3 For smooth cuts, use a circular saw. Joint Sealant and Board Adhesive. Class A polyurethane sealant should be installed with strict adherence to manufacturers installation instructions. Apply the clad seal tape to the primary 160mm top Hat. The seal can be applied to the mounted top hat in-situ or horizontally before it is fixed to the purlins. Ensure the seal is applied to the centre of the purpose designed seal channel on the primary 160mm top-hat. can also be cut easily using a normal hand saw. The edge of can be planed or smoothed with an electric planer, rasp or file, or conventional papers if sanding is required. For making holes in the board, use a standard drill tip. Do not use hammer action. comprises of Multiboard panels used in a specialised sub system that incorporates cold formed section steel top hat sections, horizontal backing strip and Multiboard butyl gasket tape 50mm BFT-3/25. Primary top hat - 160mm x 35mm x 1.0mm BMT. When the Expressed Panel Facade System is to be used, the following needs to be considered: Wind Loads Insulation / Sarking Coating Systems Control Joints Maintenance Substrate Structure Panel Layout The layout of primary and intermediatel top hats are to be as per design engineers specifications. Refer to the table below as a guide for wind load design. Within 1 Spacing of building edge Fastener Spacing Elsewhere Within 1 of building edge Elsewhere Determine the panel layout then mark out the centre point of each top hat on the purlins. When fastening use recommended Multiboard (SMF 30-8-C4) fasteners. Where fasteners are to be countersunk, the depth must be controlled by a gauge to restrict the fasteners head depth to no more than the face of the board. Fasteners must have the appropriate level of durability for the intended use, particularly in areas subject to salt spray, such as coastal areas. Adhesives must not be used to attach sheets to the frame. As a guide to the classification please refer to the table below: > 400m from ocean or from severe marine influence. Severe marine influence and up to 400m from marine environment. AS 3566 Class 3 AS 3566 Class 4 - Stainless Steel. Fasteners must not be overdriven, as this can reduce the holding capacity of the sheet. Intermediate top hat - 50mm x 35mm x 1.15mm BMT. Position the top hats according to the predetermined marked spacing's and ensure they are vertical (check with a spirit level). Screw Head must be flush with or approximately 1mm below the Multiboard sheet surface Pre-painted horizontal backing strip - 10mm x 0.55mm BMT. Fix the top hats to the purlins using appropriate fasteners ensuring both legs are fixed to the purlin to minimise flexing of the top hat. Recommended fasteners are to be placed no closer than 40mm from the edge of the Panels and no closer than 100mm from any corner. Multiboard Clad Seal Tape CS-3/25.

4 Pre-mark, holes in the expressed panels as set out in the table below. 40mm 100mm mm Insert the backing strip behind the top of the board. Fasteners are left loose to allow for the insertion of the backing strip. Recommended clad seal tape Main Backing Strip After the backing strip is in position, the top row of fasteners need to be tightened to draw the sheet and backing strip against the top hat, completing the seal. When installing the next layer of, apply a bead of the appropriate sealant to the top of the backing strip and then rest a sheet on the purpose designed 3mm edge of the backing strip. fixing details bottom layer of board Fix the bottom row of expressed panels allowing a 15mm overlap of the recommended clad seal tape. Leave the top row of fasteners in the loose to facilitate the insertion of the backing strip to the board. The backing strip joint has been designed to overlap whilst retaining a flush fit behind the board. Recommended clad seal tape Position the sheet ensuring all joints are 10mm. Fasten the panel to the top hats using the recommended fasteners. fixing details bottom layer of board Bead of Sealant Panel Backing strip joints must overlap the nearest top hat and be sealed with two beads of an appropriate sealant to ensure a water tight joint. 2 Beads of Sealant Panels to overlap seal minimum of 15mm Backing strip overlaps at the nearest top hat by at least 50mm Continue with this installation process until all sheets are installed. All counter-sunk fasteners, must be covered with a fine acrylic modified render (patch), such as MB T7 Patch Filler. Use the backing strip to space the vertical joint of the successive sheet ensuring a uniform 10mm space between the sheets. Prepare the backing strip for installation by applying an appropriate sealant to the bottom (9mm) edge of the backing strip or by applying the sealer to the top edge of the sheet. Ensure that a bead of at least 8mm in diameter is applied.

5 Remove any rough edges from the screw holes using a scraper. Fill the pre-drilled holes with the recommended MB T7 Patch Filler. Two separate applications may be required to allow for any shrinkage in the patch ensuring any pinholes are filled and the screw heads are water tight.

6 Vertical Construction Joint Against Existing Structure Existing Structure 40x40mm BMT backing angle fixed to existing structure 50mm Sarking Polyurethane Sealant Expressed Panel Facade System is manufactured from woven glass fibre, recycled wood fibres (50%), magnesium cement, and additives which catalyse the cementing action. As manufactured, the product will not release airborne dust, however during drilling and sanding operations, glass fibres and fine dust may be released. When using power saws in a confined space, dust extraction equipment is recommended to control dust levels. If power tools are used externally, wear an approved P1 or P2 dust mask, respirator and safety glasses. No special safety precautions are necessary when handling or working with Multiboard.
