Pallets carry 24 rolls at every thickness in the range, so coverage per pallet falls as the quilt gets deeper: 230.98m² at 140mm against 406.08m² at 80mm from the same footprint. On a full building that changes the number of deliveries, the storage space needed on site and the number of lifts to get it up.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eEach roll measures 8.02m by 1200mm and covers 9.62m². Declared thermal conductivity is 0.040 W\/mK, giving a thermal resistance of 3.50 m²K\/W, and water vapour resistivity is 5.00 MNs\/g.m. Published embodied carbon is 1.21 kgCO2e\/m² across stages A1 to A3 and 1.60 kgCO2e\/m² across A1 to C4.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe binder is worth a mention at this depth. FactoryClad Rolls use ECOSE® Technology, a plant-based binder with no added formaldehyde or phenol, which leaves the quilt soft to handle and generates low levels of dust and volatile organic compounds. Knauf hold the Eurofins Gold Certificate for Indoor Air Comfort on the back of it. Feeding a 140mm roll into a cavity overhead is a bulkier job than handling a slim one, and a full day of it is a good deal more comfortable with a low-dust product than a harsh one.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eInstallation follows the standard build-up: liner sheet fixed first, quilt laid over it, spacer system brought up to compress it into the cavity, outer sheet fixed last, all to Knauf Insulation's guidance and the cladding system manufacturer's details. It is not fitted between purlins or side rails in the way a frame roll would be. 140mm suits new-build twin-skin roofs and walls, standing seam roofs, and over-roofing or over-cladding work where a new outer skin and spacer system are going on over an existing building. The U-value belongs to the whole assembly, so have it calculated to BS EN ISO 6946:2017 or BS EN ISO 10211:2017 with BR443:2019 for the actual system.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eKey Benefits of Knauf FactoryClad Roll 40:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThermal resistance of 3.50 m²K\/W at 140mm.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eDeclared thermal conductivity of 0.040 W\/mK.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEuroclass A1 reaction to fire, non-combustible to BS EN 13501-1.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e9.62m² per roll, and 230.98m² per pallet across 24 rolls.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGlass mineral wool designed for built-up metal roof and wall construction.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eECOSE® Technology binder, low dust and low volatile organic compound emissions in use.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHolds the Eurofins Gold Certificate for Indoor Air Comfort.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1200mm width to suit commonly used rail and bracket spacer systems.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eHigh tear strength for handling and for durability in service.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAbsorbs sound behind metal liner sheets, reducing internal reverberation.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMade with up to 80% recycled content, and rot proof and non-hygroscopic in service.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eGood to know:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\" class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3 print:block print:space-y-1\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCoverage per pallet drops as thickness rises:\u003c\/strong\u003e 24 rolls per pallet is constant, so a 140mm pallet delivers 230.98m² where an 80mm pallet delivers 406.08m².
