has passed with ease. VPI‘s boards have been developed to suit both Australia and
New Zealand's extreme conditions.
Our products are formulated with careful attention to the UV conditions of the harsh Australian
climate. The extrusion processes we have developed ensure that the colour and UV resistance
are consistent all the way through each product – not just limited to the surface. These features,
presented with clean glossy lines and embossed woodgrain surfaces, bring you products that
deliver years of effective and stylish good looks with minimal upkeep.
All our products come with a complete suite of trims to complement the finished walls. Whether
used for enhancing new work or upgrading existing homes, the results are long-lasting and
eye-catching. We also provide a factory warranty on all products, copy available on request.
This warranty gives full (not pro rata) protection for fifty years. Our cladding is lightweight and
most installations take just a few days with minimum disruption. Maintenance is not demanding
– a quick wash down from time to time will keep the appearance fresh and attractive. A mild
detergent can be used – refer to our care guide for complete information.

Preparation of Sub-Surface (Re-clads and Over-clad only)
Before installing the VPI Vinyl Cladding first remove all shutters, down pipes, cover moulds and
other external obstructions. Nail down all loose boards and flashings. This prevents any pressure
being placed on the cladding from behind once installed.
Remove and replace any damaged studs. Uneven walls should be packed with battening where
necessary to produce an even surface. This will result in an even, regular finish once cladding is
installed.
Installing VPI Vinyl Cladding over Masonry Walls
Using masonry nails, screws or plugs, install 75 wide x 25 deep battens over the entire area to
be clad at 450 mm centers. Battens should also be used around all wall perimeters including
windows, doors, verandas etc. This allows for rigid fixing of trims.
450mm
7Heritage Vinyl Cladding Installation Guide
Basic Rules to follow
These basic rules will ensure the proper installation of solid vinyl products.
1. Fix the cladding at 450mm centres maximum. If your studs are at centres greater than 450mm, VPI recommends the use of ply sheet fixed to the studs. Cladding is then fixed to the ply.
2. Unless indicated otherwise in these instructions, always place the nails in the centre of the nailing slot. Never fasten directly through the VPI Vinyl Cladding. Never fasten too tightly.
3. All higher “J’s” overlap lower “J’s”. All VPI Vinyl Cladding accessories should be overlapped except where noted otherwise.
4. Where boards fit into trims, a 5 millimeter clearance should be left at each end of the board for the normal expansion and contraction. If installation is carried out in high temperatures consideration should be mostly given for contraction. See the section on Allowance for “Expansion and Contraction” for more detail.
5. Ensure all panels are fully interlocked when fastening. See below for more fastening tips:
NAILS: The size of the nail head is very important, as a “fitted” board can be inadvertently lifted off its nail when installing the board, if a nail with too small a head is used. Minimum head diameter 8mm, minimum hardwood frame penetration is 25mm, minimum softwood frame penetration is 35mm, hence fiber cement (fibro) over hardwood house would need a 30 x 2.8mm gal clout. And a fibro over softwood needs a 40mm gal clout. A weatherboard over hardwood would require a 45-50mm gal clout min. NB: Thicker weatherboards need longer fastners.
SCREWS: The size of the screw head is very important, as a “fitted” board can be inadvertently lifted off its screw when installing the board, if a screw with too small a head is used. Minimum head diameter 8mm, minimum hardwood frame penetration is 25mm, minimum softwood frame penetration is 35mm, hence fiber cement (fibro) over hardwood house would need a 30mm x 12Guage Class 4 exterior quality galvanised button head screw. And a fibro over softwood needs a 40mm x 12Guage Class 4 exterior quality galvanised button head screw. For use on Steel Framing, a 30mm x 12 Guage Class 4 exterior quality galvanized button head screw, or similar screw with minimum head dia. of 8mm, should be used A weatherboard over hardwood would require a 45-50mm x 12Guage Class 4 exterior quality galvanised button head screw. NB: Thicker weatherboards need longer screws.
8 Heritage Vinyl Cladding Installation Guide
Nailing / Fastening
Nails should have a corrosion resistant coating with a flat head of 10 millimeters diameter with a shank thickness of no more than 2 millimeters. They must be long enough to penetrate 25 millimeters into a hardwood frame or 35 millimeters into a softwood frame. On VPI Vinyl Cladding and accessories, fit nails back 150 millimeters from the ends when overlapping. IMPORTANT: Cladding
must not be nailed tightly to wall; this will restrict expansion as will nailing at the ends of the slots.
REMINDER: DO NOT NAIL AT THE ENDS OF THE SLOTS.
NO YES
STUD FINDING: On internal corners of house walls, some eave applications, and around doors, windows, meter boxes etc, you will be unable to get fixing onto studs. In these instances satisfactory fixing can be obtained by using the drywall screw with a button or mush head. Be careful not to tighten the screw so that is restricts expansion.
NO SLOTS: Where you are unable to match the trim-nailing slot with a stud, you should use a slot-punching tool to facilitate such. Do not fasten directly through trim.
HOLES: When cutting holes to accommodate plumbing that remains on the wall, the cut that is made to enable the board to go over the pipe should be hidden as best as it can behind the pipe, other wise the cut should be made vertically downwards. If the hole is near the board at the end, a cut can be made along the under side of the step.
9Heritage Vinyl Cladding Installation Guide
Sealant
Sealant is only necessary in areas where water penetration is possible (Pipes or other items that
occur through the solid vinyl cladding.)
A non hardening type preferably the same colour as the siding should be used.
Only approved brands to be used.
OCP 20
Accessories
NOTE: Joins in all accessories with the exception of the starter strip must be overlapped.
Shaded areas represent portions to be cut away for proper overlapping. Cut outs should be 40
millimeters in length with only half of the distance being overlapped (i.e.: 20 millimeters overlap
on a 40 millimeter cut out.)
All materials must be nailed as described in application instructions.
STARTER STRIP
To be nailed at 200 millimeter intervals on the centre of the slot. Do not overlap.

12 Heritage Vinyl Cladding Installation Guide
Storage & Handling of VPI Vinyl Cladding
It is recommended that both handling and installation is carried out by two people.
When in storage, boards must be laid flat in the original packaging directly on level ground out of
the way of passing traffic and where practical out of direct sunlight.
When removing the boards from packaging, cut through full length of external packaging and lift out.
Before commencing the task - IMPORTANT
It is necessary to compensate for natural horizontal expansion and contraction of the VPI
Vinyl Cladding. As a general rule expansion can be confined to 1 mm per lineal meter, but
read carefully the section on “Allowance for Expansion & Contraction” Vertical expansion is
insignificant and need not be compensated for.
Allowance for Expansion and Contraction
It is important that allowance is made for the natural expansion and contraction due to the
ambient temperature variation of Heritage Board.
As a rule, allow 5 millimeter clearance at each end of the board (a 10 millimeter total), but refer
to the table below for extra allowance due to extreme weather.
12
Ambient Temperature on Day of Fitting Total Clearance to Allow in Millimeters
0°C 2.0 mm per lineal meter of board length + 10mm
10°C 1.5 mm per lineal meter of board length + 10mm
20°C 1.0 mm per lineal meter of board length + 10mm

13Heritage Vinyl Cladding Installation Guide
Installation of Boards
STARTER STRIP
The Starter Strip must be straight, level and line up at the corners as this will determine whether
the boards will line up on corresponding walls. Check the whole building to ascertain at which
level the siding will be started. Measure the width of the starter strip from the lowest point. This
will be the level at which the chalk line will be set to mark the top edge of the starter strip.
LOWEST CORNER
Using a water level, establish the corresponding point at the other end of the wall marking it with
the chalk line then fix the starter strip. Repeat this on all other walls ensuring all corners match
up and the last line matches the first line. When fixing the starter strip it should be stopped
short of all corners to allow fixing of the corner post. Approximately 75 to 100 millimeters is
acceptable.
ALTERNATIVE METHOD
If the house is out of level more than can be compensated for by the starter strip width,
sometimes it is appropriate to set the starter strip parallel to the existing wall level. The reason for
this is if the wall height is consistent and the bottom board is cut with a taper to start off with,
then the windows which will have drooped with the wall will not be parallel to the siding and the
top board will also need to be cut on a taper thus making the whole wall look crooked as it is. If
it is done parallel to existing, the droop will not be particularly noticeable and will be much more
pleasing to the eye.
Lowest Corner
14 Heritage Vinyl Cladding Installation Guide
Patios, Entrances or other Variations of Level.
At these obstacles starter strip is not appropriate as the portion of the board which engages the
starter strip will be cut off. In these cases a ‘J’ channel should be used. The ‘j’ will require a packing
piece in the back of it or an undersill, which ever is appropriate to maintain its original profile.
Outside Corner Posts
Measure from the top point on the corner of the house (i.e.: to the eave level) down to the
bottom of where the first board will be. This is the length of the corner post. Begin by nailing at
the top of the slot, halfway up the post. The rest of the nailing must be in the centre of the slots.
If more than one length is required, refer to the section on materials for cutting and overlapping
instructions.
NOTE: If you are installing eave linings as well, these should be done first, so that the wall trims
can be fitted up against them.
It is important that the outside corner posts are installed accurately and squarely to the corner. It
is possible to pull the corner out of shape if care is not taken, resulting in unevenness.

Internal Corner Posts should be finished with two ‘J’ channels with caulking between them to
prevent water entry or alternatively one ‘J’ channel with an effective flashing behind.

‘J’s’ are to be used as trims around the perimeter of windows and doors, tops of walls and
perimeters of gables, meter boxes, verandahs etc.
“J’s” are to be cut in such a way that they are folded for internal bends so that they act like a
watercourse.

16 Heritage Vinyl Cladding Installation Guide
Basic Rule: All higher “J’s” overlap lower “J’s”.
When this trim is folded it will overlap the right hand side of itself forming a weather lip but most
importantly will conform to the system of overlapping all of the trims (i.e.: Top piece overlaps
bottom piece). Similarly for steps;
“J” channeling should always be started at the lowest point and work up.
This end is ready to receive trims to be cut.
This end is ready to fit into already installed lower “ J “.
***NOTE: Wooden windows must have
their sill horns cut flush with outside edge
of side architraves.
“J’s” for doors, windows, air conditioners,
etc., should be cut like this:
As you can see these trims will all
interlock serving two purposes:
1. To make neat mitred joins
2. To help keep water away from the
window frame
17Heritage Vinyl Cladding Installation Guide
Undersill or Finishing Trim
Undersill (U/S) is installed inside a “J” Channel only. It can be used anywhere there is a
longitudinal cut on the wall boards (i.e.: over and under doors, windows, meter boxes,
verandas, etc). One of its uses is to hold the siding rigid where it has had to be cut off. BUT
most importantly, it is used as a fastening system for the top board of a wall or under a door or
window. The U/S trim should be positioned so as to maintain the natural profile of the siding.
Layout of Boards - Siding Panels
On the front and back walls, overlaps are to face away from entering pedestrians, to make them
less noticeable. On the sidewalls, the overlaps should be facing the rear. In some instances,
joins can be concealed behind gateposts, down pipes, sewer vent pipes, pergolas and all the
like. However, where there is no camouflage, overlaps should be either stepped up the wall
starting the first step to the rear, or if it is the customer’s preference a brick work pattern may be
appropriate.
Crimp
U/S trim can also be used over windows
and verandas in the same way.
18 Heritage Vinyl Cladding Installation Guide
Always check overlapped ends for neatness before application. The overlap cut should be cut out at
the top of the overlapping boards; the under lap cut out at the bottom of the under lapped board.
Overlaps must never be stacked upon each other as they rely on the board above and the board
below to lock them into position.
If joins must be stacked, they have to terminate in a “J” Channel and begin again from another
(i.e.: back to back “J’s”).
Wall board overlapping should be 35-40mm in a 50mm cut out.
General Tips
No board should be cut less than 1000mm where it is used to make up the full length of a wall
longer than the full board length (i.e.: If a wall is 8.5m long, don’t use 8m+ .5m, use 7.5m+ 1000
or 7m+ 1500mm etc).
The first panel is engaged into the starter strip and the corners or J channels and nailed in the
centre of the board. Nail both ways at 450mm centers (i.e.: stud spacings).
Ensure that the siding is not nailed so tightly to the wall as to prevent its natural expansion. Also
that the 5mm has been observed at the ends of the board for the same reason. (See section
“Allowance for expansion and contraction”).
EXPANSION ALLOWANCE
Remember: Always allow for expansion.
REMINDER: DO NOT NAIL AT THE ENDS OF THE SLOTS.

Armour Board Installation
When fitting Armour Board joiners, the joiner should be
inserted against the end of the fitted board, and the correct
allowance made for expansion and contraction when
cutting the next board. Do not fit the board with too much
clearance, otherwise the joiner may fall out.ALLOWANCE FOR EXPANSION

Windows and Doors – (Chamfer & I10 Board)
To fit the boards around openings, such as windows, doors, meter boxes and the like, measure
from the bottom of the locking strip. At the last full panel of siding, measure and cut the board
to allow the crimped panels top edge to engage the under 'J' trim with 5mm clearance.
Alternative method for checking cut out width of board is to use a scrap piece and then taking
the measurement from the marked piece.
Use the snap lock punch (crimper) to perforate the trimmed edge of the siding panel at 200mm
intervals. Ensure the punched ears are facing forward so they will engage in the under-sill trim.
Lock the top edge of the trimmed board into the under-sill trim ensuring at the same time that it
is engaging the locking lip of the board below.
The snap lock punch (crimper) must be used on all upward locking chamfor and I10 boards when
a trimmed panel is engaged in an under-sill trim.
To fit siding over the top of a window or door, etc. cut the bottom section of the panel (leaving
clearance for expansion/contraction) so that the trimmed edge engages fully in the under-sill or “J”.
Allow 5mm expansions on both sides of

Installing Armour Board around Windows & Doors
Under-sill may be required for Armour Board. Fit as for I10 above. No under-sill trim is required for
Armour board, because of its backing and its fastening system, also the measurements are taken differently.
When cut to size this panel will sit as the above to complete its installation. An upward push hit with your hand, on the bottom edge of the board starting at one end and traveling along as it
snaps in, is the preferred method.
NOTE: The top edge of the board must first be placed in position.
Certain instances, where the top board finishes at its thinnest point, the back face of the J30
must be packed to ensure that the top board will not be loose when installed.
Note: A 2 part J may be used at the top of walls.

Top of Wall Finish
Siding is measured and finished off at the top of the wall in exactly the same fashion as under a
window or door for each of the insulated or non-insulated types.
In some unavoidable instances you will observe a bow or a sag in the eave line that cannot be
practically remedied. To cut the board accurately, you should mark the wall at 1000mm intervals
and measure the height at each interval.
0 = 150 1 = 140 2 = 130 3 = 130 4 = 140 5= 160 END = 165
Finishing Gables
Trim the gables around the perimeter and cut the boards on the correct angle allowing expansion
and fasten as per wall cladding. In instances where fastening is limited, the gable may need to be
battened.
Board height should be checked first to find the point of intersection with the ‘J’ channel, These
points are then marked as a measure along the top edge of the already installed board. This
will show the height at start or 0 mm, length as 0mm. The point of intersection (i.e.: boards full
heights) as 670mm. The point it meets the ‘J’ again as 1350 mm and the point it finishes at 0mm
high as 2020mm. Check the expansion space on every board before fixing.

Installing Soffits
To be fastened at 450mm intervals.
For eave applications on houses with enclosed overhangs, start by installing the J channel at
either side then cutting board with an allowance for expansion.
For application on buildings with open rafter construction, the wall must have a batten installed
for the j channel fastening and the eave lining fastening. An intermediate nailing batten will be
needed if the overhang exceeds 450mm.
For eave installations with a new fascia cover, the outside J can be deleted. However, the inside
eave J should be installed as a water proofing agent. The top wall J should be sealed against the
inside eave J.
To mitre eave linings, install back to back “J” channels and cut out eave linings to suit.

WAVERING EAVES: Quite often eaves can waver up and down; these can be straightened out
usually by installing eave J15 on a straight line rather than following the existing waver.
CUTTING: Extreme caution should be exercised when cutting siding with power tools, because
of its light weight. Cutting should be done with the blade installed back to front; otherwise the
siding may throw off dangerous fragments.
Use plywood cutting blade or similar.
Extreme caution must be exercised to stop the blade from “running on” on the board.
*******ALWAYS WEAR EYE PROTECTION******
LIGHTS AND DOORBELLS: When fitting lights and
other fixtures over cladding it is sometimes necessary
to pack behind the cladding to prevent crushing of the
profile. Also slot holes laterally and do not over-tighten
fittings as to prevent expansion and contraction.
TRIMS: The recess in an OCP and a ‘J’ channel are the
same width. This creates a difficulty with intersecting
them. The most appropriate way is not to fasten the
top and the bottom 450mm of the OCP until the ‘J’ is
inserted with both flanges of the ‘J’ behind the flanges
of the OCP. When the ‘J’ is positioned accurately the
corner may then be manipulated to sit correctly and
not flare at top or bottom.

REGULAR MAINTENANCE:
With very little maintenance, VPI Vinyl Siding can be kept looking clean and new. We recommend that you wash your house 3 times a year to keep the Vinyl Siding’s appearance.
Use a long handled soft bristle brush that attaches to your garden hose, start at the top of your house and work down to the bottom to prevent streaking.
If any dirt, grime or soot is present and hard to remove, wipe down the Vinyl Siding with a solution of mild dishwashing detergent and warm water.
A mild liquid car wax may be applied to the water. This will assist in retaining the “new” look of your Vinyl Siding for many years
DO NOT use any harsh detergent, or products containing bleach or insecticide.

26 Heritage Vinyl Cladding Installation Guide
Examples of Expansion Calculations:
We are fitting a board to a section of wall that is 5.00 meters length inside the trim.
1. The temperature is 20°C: The calculation for 20°C is 1 millimeter per lineal meter of board
length plus 10 millimeters. The calculation is:
1 millimeter x 5 metres + 10 millimeters = 15 millimeters.
Therefore, we cut the board at 4.985 meters. Fit the board so that there is an equal gap
between the trim and the board at each end.
2. If the temperature was 10°C, then the calculation is:
1.5 millimeters x 5 metres + 10 millimeters = 17.5 millimeters.
Therefore, we cut the board at 4.983 meters. Fit the board so that there is an equal gap
between the trim and the board at each end.
3. If the temperature was 30°C, then the calculation is:
0.5 millimeters x 5 metres + 10 millimeters = 12.5 millimeters.
Therefore, we cut the board at 4.988 meters. Fit the board so that there is an equal gap
between the trim and the board at each end.
4. If the temperature was 40°C, then the calculation is:
10mm extra allowance
Therefore, we cut the board at 4.990 meters. Fit the board so that there is an equal gap
between the trim and the board at each end.
