Window hinge /Friction
main reason a window hinge or friction stay needs replacing
is when the black or grey friction block on the window
hinge breaks in two. See picture below.
reasons window hinges or friction stays need replacing
when you close your window you can feel a draught along
or down the hinge side of the window
2) when you close your window the window does not pull
in at the top or down the side of the window.
3) A rivet may have broken from the window hinge leaving
the window unable to be closed.
4) with larger windows the hinges can bend and buckle
when you try to close the window leaving the window
impossible to close.
note that although your window hinges seem to work properly
if you are feeling draughts through the window when
it is in the closed position then it is almost certainly
the window hinges that are worn. A good test is to use
a credit card , if the card can slide easily between
the opening vent and the rubber gasket on the outer
frame the the window hinges are almost certainly worn.
do I know which window hinge I need ?
You will need to measure the length of the window hinge
that is fitted to the outer frame (i.e. the part of
the window hinge the friction block slides along shown
in the picture above).The window hinge sizes available
are 8 , 10, 12, 16, 20 or 24 inches long or 205mm ,
255mm , 305mm , 410mm , 510mm , 610mm.
In the past there were varying widths of window hinges
from 14mm to 18mm , nowadays the vast majority are 18mm
with the odd window hinge 17mm wide classed as a slim
line window hinge.
The window hinge normally sits in a channel on the outer
frame 18mm wide however because of the hundreds of different
upvc profiles manufactured over the years some of the
early profiles had a channel less than 18mm. If the
channel on your windows is less than 18mm then there
will almost certainly be a upvc rib which can easily
be chiselled off allowing the new window hinges to sit
in the right position.
easy is it to fit new window hinges?
you need to remove the window hinges from the outer
frame either by unscrewing the existing screws or drilling
off the rivet heads if they were riveted to the window
frame.You then pull the opening window vent out of the
frame as shown in the picture above. You will have the
opening window vent with the 2 window hinges attached.
You then need to mark the existing position of the window
hinges attached to the vent as shown below.
with a pencil where the existing window hinge is positioned
, you will see a horizontal line where the hinge is
cranked.If the hinge is plastic at the at the top mark
where the plastic ends.This is critical as the top point
of the hinge must protrude from the window vent exactly
the same amount when you fit the new window hinges.
the existing screws or drill off the rivet heads to
remove the old hinge as shown below.
the new hinge onto the window frame as show below.
the hinge is lined up with the pencil mark as shown
above screw the hinge onto the window vent.
the window vent with the to new window hinges back into
its opening as shown below.Normally the window hinges
need to be positioned as high as they can in the channel
, sometimes they are positioned slightly different.This
should be noted before taking the vent out .
the new window hinges with self tapping screws .Two
of the holes in each window hinge will be elongated
allowing the window vent to be moved up or down slightly.When
the window hinges are in the correct position screw
a self tapper screw into the final hole to hold in position.
