikings did so with the ship lumber, nothing is ever really new,
nor safe.

did a tiny bit of research and throughout history charring the exterior
of wood was a technique used as a preservative

it only makes sense in certain applications
