SOME insulating glass units have argon gas, but they are in the minority. What
insulates an insulating glass unit is the dead air space between the two pieces
of glass.
My 40 years experience in the glass business tells me to strongly NOT try and
drill thru an insulated glass unit as 1. it will destroy the air seal and allow
condensation and loose insulating value, 2. it is extremely difficult for even
a professional craftsman to drill thru the two pieces of glass in an insulating
unit without breakage,,,
Why not use one of the MFJ window panels? They allow you to cut to size and
come with foam tape to close off the edges.

If you drill through the new, energy efficient double window pane you will let
the argon gas between the panes leak out. This gas is what provides the
increased R value for the space between the panes. Caveat Amateur.

When I was living in Virginia, this worked excellent for me:
At your local hardware store, find a bathroom tile hole cutter the size that
your feed-thru insulators requires. Lay your double pane windows down on an
old towel. Install the tile hole cutter in your electric drill to cut the
holes. Do not press down on the drill but just use the weight of the drill
itself to cut the hole, with the drill running at a very SLOW speed. If you
do this carefully you can cut the holes and then install your insulators,
the key is to NOT PRESS DOWN ON YOUR DRILL and you will not break the glass.
Of course when it is time to sell your home, you wish remove the window and
get that glass replaced. This worked very well for me!

Subject: [TowerTalk] New windows versus my antenna wiring
Hi all,
I have one open wire feeder and a couple of coaxial cables coming into my
basement radio shack. Many years ago I removed the glass from the top pane
of a window and replaced the glass with plexiglass. I drilled the plexiglass
for feed thru insulators for the open wire and holes for the coaxial cables.
I would like to replace the 5 windows on that side of the house, which
includes the window with the plexiglass antenna cable entrances. The
existing wooden-frame windows with a single pane of glass will be replaced
with double-paned, energy efficient double-hung windows.
How do I get my antenna wires into the house after the newer windows are
installed? The newer windows do not lend themselves to the plexiglass scheme
in use with the existing window. I would prefer not to drill holes in the
basement wall -- I want to sell this house eventually (that's one reason for
replacing the windows in the first place).
One thought I had is to lower the upper half of the new window about a foot
and insert a piece of plexiglass at the top of the window. Buttress the
upper half of the new window up against the plexiglass. Seal as necessary
with polyurethane foam insulation. One problem with that idea is that the
upper section of the window can be lowered from the outside
-- not very secure.
Any ideas as to how to get my open wire feeder and a few coaxial cables
through the wall after the new windows are installed while not damaging the
walls of the house or the new window?
Thanks.
Steve, K8JQ
