I realize it is coming on summer time, but .. while the weather is good...
The place I am in is a 70's duplex with metal windows. When it is cold at
night, you can feel
the cold air coming in through the windows. Is there a way to seal these
windows? Something like weather stripping? Same for a sliding glass door. We
have sliding glass door in a bedroom, that is also metal, and also of the
70's late 80's. You can feel the cold air coming in through that door also.
Can it be sealed up, with something like weather stripping? Replacing the
windows/door isn't an option... Any ideas would be greatly appreciated.
the movement of cold air when the air is cooled by the glass and frame and
then falls having become more dense than the surrounding air. This type of
current can be amazingly strong if there is a big temperature difference and
the window has a very low R factor -- like single pane glass and a metal
frame. I'm sure that there are some websites that describe the methods for
tracking down air leaks and of course there are companies that offer the
service. If there are detectable leaks then relatively simple fixes like
weather stripping and caulking may help you repair them without paying a
I have used 3m window film on my metal
paned windows and it is great, cheap,
keeps drafts out and lasts until the clear
tape lets go about 4 months. It is shrink
wrap material, clear and is invisible when
applied correctly. Look at Home Depot.
<< I thought about using plastic on the Windows during the Winter months, on
the outside, but I'd rather not (for the curb appeal) >>
Curb appeal? You'd rather throw money at your fuel supplier than have some
stranger see your place with energy saving window coverings?
From the single-pane glass/ aluminum frame windows I've seen, the problem isn't
lack of weatherstripping it's the inablity of the window to insulate against
the exterior climate at all.
One pane of glass just doesn't cut it anymore. Of course, it wasn't long after
the energy-crunch of the 70's that they were outlawed in most northern climates
yet continued to be installed in more moderate climates, even Florida where
central Air is used like a Northerner would use a furnace.
As for the aluminum, it makes a great conductor too, useless as a window frame
Single Pane Window I think. Mostly a metal frame, with two sliding pieces of
glass on the outside edge, and one large piece of glass in the middle. The
windows have glass on the inside/outside, with the metal spacer between
Yes, exactly like weather stripping. There's actually quite a few
different places where air can seep in through a badly-sealed window
(the 70s was just before energy consciousness reached the building
industry), and they have different solutions, but the most obvious is
going over the existing stripping and finding holes to seal. Our 1970s
aluminum storms used felt stripping, and it's badly deteriorating. The
storms themselves are often out of square, permitting cracks on one side
or another. The sash had a thin felt-like pad bumping up against the
track and this, too, is a place where air can creep in.
Weatherstrip at least the edge of each sash. Make sure you seal the
place where the two sashes touch, as well. You can use different
materials depending on expense and what will fit or attach easily. Some
have shorter lifetimes than others!
All of this is beside the problem that the window *frame* is a place
where a lot of air can sneak past. Caulking on the inside *and* outside,
along all joints, will most definitely help. There are also methods of
putting insulation into voids in the frame itself, but these are very
dependent on what you have.
Ultimately you'll want to go for the real energy-efficient solution,
which is two panes of glass with something in between. This could be, at
minimum, regular sash inside and storm window outside, or modern vinyl
Same for a sliding glass door. We have sliding glass door
Think of a sliding door as a double-hung sash on its side. The edges
should be weatherstripped the same way.
Replacing may well be worth considering when you contemplate all the
work needed to truly rehabilitate your deteriorating outer skin.
Assuming the windows are 'sliders', remove the sliding side and examine it's
edges. You should find some type of weather stripping embedded in a groove.
If similar to mine, this weather strip material has shrunk from both ends
about an inch gap, plus the material itself has worn down to xxxx.
Remove a short section (an inch long?) being careful to preserve it's shape.
Take your sample to hardware/home improvement center and ask for
matching weather strip.
I found my weather stripping had been 'crimped' into place when the window
was made and would not allow the new material to slide into the groove, so
I used a 'mototool' to grind off the interfering crimp inside the groove.
I assume the fixed pane has similar weather stripping, but have no idea how
get to it???????? Have heard it's easy to break the glass.
It's probably a safe bet the sliding door has similar weather stripping
The trick is figuring out how to get the door out??
Hope this helps.....
