I'm now going to show you how to install a timber sash window.
We use this in the bedrooms like this so that we can allow both panes to come up and down
for maximum ventilation.
The tools we're going to use for this job are plastic flashing, a drill set, some glasses,
a craft knife, some screws, a tape, packers, pencil, a staple gun, and a battery drill
and level.
Because we are in such a confined area inside this bedroom, it's advisable to position the
window in this position here, because of that space problem we have.
I'm now going to roll the flashing tape out and staple it on to the bottom of the sill.
We use this flashing, quite simply, just to allow any extra moisture that may get in to
escape outside.
I'm now going to trim the end of the flashing.
We're now going to staple the flashing to the bottom of the window and wrap around the
bottom of the sill also.
All right.
Now the flashing is all stapled on, we're going to tidy up the corners just by doing
a nice fold and keeping it out of the road of the frame.
Its now time to put the window in position.
But first, we're going to drill our pilot holes while the window is on the ground, as
this is sometimes easier, instead of doing it in position because of the height.
It is advisable to remove the beading like this from the jamb.
This allows us maximum fixing into our frame with our screws and also, when you put the
bead back, covers the screws up to save any filling later on.
We're now marking our pilot holes approximately 75 millimeters up from the sill and down from
the top jamb.
Also measuring in 35 to 40 millimeters inside from the edge of the jamb.
This will allow our screws to be covered from the bead.
I'll now repeat the process on the other side.
To drill the pilot holes, we are going to use a battery drill and a four-millimeter
drill bit.
I'm also going to lift the sash window up from the bottom so that the drill doesn't
damage the timber sash.
The holes are drilled.
Now it's time to put our window in position.
I'm just now going to replace the sash back into its original position.
This will save it falling out.
Because this is a heavy lift, I am going to use my mate Matt to give me a hand to lift
the window into place.
Now the window is in place, we're going to make sure that we check the levelness of the
window and also the side jambs to make sure they're plumb.
We use this using our spirit level.
Yep, that's great.
This corner is actually in the right position.
But to allow me to screw it properly, I'll lift the sash slightly up again so I don't
damage the sash with the drill.
One other thing we need to check also is to make sure that the window jamb is flushed
with the plaster wall inside the lining.
We can use our packer to do this by simply checking like that.
We'll now check that the window is plumb.
This window is showing it needs to move ever so slightly this way, so we'll adjust our
packers to suit and screw it into position.
For packing the top, we're using a three-millimeter masonite packer.
We are now positioning the window in the correct place, nice and flush with our plaster board,
and the masonite packer in line with the screw.
It's also advisable that the screw heads are slightly below the surface.
This allows room for filling ready to paint the window.
We now check our jamb for plumb, and that's exactly where we want the window.
We now finish the other side off as well.
I've now completed screwing off the window.
And our last step is to replace the bead that we removed earlier on the sash side of the
jamb.
This will secure the sash in place.
Great, job is complete.
The sash and the window are working as they are expected to be.
