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.
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.
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! 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.
5. 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.
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.
2.
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. Fit the end caps using
Super Glue, and tap
into place with a rubber
mallet.
4. 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.
7. Tidy up and seal the window frame, and the job is done!
