[Greenbuilding] Door frames and gaskets

[bill.allen at verizon.net]

Thanks for the suggestions.

I have been trying to picture/design the "close on top" door but haven't come up with a good solution yet.  The devil is in the details...if anyone can point me to any examples I could use as a model, I would really appreciate it.

Can't add any additional space so the mud room idea won't work.

I do plan to have a storm door so that will help a little.

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?
