Another window that you'll come across a lot is the awning window. They're the ones that pivot
at the top and wind out at the bottom. Now awning windows most often have gaps down the
sides and the top and occasionally at the bottom. So what happens over time is the timber and the
sash bows. It'll bows the glass as well and then when it winds in it doesn't marry up very well
with the sides of the jam. Another thing that happens with awning windows a lot is that they
are a little bit skewiff and so when you wind it in it may rub on the side of the window frame or
it may actually jam at the bottom. Occasionally the window winders fail as well so look when
you're looking at an awning window consider these things and deal with the function of the window
first before thinking about draught ceiling the window. With awning windows, it's sometimes quite
difficult to determine what the draught ceiling is warranted. So the fly screen is on the inside
and that obscures your vision of the window. If you can take the fly screen off easily then
do so and you'll have a much better look at the window itself however sometimes it's difficult
to get the fly screens off without dealing with the window coverings first. A strong torch is
pretty handy for looking through the fly screen to the actual window sash and window frame itself.
So how do we deal with awning windows? Well the primary way is through draft dodgers for awning
windows. These are draught dodgers fitted with a small black seal. You see this seal doesn't sit
proud of the top of the molding and so it's quite discreet on an awning window especially after the
fly screen goes back on. How these fitted? Well to fit these, the side moldings that exist in the
frame have to be taken off and then the draught dodgers for awning windows are fitted either side
of the window winder and then up the sides. Most importantly the top one fits not to the
window frame but to the top of the window sash itself. So as you wind out the windows sash,
the draft dodger goes with it and as the window sash is closed it comes up and gently meets the
top of the window frame. That's a far preferable action than having the opposite where that is on
the head at the window frame and the and the window sash comes up to meet that.
Occasionally, you'll find window awning windows with massive gaps at the top. These were done
in the 60's and was a way to ventilate the room without the need for window wall vents. So that
was the idea have a massive gap along the top of the awning window then you don't need wall vents.
Of course we don't want the massive gap and so that's another reason for having the draught
dodger fitted to the actual face of the awning sash because that works very well for really
any kind of size gap. Now an alternate way to draught proof awning windows maybe EMV. And I
say maybe for a couple of reasons. So most awning windows have simple pivot hinges at the top and
that leaves plenty of room in the jams for things such as EMV. However some older awning windows
instead of the little pivot hinges at the top they instead have very long sliding hinge mechanisms
along the side and in those cases there's really not enough room for any kind of weather stripping
let alone an EMV. So if that's the case, EMV is out. The other thing that you need to consider
when looking at EMV is having a good look at the gaps down the sides of the windows. You'll need to
do this from outside yeah so you'll need to see that there's at least a two millimeter gap down
each side so that the EMV can function properly in the air without jamming up the window sash
and the same at the bottom. So there needs to be an appropriate gap all around for the EMV to be
operating. The EMV is not terribly good at fitting in the head of the awning window unless you want
to really take the awning window off and fit it but that's quite a bother. And so even if you
fit the EMV around the sides and the bottom, you may want to consider draught dodgers for awning
windows for the heads of the awning windows and then that can be quite well draught sealed again.
Of course make sure that there's an appropriate gap for the EMV. And that's awning windows.
