Flipping through the "vast wasteland"[1], now and again I run across a
commercial that catches my attention. The Twin Draft Guard was one such.
Looks like an actual Good Idea, to keep air from infiltrating in/out of
your house through doors.

Anyone have any actual experience with this modern miracle product?

me)


[1] Anyone who remembers this reference from when it was first used is
dating themselves.

In 1940 my dad designed a door seal that was automatic. The door had a
routed out area in the bottom. In it was a felt seal that was driven tight
to the floor by a cam action actuated by a rod that was pushed in on the
hinge side as the door was closed. worked great. ww



I've installed a lot of door sweeps on automatic doors. The things
look like a long brush. Here's a link to the C.R. Laurence Co., Inc.
web page of door sweeps and there is an automatic retracting sweep
listed there too with the brush type and others.

I've purchased and used a lot of their products over the years and
CRL is an excellent source for parts, tools and materials for glass
working, windows and entrances of all types.
