What are the Supercrete™ Panel Cladding Systems?The Supercrete™ Panel Cladding Systems comes in a 50 and 75mm thick option. This is a platinum choice of cladding for discerning builders, housing companies, designers and home owners nationwide. Based on the hugely successful 75mm thick Supercrete™ Panel Cladding System, now we can offer the more economic Supercrete™ 50mm option which still provides that same great look, but now at an even more attractive price. The Supercrete™ Panel Cladding Systems are cost competitive with most other common claddings, such as rendered brick, polystyrene EIFS, fibre cement sheet and stucco plaster, yet it has the added benefits of being thermally and acoustically insulating, fire resistant, non-toxic, breathable, durable, lightweight, straight and accurate. These panels are cut with basic power saws with diamond tip blades and the screw fixings are easily driven with an electric drill.One Supercrete™ Panel covers the same area as 65 bricks in a matter of a few minutes. Installed by Registered Supercrete™ Panel Installers and Registered Supercoat™ Coating Applicators, the Supercrete™ Cladding Systems makes finishing your next house a breeze. The Supercrete™ Panel Cladding Systems are available your from local Supercrete™ Distributor who are Superbuild International Ltd’s authorised suppliers of this cladding system. Their Registered installers and coating applicators perform the work to apply the cladding. Supercrete™ Distributor contact details for each region of New Zealand are available on the website, www.superbuild.co.nz.

Thermally InsulatingBuildings must be insulated to create a stable, comfortable internal environment. In winter, heat should be prevented from escaping to the outside and in summer, the interior

should be protected from the heat of the sun. Having good insulation reduces the energy costs for mechanically heating and cooling a building.Efficient insulation must be at a level where the lifetime cost of resulting energy savings is of more benefit than the cost of increasing the insulation. Insulating materials must also practi-cally fit within a manageable wall thickness.

Acoustic InsulationPreventing external noise from entering a building is im-portant for creating a comfortable internal environment. Airborne sound waves are blocked by building walls using a combination of reflecting, or bouncing the sound off hard surfaces and absorption, or muffling of the sound waves, by diffusing and breaking the wave pattern as it passes through the air spaces of the wall insulation.

Fire ResistantAs a non-combustible material, Supercrete™ panels will not burn. The entrained airspaces in Supercrete™ panels, combined with the batten space between panel and frame, insulate the structure of the building. Frames are protected from heat damage where the fire source is located at the panelled face of the wall.

DurableSupercrete™ does not decay over time. Whilst surface treat-ments may need touching up as the decades roll by, building owners can be confident that the Supercrete™ substrate will still be as good as new… generation after generation.The Supercrete™ Cladding Systems have been appraised as meeting the building code minimum durability requirements.


Easily WorkedPanels are lightweight and even the largest panels can be handled by two people.Unlike other masonry products, Supercrete™ is easily shaped and worked with a variety of standard carpentry tools. Supercrete™ Registered Panels Installers cut the panels with a standard 210mm circular saw, fitted with a segmented diamond tipped blade, or Turboblade. Small cuts and chases are easily formed with wood chisels or hand saws. Holes are simply drilled with masonry bits. No pre-drilling is necessary for panel screw fixings. Coarse sandpaper quickly smooths any surface imperfections.

AccurateThe crystalline structure of Supercrete™ AAC makes it very dimensionally stable. All panels are factory cut to exacting standards. If framing is misaligned or bent before cladding, battens are normally packed by the Registered Supercrete™ Panel In-staller with DPC or similar to correct this, ensuring a straight panel surface.

Stylish Good Looks and Great PerformanceThe Supercrete™ Cladding Systems provide clean smooth lines and a high quality finish. The 50 and 75mm thickness of the panels gives a solid look, particularly noticeable around openings, where the depth of window setback shows off the truly substantial solidity of a Supercrete™ Panel Clad building.

Versatile• In addition to cladding framed buildings, Supercrete™

Cladding Systems can also used for fencing, interior partitions, decorative accent features on building facades, fireplaces, gas cylinder enclosures and letterboxes.

• The Supercrete™ Cladding Systems are ideal for retrofitting to older houses to replace existing claddings. It can improve the appearance, and the thermal and acoustic performance of existing buildings.

• Supercrete™ Cladding Systems can be used successfully on multi-storey structures providing allowance is made for movement joints at each floor level.

Installation ProcessOn a new building, the framework is first wrapped in building paper to provide temporary weatherproofing to the frame. Horizontal steel Tophat battens are then screwed to the vertical framing members. The number of battens depends on the buildings’ exposure to the wind but would normally be either 3 or 4 battens per storey. Very narrow vertical panels will require some battens to be placed vertically for

full support, and sloping gables also require sloping battens. The majority of panels are fitted in a vertical orientation.Panels are cut to size using a segmented diamond blade in a portable power saw and are cut dry. Curved shapes can be cut with reciprocating saws fitted with diamond or tungsten grit blades.Each panel is screwed into place using screws driven through from the front of the panel into the battens where they self tap. Panels usually sit in a rebate in the floor slab on Damp Proof Course (DPC) but the weight of the panels is fully supported on the screws. Therefore, on panels above deck areas or above roof lines, it is not necessary to provide any extra support at the base of the panels.At most corners and at nominal 4 metre spacing along walls, movement control joints are used to allow the panels to take up any building movement transferred through from the framing. These joints are fully sealed, and when done correctly, should be unnoticeable after the final coating. All other panel joints are edge glued using Supercoat™ AAC Superbond Adhesive which has a higher strength than the Supercrete™ AAC panels.Windows and doors are fitted before panel installation. Panels are fitted between these, and then above and below openings. Note that windows should have face drained extrusions. All screw holes are filled, and any raised edges or glue lines are sanded back with a sanding float to provide a smooth uniform surface ready for the coating or plaster system of choice.All battens, fastening and tools required for the installation of the panels are supplied by your local Supercrete™ Distributor.

Architectural DetailsWindow sillsPanels below windows are site cut to a 30 degree slope. Sill blocks are available to provide a drip edge at the base of windows. These are 50mm thick with a 30 degree top slope to align with the panel at the base of the window. These blocks are simply fixed with Supercoat™ AAC Superbond Adhesive and temporarily held in place with nails. The Supercrete™ AAC is soft enough to drive nails into without pre-drilling. Larger sills can be cut from any desired Supercrete™ Block thickness.

Mid-floor bandsWith multi-storey buildings, vertical timber shrinkage will reduce the overall height of walls. To accommodate this movement at each floor level, a mid-floor band block can be used to cover the joint. These are glued only to the upper panel at the joint to allow the upper panels to move independently, along with the mid-floor band, from the lower panel.


Banding around openingsTo provide accents around window and door openings, Supercrete™ Block can be glued to the face of the panel. The minimum recommended size is 100 x 50mm, cut from 250 x 50mm blocks. Thinner bands are susceptible to breakage when handling.

Column and Beam accentsExtra panels can be glued on the face of the cladding to provide raised column, beam and base relief panels depending on the architectural style. The fastenings for the cladding panels should be checked in these cases to ensure that they can support the additional weight.

Parapetsa) Cantilevered Panel Parapets

Low parapets can be formed by extending the wall panels above the roof line, with another panel following the roof line glued to the rear of these, to give a 150mm thick cantilevered parapet. A parapet capping can be formed using 250 x 50mm blocks.

b) Fully Framed Parapets

The parapet can be fully framed and panel fixed to both sides. With 100mm nominal framing, this will give a parapet thickness of 300mm and a parapet cap can be formed by simply gluing a 300mm wide panel on the top. On all parapets, the top surface should have a roofing type membrane or flashing for waterproofing.

Columns and beamsColumns for verandahs etc. can be clad in panel. A minimum size of 250mm square is recommended. Beams can also be encased in panel if a matching finish with the house is desired, but a minimum width of 250mm is usually required.

ArchesArches over windows are simply formed by cutting the panel to shape. Where these are required between columns, the curved underside of the arch can be formed by gluing 250 x 50mm blocks transversely to the underside of the panel on either side.

Mouldings, Corbels etc.Where ornate architectural features are desired, these can be easily formed from Supercrete™ Block using any power or hand woodworking tools. These blocks are unreinforced and can therefore be shaped as desired without interference from reinforcing.Any shaping or grooving of the panel face can only be a maximum of 5mm deep, otherwise the reinforcing cover is compromised.


BalconiesPanel can be used to clad solid balustrades if these are suitably framed. However, as with all balustrades, consideration must be given to the lateral support of the structure. If panel is required on both sides, the overall thickness will be 250mm and the top can be capped with a 250mm wide panel. However if a thinner balustrade is desired, with Supercrete™ 50 or 75mm Cladding Systems only on the outside, for a homogenous base for the coating system, the interior face can be clad in any approved external use sheet material.

AttachmentsAs with all cladding systems, any external attachments to a building, such as pergolas, handrails or clotheslines, should not be fastened to the cladding. These should be fixed to the wall framing behind and will require some pre-planning as to location. All bracket penetrations through the panel should have a sealed movement joint around them.For lightweight attachments, such as light fittings or signage, expansion anchors are available especially for use with AAC.

Panel LayoutYour local Supercrete™ Distributor will provide a panel layout for each wall to show how best to arrange the panels. This is used as the basis for overall quantities and pricing.
