Hi Chuck and all TT'ers around the globe,
Go to your nearest building supply house (home depot etc). They have some of
that expanding urathane (sp) foam in spray cans. Builders use them to insulate
around windows in new construction. You just spray it in and it expands and
conforms to the hole and anything in it. I've used it but cant think of
the brand name. Hope this lead pans out for you.

Subject: [TowerTalk] Is expanding insulating foam safe to use
I was wondering if expanding insulating foam is safe to use around
coax cables. I remodeling my basement and can cut out about 100'
of coax by going through an exterior wall. Problem is how do I seal
up the hole. I put some coax cables in a can and filled it with
Great Stuff expanding foam for about a week and the cable jacket
looks wet but see no major degradation. I do know that caulking
compunds that smell like vineger will run the cable over time. Since
I do not desire to tear up the drywall I would like to make sure I do
it right the first time.
Please respond directly to me since I am not currently subscribed to
Thanks for all your help in advance!!
