General Description & Compliance


3 LIMITATIONS & CONSIDERATION

3.1 LIMITATIONS

Plastercrete AAC facade system is applied to residential housing and light commercial buildings complying with NZS 3604 or NASH 3405. If specifiers require additional or modified details please contact Superbuild International Ltd or email [email protected].

3.2 CONSIDERATIONS

Plastercrete AAC panels must be installed by registered installers as per the details shown in this manual to ensure the quality of the facade system. They must not be installed in any situation where they will come into contact with the ground, and cannot be used as retaining walls.

Plastercrete AAC panels are Autoclaved Aerated Concrete. As with all concrete and fibre cement products, the dust produced when cutting or grinding them contains crystalline silica. This dust is irritating to the eyes, skin and respiratory system. Inhalation of this dust can cause irreversible damage to health. Wear suitable protective clothing and gloves at all times. When cutting, drilling or grinding panels do so in an open air environment or areas that are well ventilated and wear approved safety glasses and dust mask.

All aspects of cutting, drilling or grinding must comply with the latest regulations of the Occupational Safety and Health division of the labour department.

Plastercrete AAC panels should be stored on site on the pallets they were delivered on and kept covered & free of dampness until required. Care should be taken when handling to limit damage to edges or corners.

Any damage incurred to the coating or the AAC panels must be addressed immediately. The panel is not to be left exposed through damage to the coating.

The Supercoat™ plaster system must be maintained annually, to ensure the integrity of that system. (Refer to Supercoat™ Maintenance Guide)

3.3 CONSTRUCTION REQUIREMENTS

Steel framed walls or timber studs should be placed at not more than 600mm ctrs. Framing strength must comply with relevant NZ Standards for general framing construction suitability for the building.

Steel framed walls or timber framed walls are to be braced in accordance with wall facades shown in NZS 3604: 2011 and are to be based on the combined weight of the AAC panel and the coating system used.

The wall wrap complied with compliance document E2/AS1 table 23 must be fixed to the exterior wall framing prior to installation of Plastercrete AAC panels and battens. Ensure wrap is continuous around corners and installed horizontally.

Internal and external corners as per details following, if the distance between corners exceeds 10.0 meters, then control joints at a maximum of 10.0m centers are formed as per details. Responsibility for the locations of these controls joints is with the designer.

3.4 CONSTRUCTION GUIDANCE

3.4.1 Pre-installation check

Ensure the builder has completed items set out in the pre-cladding check list. (See section 7 for details)

3.4.2 Installation:

Cavity battens: the EPS 20 x 40 cavity battens (or 19 x 42 Cavibat battens) are attached to the building wrap using construction adhesive, for typical batten layout refer to the detail drawing No1. Cavibat battens come in two forms, one with vertical flutes for use in vertical stud applications, the other with horizontal flutes for use when attached to dwangs, the hollow flutes allow the passage of moisture.

Cutting: AAC panels are cut using a metal cutting blade. Zinc rich primer compliant with AS/NZS 2311:2000 is to be applied to all exposed reinforcing in the panels.

Fixing: AAC panels are fixed using 14-10 x 100 bugle head type 17 class 4 screws which are to be embedded 35mm min. into the timber frame, a minimum of 6 screws are required per AAC panel.

Laying: Once the cavity batten are fixed to the studs, fix the bottom row of Plastercrete AAC panels/ These panels are placed in a stretcher bond pattern as per the typical layout detail on drawing 2. Any imperfections on the face of the panels and the screws hole can be repaired and filled with the Supercoat™ Superbond panel adhesive, which is a rigid, high strength cement based adhesive.

Corners: At this point check the level and alignment of the panels. Corners should be placed with an overhang to line up flush with the connecting corner panel.

Flashings: Ensure all flashings have been placed correctly as per the details in this manual, cut the panels to suit the openings.

Plastering & coating: Ensure the panels are dry, clean and free of any dirt, dust or foreign matter before carrying out any plastering work, Supercoat™ plaster system is the only approved system for application over the Plastercrete AAC panel system. For more information, see the manufacturer’s specifications.


5 MAINTENANCE AND WARRANTY5.1 MAINTENANCE

The Supercoat™ plaster system should be regularly cleaned, at least annually, Chemical / detergent wash. Have the entire coated area inspected by a person with sufficient experience to identify any maintenance requirements to ensure weather tightness. Undertake all necessary repairs immediately.

Inspections of the complete cladding surface must be carried out at least annually at the end of summer. Because of settling after disturbances to the ground during construction, and the slow moisture-loss shrinkage of concrete slabs, it is recommended that six-monthly inspections be made for the first three years.

Any cracks or damaged areas, including flashings and seals that have deteriorated, must be repaired immediately to ensure the integrity of the building envelope is maintained.

Any damage to the substrate must be repaired in accordance with the substrate manufacturer’s instructions followed by re-plastering and recoating to the same standard as the original Supercoat™ Plaster System application.

If chemical free framing timber has been used, it is imperative that the maintenance of the cladding system is followed rigorously to ensure the minimum moisture ingress takes place to prevent expensive and extensive structural repair work.

As part of the Warranty conditions the finish coat(s) will need to be re-applied between 8 to 10 years as specified in the Supercoat Maintenance Guide. For exposed locations washing and re-painting may be required more frequently.

Failure to correctly maintain the system may void any long term warranties offered with the system

5.2 WARRANTY

Plastercrete AAC Panel, when installed as per this manual, is guaranteed to be free of defect in material and manufacture for 15 years (from date of completion).

The Supercoat™ plaster system is guaranteed a period of 8 years (from date of completion) to perform and meet the requirements of NZBC, where all material components of the plaster system have been prepared and installed in accordance with this manual, the Supercoat™ Technical Manual, technical specifications, carried out by a registered applicator, and where the system has been properly maintained.
