Install LYSAGHT MULTICLAD® cladding

This page contains details on installing LYSAGHT MULTICLAD® cladding. For more information see Install LYSAGHT® Steel Roofing & Walling.

Please be aware that installation of cladding must be carried out by a licensed tradeperson in some Australian states.

Fasteners

Where insulation is to be installed, you may need to increase the length of the screws given below, depending on the density and thickness of the insulation. When the screw is properly tightened:

• into metal: there should be at least three threads protruding past the support you are fixing to, but the Shankguard must not reach that support;
• into timber: the screw must penetrate the timber by the same amount that the recommended screw would do if there were no insulation.

Metal and Timber Compatibility

Lead, copper, free carbon, bare steel and green or some chemically treated timber are not compatible with this product. Do not allow any contact of the product with those materials, nor discharge of rainwater from them onto the product. Supporting members should be coated to avoid problems with underside condensation. If there are any doubts about the compatibility of other products being used, Contact Us.

Maintenance

Optimum product life will be achieved if all external walls are washed regularly. Areas not cleaned by natural rainfall (such as the tops of walls sheltered by eaves) should be washed down every six months.

Safety, Storage and Handling

Handling Safety - LYSAGHT® product may be sharp and heavy.

It is recommended that heavy-duty cut resistant gloves and appropriate manual handling techniques or a lifting plan be used when handling material.

Keep the product dry and clear of the ground. If stacked or bundled product becomes wet for extended periods, separate it, wipe it with a clean cloth to dry thoroughly.

Handle materials carefully to avoid damage: don't drag materials over rough surfaces or each other; don't drag tools over material; protect from swarf.

Cutting

For cutting thin metal on site, we recommend a circular saw with a metal-cutting blade because it produces fewer damaging hot metal particles and leaves less resultant burr than does a carborundum disc.

Cut materials over the ground and not over other materials.

Sweep all metallic swarf and other debris from roof areas and gutters at the end of each day and at the completion of the installation. Failure to do so can lead to surface staining where the metal particles rust.

Sealed Joints

For sealed joints, use screws or rivets and neutral-cure silicone sealant, branded as suitable for use with galvanised or ZINCALUME® steel.
