{"product_id":"trade-select-firesark","title":"Trade Select FireSark®","description":"\u003cp\u003eTrade Select FireSark is a non-combustible roof sarking and wall wrap built for bushfire areas. E-glass fabric bonded to a 97% reflective aluminium foil with a fire resistant adhesive, 1350 mm x 30 m covering 40.5 m².\u003c\/p\u003e\n\u003ch3\u003eNon-combustible, not just fire retardant\u003c\/h3\u003e\n\u003cp\u003eBoth the fibreglass fabric and the aluminium foil are not deemed combustible, flammability index is 1, and ignitability, spread of flame and heat evolved indices are all 0 with smoke developed at 2. It complies with AS 3959-2018 for all Bushfire Attack Levels including Flame Zone, and meets the Deemed-to-Satisfy provisions for non-combustible construction. On a BAL rated job that combination is the reason to specify it.\u003c\/p\u003e\n\u003ch3\u003eVery strong for a membrane\u003c\/h3\u003e\n\u003cp\u003eTensile strength is 58 kN\/m in the machine direction against a 13.0 minimum, and 26 kN\/m lateral against a 10.5 minimum. Extra Heavy duty to AS\/NZS 4200.1:2017. That is a large margin, and it matters on a site where the sarking may sit exposed before cladding.\u003c\/p\u003e\n\u003ch3\u003eBarrier and reflective performance\u003c\/h3\u003e\n\u003cp\u003eClass 2 vapour barrier at 0.003 µg\/N·s, water barrier and air barrier. The foil face is 97% reflective with an emittance of 0.03, so it needs an air gap in front of it to contribute. It is electrically conductive, so keep it clear of wiring.\u003c\/p\u003e\n\u003cp\u003eFull figures are in the table below.\u003c\/p\u003e","brand":"Ametalin","offers":[{"title":"Default Title","offer_id":45225010266294,"sku":"SQ4207071","price":210.56,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0732\/3995\/3590\/files\/FireSark-Product-Shot-1024x1024-Trade-Select.webp?v=1782756327","url":"https:\/\/awbm.com.au\/products\/trade-select-firesark","provider":"AWBM","version":"1.0","type":"link"}
