4257MF METALCRAFT FIRE RESISTANT INSULATED PANEL SYSTEMS

1. GENERAL

If you have pre-customised this work section using the "questions and answers" provided as part of the downloading process, it may be necessary to amend some clauses to suit the final project-specific version.

The section must still be checked and customised to suit the project being specified, by removing any other irrelevant details and adding project-specific details and selections.

This section relates to the fabrication, supply and installation of prepainted steel clad, insulating panels and cladding system for ambient controlled temperature buildings using:

- ThermoPanel FR fire resistant insulated wall and ceiling panels

- ThermoSpan FR fire resistant insulated roof and wall cladding panels

- Flameguard fire resistant insulated wall and ceiling panels

Modify or extend the above description to suit the project being specified.

ThermoPanel FR, when used in a wall cladding application only, is fire rated where the maximum height is less than 9.1m.

Flameguard, used in a wall cladding application only, is fire rated.

Where the panel structure is not self-supporting, cross reference to the relevant structural sections to ensure the thermal integrity of the completed building is not compromised.

It is important to ensure that all personnel on site have access to accurate, up to date technical information on the many products, materials and equipment used on a project. In most cases individual products are not used in isolation, but form part of a building process. Also a particular manufacturer's and/or supplier's requirements for handling, storage, preparation, installation, finishing and protection of their product can vary from what might be considered the norm. Access to technical information can help overcome this potential problem.

Warranties

Supplier and manufacturer warranties are those that are freely offered by the supplier or manufacturer. They are usually in their standard form and subject to their terms and conditions. Check the general section 1237 WARRANTIES for the date of commencement of warranties; which is normally practical completion of the contract. Refer to the chosen conditions of contract as it may also contain information on warranties. Not all product applications will receive a standard warranty. Refer to Metalcraft Insulated Panel Systems for further details and conditions that will apply to specific project.

1.4 WARRANTY - INSTALLER/APPLICATOR

Provide Installer's warranty.

5 years: For workmanship

Refer to the general section 1237 WARRANTIES - INSTALLER for additional requirements.

1.5 WARRANTY - MANUFACTURER/SUPPLIER

Provide Metalcraft Insulated Panel Systems warranty.

15 years: For materials

Refer to the general section 1237 WARRANTIES - MATERIALS for additional requirements.

Requirements

1.6 QUALIFICATIONS

All installation and sealing of the panels by an installer accredited by Metalcraft Insulated Panel Systems.

1.7 SHOP DRAWINGS

Provide shop drawings to show, but not be limited to:

- fully dimensioned elevations of all elements

- complete details of construction, connections and all support systems

- dimensions of all typical elements and of any special sizes and shapes

- provision for the exclusion and/or drainage of moisture

- jointing details and method of fixing between individual elements and between this installation and adjacent work

- a full schedule of materials, finishes, componentry, hardware and fittings.

Refer to 1235 SHOP DRAWINGS for submission and review and the provision of final shop drawings.

Add further detail on the precise form and extent of shop drawings where appropriate.

On some projects more specific and extensive requirements for shop drawings should be set, to ensure there will be sufficient information to properly review the proposed work. On other projects there may be no need for shop drawings; instead you might request a confirming schedule of panel types, sizes and finishes.

Performance

1.8 DESIGN REQUIREMENTS

Structural design to be supported by a Producer Statement prepared by a Chartered Professional Engineer. Refer to Metalcraft Insulated Panel Systems data for information relating to panel spans. Loading parameters to comply with the methods described in NZS 3404.3.3 and 3.4.

Refer to SELECTIONS.

Refer to Metalcraft Insulated Panel Systems at commencement of design process to ensure the panel system is designed to suit specific project in terms of panel selection, fixings, and architectural details. On larger projects you will need to set out the requirements for the design of any supporting systems and the structural integrity of the panels themselves. Note that in such a case it would be necessary to set out the required design parameters (acceptable deflection, site wind loadings and the like) and the proposed system for approving the submitted design.

Note that in using the next two clauses you are setting a standard of performance for the contractor to meet. Specifiers should therefore consider adding some means of confirming (say by testing or certification) that the performance criteria will be or have been met.

1.9 FIXINGS, WIND

Design and use the fixings appropriate for the wind loads on various elements as given by AS/NZS 1170.2. Refer to SELECTIONS.

1.10 FIXINGS, EARTHQUAKE

Use fixings and methods capable of sustaining the loads appropriate to the area as required by NZS 1170.5.

This clause might only apply where the method of fixing the panels is required, by design or regulation, to comply with the earthquake requirements of NZS 1170.

1.11 FIRE SAFETY

ThermoPanel FR and ThermoSpan FR insulated wall, ceiling and roof panels comply with NZBC C/AS1-AS7, 4.17.2 Foamed plastics and exposed combustible insulating materials, AS 1530.4, AS 2122.1 and ISO 9705.

When tested to ISO 9705, ThermoPanel FR and ThermoSpan FR panels provide Group Numbers in accordance with NZBC C/AS1-AS7, 4.17.1 Table 4.1 Surface finish requirements, as follows:

3. EXECUTION

Conditions

3.1 INSTALLATION

All work by competent and experienced installers, who are currently approved by Metalcraft Insulated Panel Systems in accordance with the stated requirements and the approved shop drawings. All panel manufacture and installation under the control and supervision of a nominated representative of Metalcraft Insulated Panel Systems.

3.2 METAL FINISHES

All metal finishes applied by applicators currently approved in writing by the coating manufacturer.

3.3 TOUCH-UP

In situ touch up of factory applied finishes is not to be permitted unless a trial repair is subsequently approved in writing. Replace all other panels with a damaged finish.

Modify or delete the above clauses on quality standards where a formal quality control system is not required or justified.

3.4 HANDLE AND STORE

Handle and store pre-finished panels and materials so that no damage will be done to the forms, materials, or finishes.

3.5 UNLOAD

Unload, handle and store preformed and pre-finished panels in accordance with the Metalcraft Insulated Panel Systems stated requirements. Use only polystyrene or other soft packing when stacking panels.

3.6 DO NOT DELIVER

Do not deliver to site any panels or elements which cannot be immediately unloaded into suitable conditions of storage.

3.7 PROTECTION

Avoid distortion of panels or elements during transit, handling and storage. Prevent pre-finished surfaces from rubbing together. Prevent contact with mud, plaster and cement, or with dissimilar metals.

3.8 DO NOT USE

Do not use adhesive tape, film, papers, or sprayed protective coatings, or masking tape, which might become bonded after exposure to sun or weather. Remove any temporary protection after installation. Remove any protective coating residues immediately.

3.9 RAW EDGES

Seal cut edges of panel skins using a proprietary brush on lacquer.

Refer to the panel manufacturer's requirements. Sealing of cut edges is generally only required for more extreme environments, to prevent the early onset of corrosion.

3.10 GALVANIC CORROSION

Avoid run-off from any copper or brass systems, or unpainted lead flashings. Electrically isolate any large areas of stainless steel from the panel surface. Where dissimilar materials might be in contact, provide a separation barrier.

Generally the paint on the panel skin provides sufficient separation against galvanic corrosion. However check with the panel manufacturer when there is any doubt. In particular special attention might be needed to any rivets or fixings which penetrate the protective coating.

Assembly

3.11 FABRICATION

Do not start fabrication until shop drawings and erection drawings have been reviewed and material samples approved.
