Thusly spake Pat: "......there are two types of expanding foam in a can,
the stuff you used, and a minimally expanding foam intended for around
doors and windows so things don't get pushed out."
Yea, I (obviously) learned this the hard way. As this is our first house
bought (about six years ago with the below mentioned foam fiasco about
five years ago) I was even more cluseless than I am now.
I now revert to an old signature that I often wonder... should it still
be in constant use?
Still clueless but always learning
