Clip Strip Options:

• Flat clip strip: Depth of 23.5 mm, capable of spanning with a minimum 23.5 mm ventilation gap.
• Channel clip strip: Depth of 25.4 mm, capable of spanning with a minimum 25.4 mm ventilation gap. Direct attachment to the wall is possible.
• Top hat clip strip: Flexible and depth adjustable, requires continuous support. Ventilation gap size can be adjusted.

Board Sizes:

• Board Size 3: Requires a coverage of 76.3 mm.
• Board Size 6: Requires a coverage of 152.6 mm.

Product Usage Instructions

Step 1: Determine Wall Deviations

Before starting the installation, check if the wall has any deviations in all three planes (x-axis, y-axis, z-axis). Ensure that the wall is structurally suitable and assess existing conditions.

Step 2: Choose Clip Strip

Select an appropriate clip strip based on the existing wall conditions:

• For flat walls with a minimum ventilation gap of 23.5 mm, use the flat clip strip.
• For walls that allow direct attachment and require a minimum ventilation gap of 25.4 mm,use the channel clip strip.
• For flexible depth adjustment and continuous support, use the top hat clip strip.

Step 3: Choose Board and Material Technology
Select a board and material technology suitable for your project.

Step 4: Determine Number of Boards

To calculate the number of boards required:

1. Determine the board quantity (BQ) using the formula:BQ = (Wall height – Flashing and trim gap – Ground clearance) / Board coverage
2. If the quantity of boards is not a whole number, an offcut will be required. Calculate the offcut using the formula: Offcut = (BQ – Whole boards) * Board coverage
3. If the offcut is greater than 70 mm, the last board can be ripped. Adjust ripping size accordingly.

Step 5: Plan Board Layout

If offcuts are less than 70 mm, the first board can also be ripped. Alternatively, adjust the trim position or allow for a larger gap.

TYPICAL VISTACLAD INSTALLATION PROCESS

Thank you for choosing VistaClad cladding products. This quick start guide aims to provide the essential information required to install the VistaClad system.

VISTACLAD QUICK START GUIDE

STEP 1
Determine if the wall has any deviations
Before proceeding with construction, it is essential to confirm that the wall is structurally suitable, assess existing conditions,and determine any deviations in all three planes.

STEP 2
Choose an appropriate clip strip for the application
The VistaClad system provides three clip strip options. The existing wall conditions may influence the choice in strip.

STEP 3
Choose a board and material technology

When selecting a material technology for the cladding system, it is crucial to consider how the material technology type,colour, and profile length will affect the final board length after installation. Board length is affected by temperatures on-site and will grow (expand) or shrink (contract) inrelation to site temperatures. Trim can be used to conceal the change in length, resulting from these temperature changes. It is important to provide enough space to accommodate board expansion and ensure that the board will not contract past the trim. If expansion gap sizes are a concern, choose lighter coloured profiles and materials technologies with lower expansion coefficients. Alternatively consider shortening board length and using more butt joints within your planned board layout (See step 5). If the backside of the boards is exposed to UV rays, use a backing board or
film. For guidance on how to calculate and account for expansion and contraction, consult the full installation guide.

STEP 4
Determine the number of boards

To establish the number of boards required for the cladding system, remove any additional clearances and trim edges from the full height of the wall before dividing this by the board coverage. Two typical board sizes are available 3“ (requiring 76.3 mm coverage) and 6” (requiring 152.6 mm coverage).

1. Calculate the board quantity (BQ) = Wall height – Flashing and trim gap – Ground clearance Board coverage (Typically 76.3 or 152.6)
   Example

   • BQ = (3000 Height – 60 – 70 – 50 )/152.6
   • BQ = 2820 / 152.6
   • BQ = 18.47 Boards over the height.

2. Where the quantity of boards is not a whole number, an offcut will be required.
   Offcut = (BQ – Whole boards) * Board coverage.
   Example

   • Offcut = (18.47 – 18) * 152.6
   • Offcut = 0.47 *152.6
   • Offcut = 71.72 mm.

3. Adjusting ripping size
   If the offcut is greater than the minimum requirement of 70 mm, the last board can be ripped.
   Anything less than half of a full board will require additional adjustment as illustrated below.

STEP 5
Planning board layout

Once the wall has been assessed, the appropriate clip chosen and the number of boards calculated along the height of the wall, the horizontal laying pattern can be addressed.

VISTACLAD CLIP INSTALLATION PROCESS

STEP 2a Horizontal installation

1. Install furring. Ensuring that the furring is plumb, level in all three planes and at the spans needed to support the clip strips.

2. Run a builders line between the two outermost points, 75 mm (Remember to account for any additional space for flashing) from the top line of the cladding installation

3. Fasten small screws with heads smaller than 8mm along the builders line at every furring strip.

4. Hang each clip after cutting the clip strip to length from the screw from the largest top most hole. As indicated in the image.
   Note: Treat any exposed or cut steel edges before installation.

5. Lock” the first clip strip into place by fastening the strip in at least three locations at the required spans. This clip strip will become the reference point for all other clips strips.
   Note: Once all clip strips have been fastened into place and are level, return to fasten the clips at the appropriate spans required for installation.
   Tip: Use a torpedo level to check that the clip strip is plumb. The furring or intermediate structural parts should provide a level surface for the clip strip.

6. Level the clip strips (as illustrated) in all 3 planes.
   The clip strips ledge provides the most convenient and accurate point of reference.
   Tip: Use a straight edge and level at least three times the span, to level the clip strips.

Note: Once all clip strips have been fastened into place and are level, return to fasten the clips at the appropriate spans required for the installation.

STEP 2b Vertical installation

1. Install furring. Ensuring that the furring is plumb, level in all three planes and at the spans needed to support the clip strips. Provide gaps for ventilation and drainage.
   Note: Do not use flat strips for vertical applications. Top hat clip strips are best suited to the application and require no additional furring.

2. Vertically laid boards require additional support as they will slide down.
   Install a structural element with drainage holes (Perforated angle). Allow for 1 500 to 2 500 mm²/m perforations with holes no larger than 9.5 mm.
   Structural elements can be 2.0 mm thick for steel and 2.5mm thick for aluminium. Width and height would depend on the clip and board combination.
   Thickness is based on the assumptions that the structural element will be supporting a board load of 16 kg/m². (board length is a maximum of 5.8m)

3. Fasten each horizontal strip at the top two most extreme edges ensuring that they are level.

4. As per step 6 of the horizontal installation, use levels or plumb lines to ensure that the ledges are aligned.
   Install additional perforated angles where vertical boards may require support, such as window lintels and butt joints.
   Note: Once all clip strips have been locked into place and are level, return to fasten the clips at the appropriate spans required for the installation

STEP 2c Channel and top hat clip strips

Both channel clip strips and top hat clip strips are rigid members that are capable of spanning. Additional fastening points have been provided along the side faces of the channels and top hats to allow for wall deviations as indicated on page 1. The size of these members allow for fastening or clipping over 1.5 “ or 38 mm structural members and composite battens. When fastening from the side ensure that the edge distances within the structure are adequate.

VISTACLAD TRIM ADAPTOR INSTALLATION

VistaClad has a trim adaptor and aluminium trim available for a quick and neat installation. Adaptors fastened to the clip strip remove the need for fastening through composite profiles. Trim adaptors must be installed before boards.

1. Top and bottom adaptor
2. Side adaptor
3. Internal corner adaptor
4. External corner adaptor

Note:
Ensure that there is support behind the clip strip when fastening adaptors.
VistaClad trim and adaptors are used to cover board edges and additional flashing may need to be installed at this phase.
See the flashing section on page 12 before continuing.

VISTACLAD BOARD INSTALLATION

STEP 4a Horizontal installation

Align the first board with the clip
Fully supporting the full length of the board. Place the board above the clip. Aligning the feet with the clip hooks.

Note: At lengths of larger than 4 spans, two people should install the board

Press down
Start at one side of the board and push or lightly knock the top of the board with a soft mallet into the boards final position.

Ensure that the board is fully clipped in along its full length before starting the next board

Align the next board and press down

Align the board against the tongue of the previously installed board and placing the board against the clip. Press down from one side of the board to the other.

STEP 4b Vertical installation

Align the first board with the clip
In vertical applications boards over 3 m may be prone to buckling before insertion. A minimum of two installers are recommended. Ensure that the top of the board is fully supported before attempting to insert the board.

Press down
Start from the top of the board, push or lightly knock the top of the board with a soft mallet into the boards final position.

In vertical applications, provide enough clearance in internal corners to insert the next set of boards.This can be achieved by inserting boards from a single direction.

Installation around windows and other obstacles

1. Install additional clip strips, 70 mm from the edge of the window as per standard edge distances.
2. Install side adaptors and top and bottom adaptors at window corners and as per recommended spans of 450 mm.
3. Install boards as per standard methods. Where nessasary rip boards and leave a 10 mm gap to allow clearance below the window sill.
4. Install and join universal trim around windows before sealing along all edges. Ensure adequate water tightness.

FLASHING INSTALLATION AND OTHER DETAILS

The VistaClad trim system is designed to cover board edges while removing the need to fasten through the composite boards. Additional
flashing is required to cover wall cavities and prevent water ingress. Combinations of trim and furring can be sealed with adhesives and flashing tape. Flashing needs to be installed at strategic points in the installation as detailed below.

Flashing depth = Furring width (Including clip strip) + Board thickness

1. Before installing the cladding boards and adaptors, install flashing directly to the wall. Flashing at the bottom of the system should be perforated to allow water to escape, regardless of installation type.
   Use cover flashing around edges.
   Use perforated angles at the bottom of the system to allow water to escape.

2. Install boards and trim as per previous steps.

3. Install Z-flashing so that it overlaps the universal trim.

4. Seal all edges using flashing tape, sealant and if nessasary overlapping flashing to direct the flow of the water,dependant on regional and design requirements.

Working around small penetrations
Allow for 5 to 10 mm of clip hook clearance in vertical movement for board insertion.

Working around large penetrations
Provide additional clip strips on either side of the part to support the board ends. Allow for 5 to 10 mm of clip hook clearance in vertical movement for board insertion.
