They hold the cladding 10 mm off the membrane so the cavity can drain and ventilate. 45 mm x 1.2 m x 10 mm, pack of 50.\u003c\/p\u003e\n\u003ch3\u003eWhat a drained cavity actually buys you\u003c\/h3\u003e\n\u003cp\u003eCladding fixed hard against a wall wrap has nowhere for incidental water to go and no air movement to dry it. A batten turns that contact into a cavity, and the cavity does three jobs at once: it drains, it ventilates, and it separates the cladding from the frame thermally. On a metal roof it also keeps the dew point on the underside of the roof sheet rather than on the membrane, which is where the drips come from.\u003c\/p\u003e\n\u003ch3\u003eStrong enough to fix through\u003c\/h3\u003e\n\u003cp\u003eCompression resistance is 500 kPa, it takes normal foot traffic, and it resists impact from cladding installation and screw pull. Thermal resistance is R0.15 in situ, and long term heat resistance is 90 degrees.\u003c\/p\u003e\n\u003ch3\u003eDouble up for 20 mm\u003c\/h3\u003e\n\u003cp\u003eTwo thicknesses give a 20 mm gap, which is what the NCC 2022 air gap and ventilation provisions call for in Volume One F8D5 and J4D3 and Housing Provisions 10.8.3 and 13.2.2. If you want 20 mm in one piece and a full R0.2 thermal break, use \u003ca href=\"\/products\/ametalin-thermalcav-drainage-battens\"\u003eThermalCav Drainage Battens\u003c\/a\u003e instead.\u003c\/p\u003e\n\u003ch3\u003eOn site\u003c\/h3\u003e\n\u003cp\u003eNo temporary fixings needed. Clean and dry the framing, peel the liner, centre the batten on the member, press it home by hand and get the cladding on without delay. Runs vertically or horizontally. Termite, mould and mildew resistant, and UV and fire rated.\u003c\/p\u003e","brand":"Ametalin","offers":[{"title":"45 mm x 1.2 m x 10 mm, pack of 50","offer_id":45385992011958,"sku":"CDB-451200","price":287.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3995\/3590\/files\/Ametalin-Cavity-Drainage-Battens_1024-x-1024-px.jpg?v=1787845318","url":"https:\/\/awbm.com.au\/products\/ametalin-cavity-drainage-battens","provider":"AWBM","version":"1.0","type":"link"}
