INSTALLING A VERTICAL SLIDER IN 7 SIMPLE STEPS
Have you ever experienced difficulties when installing vertical sliding sash windows? The
experts at Synseal Group talk you through the best practice for installing an Evolve VS.
1.
It might be an obvious point to make, but
make sure the aperture you’re fitting the
window into is square. We recommend
measuring the diagonal as well as the width
and height of both the window and the
aperture for a perfect fit.
Top tip! Vertical sliders must be stored
upright to prevent the frame from
bowing. Large frames may barrel slightly
before installation, but this is normal and
is corrected when the frame has been
installed.
Fix the cleats 150mm from each of the corners
with 20mm self-drilling screws, with the gap
between two fixings not exceeding 600mm.
If you have a wider gap you’ll need to fit
additional cleats along the width and height of
the window. We suggest using the back edge of
the window for retrofits into plaster, or tapping
in to the middle of the frame for new builds.

3. 4.
Fit the end caps using super glue, and
tapping into place with a rubber mallet. Place packers onto the surface of the
aperture or sit the window on a mortar bed
but check the surface is level before lifting
the frame into place.
Check the window is square and level then drill the cleats into place
– watch out for the centre cleats though, as drilling these in too far
can open up the gap between the sash and the frame. We recommend
putting side packers in place before drilling to prevent this.
Top tip! We don’t recommend using expanding foam for installing
vertical sliders. However if this is your preferred method, we suggest
placing a packer between the sash and the frame and leaving it until the
foam has set to help prevent bowing.

6.
Mark and drill holes for the pole eye handles before
screwing in place. We recommend installing them on
the top of the upper sash, vertically in-line with the pre-
fixed handles.
