Built-up metal walls are framed on side rails rather than purlins, with the quilt held off the liner sheet by a bracket and rail spacer system before the outer profiled sheet is fixed. At 160mm that spacer system needs specifying for the depth rather than being asked to accommodate it after the fact.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eEach roll measures 7.05m by 1200mm and covers 8.46m², with 24 rolls to a pallet giving 203.04m². Declared thermal conductivity is 0.040 W\/mK, producing a thermal resistance of exactly 4.00 m²K\/W, and water vapour resistivity is 5.00 MNs\/g.m. Published embodied carbon is 1.38 kgCO2e\/m² across stages A1 to A3 and 1.83 kgCO2e\/m² across A1 to C4. For a quantity, divide the net area of the roof slope or elevation by 8.46 for rolls, then allow for cutting and waste at ends and details.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThere is a reason a 160mm roll still fits 24 to a pallet. Knauf use a three-tier compression packaging process that loads more product into each pack and pallet, so a deep quilt arrives in much the same footprint as a slim one. That means less packaging per square metre, fewer vehicles for the same delivered area, and less space tied up on site while the job runs. The wool itself is made with up to 80% recycled content, including glass recovered from windows, bottles and jars, and Knauf hold a BES 6001 (v4.0) 'Very Good' rating for responsible sourcing across their mineral wool plants.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe build-up sequence is the same on a wall as on a roof: liner sheet fixed, quilt laid over it, spacer system brought up to take the quilt into the cavity, outer sheet fixed last, all in line with Knauf Insulation's guidance and the cladding system manufacturer's details. It suits new-build twin-skin walls and roofs, standing seam roofs, and re-cladding where the thermal target has moved on from the original build-up. On farms, 160mm often goes into buildings that have changed use, where a shed has become a workshop, a storage unit or a light industrial let and is now heated and occupied all day. Whichever the case, the U-value belongs to the whole assembly, so have it calculated to BS EN ISO 6946:2017 or BS EN ISO 10211:2017 using BR443:2019.\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 exactly 4.00 m²K\/W at 160mm.\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\"\u003e8.46m² per roll, and 203.04m² per pallet across 24 rolls.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSuits built-up metal walls on side rails as readily as built-up metal roofs.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCompression packaged, so a deep roll ships in much the same pallet footprint as a slim one.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMade with up to 80% recycled content, including recovered window and container glass.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBES 6001 (v4.0) 'Very Good' rating for responsible sourcing.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1200mm roll 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\"\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\"\u003eBound with ECOSE® Technology, with no added formaldehyde or phenol.\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\u003e160mm in the 40 grade matches 140mm in the 35 grade:\u003c\/strong\u003e both reach 4.00 m²K\/W.
