b"1.4 General RequirementsThe following installation instructions and guides are in addition to local and state regulations and the requirements of the National Construction Code (NCC). Weathertex provides construction detail drawings which should be used in conjunction with the instructions in this installation manual. NOTE: All diagrams in this installation manual are for demonstration purposes only. Diagrams may omit some components for clarity. Deviation from standard applications and requirements detailed in this Installation Manual or supplementary Weathertex Construction Details may void the manufacturer's product warranty. The product specific installation instructions in this manual are applicable to steel and timber frames for both direct fix and cavity systems. Preparation steps must be followed for direct fix to timber frame, ventilated cavity construction and steel frame construction.1.4.1STORAGE AND HANDLINGWeathertex products should be stored flat, under cover and on timber bearers spaced at maximum 600mm centres. When storing Weathertex outside, keep the stack clear of the ground and cover with waterproof materials to prevent water staining.NOTE: Weathertex factory stretch wrap is not designed to keep stored product weatherproof and should not be relied upon for primary weather protection. Anodised aluminium products should be stored in a dry and flat position away from any potentially corrosive or incompatible materials. Timber or soft bearers at a distance no more than one metre apart should be used to support the product. Continuous exposure to moisture will promote corrosion. Metal edges and cut corners of the product can be sharp and may cause personal injury if not handled safely. Wear eye protection, gloves and protect skin when possible and when cutting avoid air borne metal fragments.1.4.2CUTTING AND WORKING WITH WEATHERTEXWeathertex products are easy to cut and shape with a normal hand or power saw. Primelok Weatherboards should be cut individually to protect the aligning spline. Where required, edges may be trimmed with a smoothing plane or sandpaper. Holes are easily drilled with high speed drills or clean cutter bits. For best results break cut edges with a 2mm chamfer. Clean all dust from flashing as work progressed, as it may mix with water and create a brown runoff. Cut edges, holes and countersinks must be re-primed with a high quality tannin blocking exterior timber primer (water or solvent based). Excluding our Natural range.The normal health and safety precautions should be taken when working with wood panel products. Machining equipment should be fitted with dust collection devices and used in well ventilated areas. Follow good hygienic and housekeeping practices. Wood dust can be vacuumed, shovelled or swept to avoid accumulation. If dust levels exceed Safe Work Australia Standards the wearing of a dust mask (AS 1715 and AS 1716) and safety glasses (AS 1337) is recommended. Storage and work areas should be adequately ventilated. A Safety Data Sheet is available for download on the Weathertex website: weathertex.com.au 1.4.3SITE, FOUNDATION AND FRAMINGFoundation design must comply with AS 2870 Residential Slabs and Footings - Construction and the National Construction Code (NCC). Timber or steel frames shall comply with the NCC. Where applicable, timber frames shall be constructed in accordance with Australian Standard 1684 - Residential Timber - Framed Construction. Steel frames must be erected in accordance with the manufacturers requirements. Frames shall be straight and true with studs at a maximum of 600mm centres. Timber shall be seasoned, as unseasoned timber is prone to shrinkage and can cause sheets and frames to move.1.4.4GROUND CLEARANCESLower framing timbers must be isolated from ground moisture by suitable damp-proof courses (DPC) or termite shielding. Similarly, weatherboards must not be placed in direct contact with masonry, brickwork or concrete. Where necessary, use strips of Alcor to isolate the materials. The bottom edge of weatherboards must be kept clear of paved surfaces by a minimum of 100mm and a minimum of 225mm for unprotected ground (i.e. grass, gardens etc). Weatherboards must extend a minimum of 50mm below the bearer or lowest horizontal part of the of suspended floor framing for a suspended floor system. The grade of adjacent finished ground must slope away from the building to avoid the possibility of water accumulation. Typically this is a minimum slope of 50mm over the first metre, however please refer to the minimum slope required from local building codes and regulations. Weathertex must not be installed in wet areas and where it comes in contact with standing water.NOTE: To comply with termite protection provisions a greater clearance may be required.
