Bill,
The weatherstrip trade-named "Q-lon" is available from our area "big
box" stores, mostly as a replacement for OEM weatherstrip, and is
secured in a routed channel by an "arrow strip" along the back edge. It
stays very flexible in low temperatures and has a good bit of flex, to
stay in contact with doors which shift with the seasons. It has a thin
skin and can be damaged by snagging it tearing but is still fairly
durable. I had some with small, surface tears, which still served well
for many years.
Q-lon used to be available in a wood backing, for installation as a
normal aftermarket door weatherstrip, but I haven't seen it for some years.
I like RT's suggestion of a surface mounted and closing door but, on
another tack, what about adding a small airlock chamber/mud room to the
outside of the prime door?
