Hey group

all this cold weather has me more aware of the shortcomings of my house..

I have what I thought were decent windows. Jeld Wen series D windows,
Wood
with alum cladding.
Double hung, they look nice, the glass is low E I believe, and they
operate
quite well.
Here's the issue, they leak like a sieve.

On the main floor I have 6 on the west side of my house that form 2 bays
they are all 62 inches tall 4 are 22 inches wide and the remaining 2 are
38. On the south side 3 more at 62 x 36 Upstairs I have 5 more at 62 x
36.
There are more on the north and east sides, but they don't catch as much
wind. If there is no wind they are fine but when any wind blows, you
can
feel the cold air blowing coming from the corners of the windows, and
where
the 2 sashes meet along the jamb The horizontal seal between the sashes
is
fine. When I moved in there was a lot of air leaking around the trim and
so
I caulked the trim to the wall which stopped some of the air. I took the
trim off one of the windows and there was insulation between the frame
and
the framing, so I'm assuming that the others are that way, but, I'm not
sold, based on how much air was moving behind the trim.
The bigger issues is the leaking between the sashes and the jambs in the
corners. They seem fine along the length of most of the jamb, but, in
strong wind its really cold in those corners.

The jambs are the compression type that you have to push "out" to allow
the
sash to tilt in, I have used rope caulk (which is easy to remove) to try
and fill some of the gaps but, anytime you move the window, the jambs
compress in a bit, and your gap is back. I'm hesitant to try "real"
caulking there because of that, ( the windows are usually open in summer)
and because I don't want to goop up the windows making them look like
sh&t.

Any recommendations on how to slow the air infiltration?

"Insulation", if it is glass fiber, won't stop air movement.
Foam can seal air leaks better.
Flashing may be part of the problem.
Checking that requires removal exterior trim & perhaps siding.

TB,

you are correct, it is fiberglass pink,
I'm unhappy with my caulking decision now, as thinking about it I should
have foamed the windows right the first time. I think I'll be cutting caulk
and prying trim for the next little while.
However, that still doesn't help the jamb leaking issue. As far as I can
tell, I think its just a really poor design. I'm considering a storm
window pane that would replace the screen window to help knock down the
drafts around the jambs. (not permanent storms) I ran plastic over the
screens to test it out, and it did make a big diff to the air infiltration
issue. Plastic looks like **** though, and is harder to see thru.
