Pack of 50 strips.\u003c\/p\u003e\n\u003ch3\u003eWhy a steel frame needs one\u003c\/h3\u003e\n\u003cp\u003eSteel conducts heat roughly a thousand times better than timber. A steel stud that touches both the lining and the cladding carries heat straight through the wall regardless of how much batt sits between the studs, and the cold line it creates on the inside face is where condensation shows up first. The NCC requires an R0.2 thermal break in these situations. This strip is tested at R0.25 to ASTM C518, so it clears the requirement with margin.\u003c\/p\u003e\n\u003ch3\u003eDual density, which is the useful part\u003c\/h3\u003e\n\u003cp\u003eA high density XPE face gives the cladding a firm base to fix against, and a medium density core underneath conforms to an imperfect frame. A single density foam has to pick one of those and give up the other.\u003c\/p\u003e\n\u003ch3\u003eIt also drains\u003c\/h3\u003e\n\u003cp\u003eThe strip lifts the cladding off the membrane, which creates a drainage plane for water to escape and lets the wall breathe. It is termite, mould and mildew resistant, and it seals around membrane fixings.\u003c\/p\u003e\n\u003ch3\u003eWhich strip to buy\u003c\/h3\u003e\n\u003cp\u003eThis is the XPE foam version, R0.25. Where the construction has to be non-combustible, use the \u003ca href=\"\/products\/ametalin-non-combustible-thermalbreak-strip\"\u003eNon-combustible ThermalBreak Strip\u003c\/a\u003e instead. If the job also needs a 20 mm drained and ventilated cavity, look at \u003ca href=\"\/products\/ametalin-thermalcav-drainage-battens\"\u003eThermalCav Drainage Battens\u003c\/a\u003e, which do both at R0.26.\u003c\/p\u003e\n\u003ch3\u003eOn site\u003c\/h3\u003e\n\u003cp\u003eCuts to length with a knife. Peel the liner, centre the strip on the framing member and press it home, then get the cladding on without delay. Surfaces have to be clean and dry.\u003c\/p\u003e","brand":"Ametalin","offers":[{"title":"43 mm x 2.75 m x 12 mm, pack of 50","offer_id":45385990799542,"sku":"TBS-432750","price":526.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3995\/3590\/files\/Ametalin-R0.25-ThermalBreak-Strip_TBSTRIP-432750_02_1024-x-768px.jpg?v=1787845244","url":"https:\/\/awbm.com.au\/products\/ametalin-thermalbreak-strips-r025","provider":"AWBM","version":"1.0","type":"link"}
