THERMAL MOVEMENT Any wood composite products will expand and contract longitudinally with changes in temperature. The amount of expansion varies according to the amount of changes in temperature. Although thermal movements are reversible, these movements due to temperature change may vary by up to 2mm per meter during the installation process. M&B Lining boards that have been exposed to direct sun for several hours, prior to installation may have expanded more than those boards left in the shade. When installed, the hotter boards will contract more than the cooler boards that were left in the shade prior to installation. It is important to maintain an average consistent temperature for all boards as they are being installed. DO NOT expose boards to direct sunlight prior to installation. (See site storage.) NOTE: Where M&B Lining boards are to be screw fixed, holes must be pre-drilled before fixing. The clearance hole to be drilled must be slightly greater than the outside screw thread diameter. Screw fixings must be minimum 5mm but maximum 25mm away from board edges and ends. FRAMING CONSTRUCTION REQUIREMENTS M&B Lining boards may be fixed to seasoned timber or steel stud framing members or to a proprietary batten system. The lining is to be set at no more than 450mm centres for out of weather applications and 300mm for Soffit and eaves lining in urban and non-cyclonic wind load areas. For higher wind-load areas may be accommodated by reducing batten spacing. In common with all ceiling the adequacy of a proposed installation should always be checked by a qualified engineer. Battens, noggins and trimmers must have a face not less than 45mm for timber and 38 mm for steel. TIMBER FRAMING Timber battens to which all M&B Linings to be fixed must comply with AS684 Timber Framing Code or AS720. timber structures: Design Methods. It is important to use adequately seasoned timber to minimise shrinkage and associated building movement. INSTALLATION TIPS AND REQUIREMENTS All M&B Lining products can be worked with ordinary woodworking tools such as: Circular Saw Cordless Drill Crosscut Mitre Saw Level & Chalk Line Carpenter s Square Tape Measure Brad Gun SITE STORAGE & PRODUCT HANDLING. M&B Lining boards should be delivered and immediately stored undercover on a dry and flat surface supported at max 450mm centres. 2. M&B Lining boards should be stored under cover and protected from the elements (including direct sunlight and rain) until ready to install. Keep packs strapped until ready to install. 3. When handling M&B Lining boards take care to avoid scratches, nicks and other damage to the boards. 4. When removing M&B Lining boards from the pack, do not slide boards against each other, lift the boards and set them down carefully. 5. M&B Lining boards should be carried on their edge for better support by more than one person when dealing with long lengths. NOTE: To ensure long- term performance, we recommend that a professional trade person carry out the installation. The installation MUST be carried out in accordance with these instructions including the use of all trims and accessories. STORAGE REQUIREMENTS Under Cover Max 450mm centres Max 450mm centres STEEL FRAMING Steel framing must comply with AS/NZS 4600: Cold-Formed Steel Structure or AS 3623: Domestic Metal Framing. Where steel framing members are specified, use only corrosion resistant galvanized steel framing. Specific instructions for fixing to steel frames are included where appropriate. Thermal breaks are required for steel framed buildings and should be installed between the ceiling/soffit and lightweight steel CFS stud and or top hat sections. Thermal break products should have a minimum R-Value of 0.2 or less. ADHESIVES Ensure that you ONLY use Soudal SMX35 or Sikaflex FC adhesives, available from your nearest M&B store. INSULATION When installing M&B Linings beneath a gable tin roof and/or flat roofs with minimal space between the roof and lining, GI Reflecta-Cell insulation (or product with a similar R value) MUST be used between roof and the lining. Not only will this aid in reducing condensation but will also increase the performance of the lining by reducing radiant heat absorption into the lining thus improving the environment under the lining, making it cooler in areas such as alfresco areas.

This can be done running a string line across all joists and adjust as required until level. Ensure first board is straight and pin through face on starting edge of the first board. 2 Once you have established a starting point, leaving a minimum 5mm expansion gap around walls, apply Soudal SMX35 or Sikaflex FC along each joist with an 8mm bead working no more than 3-4 lining boards ahead to avoid silicone curing before all boards are installed.

It is best to complete cleaning when the board surface is cool to prevent cleaners from drying/ evaporating on the board surface. 4 Double pin each joist on diagonal minimum 5mm apart to avoid fracturing edge. 5 8mm bead silicon adhesive as specified along every Joist Ensure when pinning lining board to joist that the pin is inserted as far away from the edge of the board as possible to avoid splitting the tongue To maintain and protect the colour and extend the life of your M&B Lining board, regular simple maintenance is recommended. Conducting routine 6-monthly maintenance inspections are recommended to determine if re-coating is required. For re-coating refer to manufacturer s care and maintenance instructions. 5mm GENERAL DIRT AND DEBRIS Clean with warm soapy water only. Apply with a damp sponge, soft broom or mop. Do not soak. Remove any salt build up immediately with damp sponge, soft broom or mop.

4 SHIPLAP FIXING WITH SCREWS Please note that the following instruction is also applicable for CL6728/CL702/CL400/CW NOTE: Pre-drilling is essential when using screws. All screws are minimum 5mm but maximum 25mm away from board ends. Only work 2-3 boards ahead. Ensure product is stretched out to avoid sagging, working from one end to the other end along the length. Silicone based adhesives as specified* INTERNAL: 450mm centres maximum EXTERNAL SOFFIT/EAVES: 300mm centres maximum 8mm bead silicon adhesive as specified along every Joist Screw to suit structure 2a. Position the second ceiling board into the groove of the first board and temporarily hold it in place. 2b. Use countersunk head screw to screw fix the second board onto the joist. 2c. Repeat this step until the ceiling is fully installed. 2d. Should, the last board to be installed not be full width, trim to required width. Then fit board and face fix the outer edge. These fixings should be covered by fitted trims. a. Joists span is set to no more than 450mm centres for internal application and 300mm centres for external soffit/eaves. b. Ensure all joists are level before commencing installation. This can be done running a string line across all joists and adjust as required until level. c. To establish the starting point of the lining, use a string, spirit or laser level to ensure that the lining being installed will be both straight and square to any fixed structures. The straightness and squareness of the lining should be checked periodically during installation to avoid any creep. d. Apply Soudal SMX35 or Sikaflex FC along each joist with an 8mm bead working no more than 3 boards ahead, to avoid silicone curing before all boards are installed. e. Leaving a minimum 5mm expansion gap around walls, use countersunk head screw to fix the first ceiling board through the edge both sides, be careful not to break the tongue of the starting board. f. Ensure the screw head is flushed with board surface to allow the adjacent board to slide in. 3 3a. Use appropriate cornice or trim bead to finish off as necessary. 3b. In the case of Innowood Qube profile (CL6728) a trim needs to be placed firstly around the wall so the Qube profile butts up against this (allowing for a minimum 5mm clearance gap) and then final trim added as per normal. This removes the staggered appearance of the profile against the wall. Trim is placed flat against the wall. Allow a minimum 5mm clearance gap between lining and wall trim. Final Trim is placed into position. IMPORTANT: Allow for a minimum 5mm expansion gap around walls. NOTE: These Guidelines are subject to modifications without notice.
