Hi,
I have recently fitted an external wooden door frame that had a draft strip
imbedded in it. This was some sort of synthetic material in a routed groove
all around the perimeter. This compresses when the door closes. Seems to
work well and means that the door is still easy to close. (I have had
problem with stick-on draft strips and badly closing doors in the past...)

It strikes me that I may be able to retro-fit this type of draft-excluder to
the other exterior door to the house. I was thinking of removing the doors
from the hinges, routing a groove in the doors (not the frame) and gluing on
a draft strip. (Rather the same way as an intumescent strip would be fixed.)

Two questions:

1. Where could I buy a strip of draft excluder?
2. Is this a good idea (i.e. is there a better solution, any problems.)

TIA Colin
