Fix these first. Cladding won&#8217;t mask a structural issue \u2014 it&#8217;ll just make it harder to reach later. Clear any loose paint, old fixings, or debris from the surface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the building sits in a designated bushfire zone, check your BAL rating and NCC requirements before you start. Some fixings and batten materials may be restricted in higher BAL zones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Never fix composite cladding boards directly to masonry or brick.<\/strong> The boards need a ventilated air gap behind them. This lets moisture drain and air move freely. Our trade partners along the Queensland coast see the same pattern on project after project. Moisture trapped behind cladding is one of the most common causes of early wear they get called back to fix.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A breathable membrane between the wall and the batten subframe is best practice on any cladding project, especially near the coast or in high-rainfall areas. It adds a second layer of protection and keeps the wall in good shape behind the boards.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Fix the Batten Subframe<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">This is the most critical stage. Get the subframe wrong, and every board above it will show it.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-batten-frame-installation-1024x683.jpg\" alt=\"\" class=\"wp-image-7026\" title=\"\" srcset=\"https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-batten-frame-installation-1024x683.jpg 1024w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-batten-frame-installation-300x200.jpg 300w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-batten-frame-installation-768x512.jpg 768w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-batten-frame-installation.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Batten direction:<\/strong> Run battens perpendicular to the boards. Horizontal cladding boards need vertical battens. Vertical boards need horizontal battens.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recommended spacing:<\/strong> 300\u2013400 mm centre-to-centre for LastElegance composite cladding. DecoGroove boards weigh up to 2.93 kg per linear metre, so spacing can tighten toward 300 mm for that profile. Check the data sheet for your specific board. Correct spacing keeps boards fully supported and keeps the install within warranty conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Air gap:<\/strong> Leave at least 20\u201325 mm between the wall surface and the back of the battens. This maintains airflow, prevents moisture from building up, and lets any rainwater that gets in drain out cleanly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here&#8217;s the step sequence for fixing the subframe:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Mark your batten positions with a chalk line. Use a tape measure to set even spacing from the top to the bottom of the wall.<\/li>\n\n\n\n<li>Check each batten with a spirit level before fixing \u2014 both vertically and across the wall face.<\/li>\n\n\n\n<li>Fix battens into the wall structure or joists using stainless steel screws. Don&#8217;t anchor into render alone.<\/li>\n\n\n\n<li>For aluminium or steel battens, use self-drilling screws rated for exterior use. Aluminium holds up much better than timber in coastal and high-UV areas \u2014 it won&#8217;t swell, split, or corrode.<\/li>\n\n\n\n<li>Step back and check the full layout once all battens are in. Every batten should sit flush. This is what makes or breaks the finished wall.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">Horizontal or Vertical \u2014 Which Should You Choose?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Both work. The choice is mostly about looks.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-horizontal-vertical-styles-1024x683.jpg\" alt=\"\" class=\"wp-image-7027\" title=\"\" srcset=\"https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-horizontal-vertical-styles-1024x683.jpg 1024w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-horizontal-vertical-styles-300x200.jpg 300w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-horizontal-vertical-styles-768x512.jpg 768w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/composite-cladding-horizontal-vertical-styles.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Horizontal installation is the standard for most residential and commercial facades across Australia. It gives a classic weatherboard profile that suits a wide range of projects and has a more traditional look that clients recognise. Vertical installation suits modern and industrial designs \u2014 it&#8217;s a common choice on commercial fit-outs where strong vertical lines are part of the brief.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical difference is just the batten direction. The subframe must always run perpendicular to the boards, whichever way you go.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Is the Laying Pattern and How Does It Affect the Job?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The laying pattern is how the boards sequence from the base of the wall up.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Always start at the bottom and work upward. Each board sits over the one below it, so water sheds away from the wall rather than behind it. For LastElegance composite cladding boards, the male-female interlocking system locks each board into position as you climb. Set the first cladding board dead level at the base of the wall, and every board above takes its cue from it. The system removes the guesswork on alignment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Installing the Cladding Boards<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Work from the bottom up. A level first board makes every board after it easier and faster to place.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/how-to-install-composite-cladding-panel-1024x683.jpg\" alt=\"\" class=\"wp-image-7028\" title=\"\" srcset=\"https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/how-to-install-composite-cladding-panel-1024x683.jpg 1024w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/how-to-install-composite-cladding-panel-300x200.jpg 300w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/how-to-install-composite-cladding-panel-768x512.jpg 768w, https:\/\/www.lastelegance.com\/au\/wp-content\/uploads\/2026\/06\/how-to-install-composite-cladding-panel.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Fix the starter clip<\/strong> to the batten at the base of the wall. This holds the bottom edge of the first board in position.<\/li>\n\n\n\n<li><strong>Set the first board.<\/strong> Mark your starting height and snap a chalk line across the wall \u2014 don&#8217;t use the ground as your reference, it&#8217;s rarely level enough. Seat the board into the starter clip and check it with a spirit level. Even 2\u20133 mm out of level here will compound across the whole wall, so take your time.<\/li>\n\n\n\n<li><strong>Clip the board to the batten<\/strong> using the stainless steel clips supplied. No screws go through the board face.<\/li>\n\n\n\n<li><strong>Slide the next cladding board<\/strong> down over the tongue of the board below. Push it firmly until it clips into place.<\/li>\n\n\n\n<li><strong>Continue up the wall<\/strong>, checking level every 3\u20134 boards.<\/li>\n\n\n\n<li><strong>Measure and cut remaining cladding boards<\/strong> to fit as you reach windows, door openings, and the edges of the wall. Leave expansion gaps at each board end \u2014 see the expansion gap section below.<\/li>\n\n\n\n<li><strong>Fix the top board last<\/strong>, trim to the correct height, and fit the top trim strip.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">No surface screws means no visible fixings. The wall looks clean from the first board to the last. Installation videos are available from our team if your crew wants a full walkthrough before starting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Colour looks different on site than it does on screen. Before you order the full run, <strong><a href=\"https:\/\/www.lastelegance.com\/au\/contact\/\">request a few free samples<\/a><\/strong> to check them under real light.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cutting Boards to Fit<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A mitre saw handles most crosscuts \u2014 trimming boards to length around windows, door frames, and at the top of the run. A circular saw is better for longer lengthwise cuts when you need to rip a board down to fit under a sill or along a roofline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Composite boards cut cleanly with standard carpentry saw blades. Cut edges don&#8217;t need sealing. A fine-tooth blade reduces chipping on the board face, which matters on visible cuts near windows and corners.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Measure twice before you cut. Fit corner trims and fascia boards over any exposed cut edge \u2014 they cover minor variation and give the job a neat finish throughout.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fitting Corner Trims and Finishing Pieces<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Corner trims and finishing strips are what take a good install and make it look professional. Every exposed cut edge on a cladding project should be covered.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The full trim system for a LastElegance composite cladding installation includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Top and bottom trim strips<\/strong> \u2014 cap the top edge and finish the base of the wall<\/li>\n\n\n\n<li><strong>Corner trims<\/strong> \u2014 cover both external and internal corners cleanly<\/li>\n\n\n\n<li><strong>Angle brackets<\/strong> \u2014 secure the trim to the subframe<\/li>\n\n\n\n<li><strong>Post caps and post skirts<\/strong> \u2014 for designs with posts<\/li>\n\n\n\n<li><strong>Post edge trims<\/strong> \u2014 finish the edge return at corners or post positions<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Cut all trim pieces to length on site using the same saw you use for boards. Because the trim system is made to match the cladding range, profiles and colours line up \u2014 no mixing parts from different suppliers, no colour mismatches to explain to the client.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every accessory in this system has its specs listed in our <strong><a href=\"https:\/\/www.lastelegance.com\/au\/composite-cladding\/\">full product catalogue<\/a><\/strong>. That means no hunting through separate spec sheets.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Expansion Gaps \u2014 Why Australia Is Different<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most installation guides mention expansion gaps. Few explain why they matter more here than in Europe.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Composite material expands and contracts with temperature. In the UK or northern Europe, the thermal swing a board sees across a full year is modest. In Australia \u2014 especially inland Queensland, WA, or the Northern Territory \u2014 surface temperatures on a north-facing wall can push past 60\u00b0C in summer. That&#8217;s a much wider thermal cycle than most European product specs are built around.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Leave a gap at each board end and wherever boards meet a fixed element<\/strong> \u2014 window frames, door frames, posts, and corner trims. For LastElegance composite cladding boards, treat the minimum recommended gap as exactly that: a minimum, not a target. In warmer climate zones, go wider.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Skip the gaps, and the boards push against each other during thermal expansion. The result is bowing, buckling, and pressure on the clip fixings. Moisture also collects more readily in a tight board run, and that affects durability over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Under the LastElegance 20-year warranty, missed expansion gaps count as incorrect installation \u2014 and that&#8217;s not covered. It&#8217;s simple to get right during the build. It&#8217;s expensive to fix after.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a full breakdown of what to watch for, see our related guide: <a href=\"https:\/\/www.lastelegance.com\/au\/composite-cladding-installation-mistakes\/\">common mistakes when installing composite cladding<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1782287028053\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Can you use normal screws for composite cladding?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Corrosion-resistant screws are the right choice for fixing battens to the wall \u2014 stainless steel screws are standard in Australian coastal and humid conditions. For the boards themselves, the hidden clip system means no screws go through the board face at all. The surface stays clean.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1782287028940\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Do you need council approval to install cladding in Australia?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>In most cases, adding or replacing cladding on an existing building doesn&#8217;t need a Development Application. But this varies by state and local council \u2014 always check before you start, especially on commercial buildings or heritage-listed properties.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1782287029412\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Do composite cladding boards need a moisture barrier behind them?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>A breathable membrane is best practice, particularly on masonry or brick walls in high-rainfall or coastal areas. The batten subframe already creates an air gap that supports ventilation and drainage \u2014 the membrane adds another line of defence.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1782287029988\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How long does it take to install composite cladding?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>For a straightforward feature wall or single-storey section, two people working with the LastElegance clip system can usually finish in a day. Corners, windows, and roof lines all add time, so a full house re-clad will take longer.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1782287030572\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Is there a difference between installing regular and slatted composite cladding?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The core process is the same \u2014 battens, clips, bottom-up sequence. The key difference is board width and the visual gap between boards on slatted profiles. This affects your linear metre count and how corner trims are fitted at each end.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1782287109717\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Does incorrect installation affect the warranty?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes. The 20-year warranty covers normal use. Damage from incorrect installation \u2014 missed expansion gaps, wrong fixings, or unsupported board spans \u2014 is not covered.
