It sits in the cavity formed between the inner liner sheet and the outer profiled weather sheet, carried on the rail and bracket spacer system, and is the entry thickness in the FactoryClad Roll 40 range. Twin-skin cladding on steel-framed industrial, commercial and agricultural buildings is its primary use.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eEach roll runs 14.10m long by 1200mm wide, covering 16.92m², with 24 rolls to a pallet for 406.08m² in a single drop. Thermal conductivity is declared at 0.040 W\/mK, giving a thermal resistance of 2.00 m²K\/W at 80mm, and vapour resistivity is 5.00 MNs\/g.m. At this depth the roll carries the largest coverage of any thickness in the grade, which is what makes it the usual pick where the existing spacer system fixes the cavity depth and a full re-specification is not on the table.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eHigh tear strength counts for most on the longest roll in the range. Unrolling 14.10m across purlins or side rails, at height and often in wind, puts more handling stress on the quilt than a three-metre roll ever will, and a quilt that resists tearing goes in whole rather than in patched sections. Torn edges and gaps are where a built-up system loses the performance it was calculated for.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eFactoryClad Roll 40 is laid over the liner sheet and taken up into the cavity by the spacer system before the outer sheet is fixed, in line with Knauf Insulation's guidance and the cladding system manufacturer's details. Because it is glass mineral wool it knits to slight irregularities in the substrate rather than bridging them, keeping contact across the run as the building moves and settles. On agricultural buildings the same 80mm layer does a second job: warming the underside of the sheet lifts it clear of dew point and cuts the surface condensation that drips onto stock, feed and machinery. U-values are a property of the whole build-up rather than the quilt on its own, so have the figure calculated for the specific system before ordering.\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\"\u003e80mm glass mineral wool roll for built-up metal roof and wall systems.\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\"\u003eThermal resistance of 2.00 m²K\/W at 80mm.\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\"\u003e16.92m² per roll, the largest coverage in the FactoryClad Roll 40 grade.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e24 rolls per pallet, giving 406.08m² per pallet for larger runs.\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\"\u003eHigh tear strength for handling long runs at height.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGlass mineral wool absorbs sound and reduces reverberation inside metal-lined roofs and walls.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eManufactured with ECOSE® Technology, a plant-based binder with no added formaldehyde or phenol.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRot proof, non-hygroscopic, and will not sustain vermin or support fungal or mould growth.\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\u003eBuilt-up systems only:\u003c\/strong\u003e designed for twin-skin profiled metal roofs and walls, not for loft, timber frame or cavity masonry work.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eThe 40 is a lambda grade, not a thickness:\u003c\/strong\u003e FactoryClad Rolls are made in 32, 35 and 40 grades, referring to declared thermal conductivities of 0.032, 0.035 and 0.040 W\/mK.
