Fix the QT EcoSeries Wall Panel onto timber battens or metal channels with galvanised
75mm x 3.15 or 3.75mm ring shank nails (timber battens only) or 10g x 75mm Class 3 (AS3566) screws (timber or steel battens) with the addition of QT Buttons in all cases. Panel fixings must be no closer than 50mm but no further than 112mm to the horizontal panel edge and no closer than 50mm to the vertical edge, while normal fixing centres are at 225mm maximum centres. It is essential that the vertical and horizontal butt joints be bonded with polyurethane foam adhesive. Also ensure polyurethane foam adhesive is applied to all batten faces prior to the panel being pushed against them for maximum bonding to the support frame. Panels can be joined off stud, if glued to the abutting panel with polyurethane foam adhesive. QT EcoSeries Wall Panels can span 225mm as an unsupported cantilever. Panels must span across a minimum of two channels or battens and must be installed in a horizontal stretcher bond pattern. To prevent corrosion from salt aerosols in high corrosion zones, (such as geothermal activity or within a 500m distance from the sea) upgrade fixing screws to class 4 or stainless steel (AS3566).

2. 2 Framing

Timber framing must comply with AS 1684 and steel framing must be designed and constructed in accordance with AS 3623. Minimum distances from end and edge of timber framing members must be observed to avoid splitting. Stud spacing must not exceed 600mm centres. Noggings must be fitted between studs at 1350mm maximum centres.

With a 1.8 m spirit level, check for variations in the frame that are over 6 mm. Large variations negatively affect weather protection or can appear as visual defects under critical light conditions. If the frame is out of plumb, but not structurally defective, consult with the builder or contractor for remediation.

Silhouette opens a whole new world of possibilities for creating a building’s personality. SilhouetteT allows architects, developers and builders to select from a range of feature details or even to create their own custom design for external claddings.

Attractive and competitively priced, Silhouette offers a fresh approach to cladding options.

Silhouette comprises of a fibre cement plank and a uPVC feature strip. Together these components clip together to obscure fixing points and to form a seamless cladding appearance of your choice.

The Silhouette exterior cladding system:

• choice of 3 individual profiles – urban, coastal and classic
• custom design profiles
• unique and stylish
• simple and quick to install – just clip in profile
• economical – no waste in laps
• lightweight material

*some sizes may not be available in all states, please check with your local BGC office for availability.

Unloading Bundles

Panels shall be unloaded and moved with only approved lifting devices. Before use, the lifting device should be checked for the required lifting tags. Panels should be unloaded as close as possible to the intended installation area. This will increase work efficiency and minimise the need for secondary lifting.

Note: Secondary handling increases the risk of panel damage. The repair of damage sustained during lifting and moving is the responsibility of the lifter. Where damage is excessive, panels must be replaced.

Storage

All materials must be kept dry and preferably stored under cover. Care should be taken to avoid sagging or damage to ends, edges and surfaces.

All Hebel products must be stacked on edge and properly supported off the ground, on a level platform. Panel bundles can be stacked two high. The project engineer should be consulted as to the adequacy of the structure to support the stacked bundles. Each bundle contains 10 Hebel PowerFloor panels. Where bundles are stacked two high, the supporting cleats must be vertically aligned, to ensure minimal bending of the lower panels. Refer to Fig 3.

If Hebel PowerFloor panels are stored outside, they must be stored off the ground and protected from the weather

Only single bundles positioned on the ground can be opened. To provide a level surface, we recommend placing temporary joists beneath the supporting cleats.

Fig 4.1.1. Stacking Bundles of Hebel PowerFloor

*Unstraping Bundles

Ensure appropriate bracing is installed to bundles prior to removal of strapping to prevent panels from falling. Panels can be held together with sash clamps, ratchet straps or Hebel stabilising bars.

4.2 Panel Handling

Manual Handling

To minimise the possibility of manual handling injuries, CSR Hebel suggests the following:

• Use mechanical aids, such as trolleys, fork lifts, cranes and levers, or team lifting to move panels.
• Keep the work place clean to reduce the risk of slips, trips and falls which can cause injury.
• Plan the sequence of installation to minimise panel movements and avoid awkward lifts.
• Keep the panels dry.
• Train employees in good lifting techniques to minimise the risk of injury.

Hebel products are cement-based, which may irritate the skin, resulting in itching and occasionally a red rash. The wearing of gloves and suitable clothing to reduce abrasion and irritation of the skin is recommended when handling Hebel products.

4.3 Tools and Equipment

The basic tools required to assist in the installation of the Hebel PowerFloor are shown in Figure 4.1. These may be purchased through CSR Hebel and include:

1. Mixing bucket
2. Stirrer
3. Trowel
4. Sanding float
5. Panel lifters
6. Levelling plane

Extra equipment will also be required and includes the following:

• Power drill (clutch driven)
• Power saw with metal or diamond tipped cutting blades
• Dust extraction system
• Sockets and bits for screws
• Personal Protective Equipment (PPE) such as goggles, face mask and P1/P2 dust masks, used when site cutting the panels

Installation Procedures

CSR Hebel promotes and advocates a safety conscious work place at all times. To assist builders and contractors to maintain their safety standards, CSR Hebel has produced guidelines for the installation and handling of their products. Contact CSR Hebel for additional information.

Mortars & Adhesives

The Hebel bagged mortar and adhesive should be prepared in accordance with instructions on the packaging.

Damaged Panels

Chipped or damaged panels are to be repaired using Hebel Patching Mortar. Your Hebel supplier should be notified immediately of any panel damage or cracking that occurs during the handling of the panels. This damage may result in the panel being structurally inadequate, in which case it must be replaced.

Panel Cutting

Hebel PowerFloor Panels to be cut with a circular saw fitted with a diamond tipped blade. The use of power tools may cause dust, which contains respirable crystalline silica, with the potential to cause bronchitis, silicosis and lung cancer after repeated and prolonged exposure. When using power or hand tools on Hebel products, wear a P1 or P2 respirator and eye protection. When cutting, routing or chasing Hebel products with power tools, use dust extraction equipment and wear hearing protection. Refer to CSR Hebel MSDS sheets.

Reinforcement exposed during cutting is to be coated with a liberal application of Fentak.

4.5 Hebel PowerFloor Installation Sequence

1. Preparation of Framing for Hebel PowerFloor Panel Installation

• Check floor framing is complete and within level tolerances.
• Provide set-out chalk lines, as required.
• Provide temporary installation platform where necessary.
• Ensure floor framing has adequate strength to support Hebel PowerFloor bundles.
• Position Hebel PowerFloor bundles on the floor framing.

2. Hebel PowerFloor Panel Installation

• Panels are to be installed in a stretcher bond pattern, with a minimum overlap of 1 joist space and not less than 450mm.
• Use lifting handles or trolley to move the panels to installation area.
• Apply a 5mm min. bead of Fuller Max Bond construction adhesive (or equivalent) to top of joists in accordance with manufacturer’s instructions, and apply Hebel Adhesive to appropriate panel edges.
• Panels must be installed with minimal horizontal sliding on the joists to ensure a good bond. Force the tongue and groove joint closed as the panel is rolled and lowered onto the joists. Ensure all joints are tight and that adhesive makes full contact along all joints.
• Screw fix panel to the joists as required.
• Repeat process, removing excess Hebel Adhesive.

3. Penetration Detailing

• Install blocking to support Hebel PowerFloor panel at major openings.

4. Floor Finishes

• Sweep the floor surface to remove debris and loose particles.
• Fill joints and screw holes with Hebel Adhesive, as required.
• Ensure perimeter is not chipped.
• Install floor covering for Hebel PowerFloor system in accordance with manufacturer’s specifications.

Note: Ensure panel moisture content is within limits outlined by the floor covering manufacturer.
