VISTAFOLD
ALUMINIUM
VISTAFOLD ALUMINIUM
The Vistafold system is a revolutionary solution for slidingfolding doors developed by the Hillaldam team that has
been taking the industry by storm over the last 15 years.
The system is a complete departure from traditionally
top hung solutions, relying completely on a bottom rolled
concept to minimise the requirement for unsightly, costly
and often impractical overhead support. Available in both
odd and even number panel configurations, it is an easily
adaptable system that is highly weather resistant.
The Vistafold hardware is manufactured from high quality
stainless steel and aluminium components, which are
either anodised or powder coated to give an aesthetically
pleasing and corrosion resistant finish.
VISTAFOLD
THE BENEFITS OF BOTTOM ROLLING
There are a number of major benefits to using the Vistafold
system and the reasons for making a change away from
top hung assemblies is multi-faceted.
The Vistafold systems support the weight of the assembly
from the bottom up, which requires less bulky overhead
support and allows for easier operation – especially on
higher doors. With the door weight taken up by the bottom
track, the perennial problem of sagging lintels is vastly
reduced. This in turn all but eliminates the necessity
for adjustment over the lifespan of the installation. Any
possible deflection of the head opening is accommodated
in the channel depth overhead.
In cases where some adjustment is preferred however,
Hillaldam has an easily adjusted collar-system allowing
up to 5mm of movement.
Whereas top hung systems traditionally have deep bottom
channels that act as dirt and water traps, the relatively
slimline Vistafold track is only 8mm deep and easily
swept out or vacuumed clean.
ADAPTABILITY
Whilst many systems on the market require the
customer to buy specific profiles, Vistafold allows
the use of most standard door and rebate profiles.
This eliminates unnecessary expense and avoids
having to switch materials between swung, straight
sliding and sliding folding systems.
Hillaldam feels that all of these features make the
Vistafold system unique in its design and operation
– we hope you feel the same.
PANEL SIZING
Vistafold is versatile in allowing either an odd number
or an even number of panels as well as a choice of
offset hinge or standard hinge configurations. The easy
calculation sheets make it a simple process to size the
doors no matter which option you choose.
VISTAFOLD
One of the major advantages to the Vistafold system is
that it allows both tracks and overhead channels to be
completely concealed when the doors are closed.
This is a major aesthetic advantage but also assists with
eliminating the build-up of dirt in the bottom track.

CALCULATIONS - UNEVEN PANEL
Where:
PW = Panel Width P = No. of Panels
OW = Opening Width
TF = Thickness of Frame
For an opening using sinkless hinges
A 4mm gap between panels is allowed for and a 7mm gap
between the hinge leaf and the jamb to accommodate the lock.
OW = opening width
P = no. of panels
Panel width (PW) = OW – (2xTF) - (Px4) - 7

NOTE:
A 8mm gap between panels is allowed for and a 7mm gap
between the hinge leaf and the jamb to accommodate the lock. Cutout in door stile and roller and guide joint:
Top edge: 10mm deep x 35mm wide (from edge)
OW = opening width P = no. of panels
Top face: 10mm deep x 7mm wide (from edge)
Bottom edge: 42mm high x 33mm wide (from hinge side)
Panel width (PW) = OW – (2xTF) - (Px8) - 7

CALCULATIONS - EVEN PANEL
Where:
PW = Panel Width OW = Opening Width P = No. of Panels
E = No. of End Panels TF = Thickness of Frame
10mm clearance to allow kick of doors
For an opening using cranked hinges and all doors of even width:
PW = OW – (2xTF) – (Px4) - 10
P
For an opening using Non-cranked hinges
where the end door is 12mm longer
PW = OW – (2xTF) – (Px4) – 10 – (12xE)
P
Once you have PW for the non-cranked formula, simply add back
12mm to each end panel to determine its width. EG: For a 2-door
Vista Duo with non-cranked hinges in an opening of 1750mm
NOTE:
Door stiles min 65mm wide
All door leaves equal widths
PW = 1750 – (2x30) – (4x2) – 10 – (12x1)

Cutout in door for bottom roller:
42mm high x 32mm from hinge in door edge
42mm high x 21mm from hinge in door face
= 1660
2
= 830
The door hinged to the jamb is then 830 long and
the door with the end roller 830+12 = 842mm.
Cutout in door for top guide:
9mm high x 32mm from hinge in door edge
