made for internal wall and floor applications where sound absorption and noise reduction are needed. It is the most widely used acoustic insulation product in the UK for separating and internal wall and floor constructions, and the go-to choice for meeting Approved Document E of the Building Regulations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe 50mm roll is one of the most popular thicknesses in the range, offering a step up in acoustic performance from the 25mm version while still fitting comfortably within standard stud partitions.

Knauf's own literature describes the range as running to 300mm, and there is nothing above it.

A quilt laid in one pass gives one plane of insulation with joints only between adjacent rolls, all running the same way and all closing against each other. Once a build-up needs two laminated layers, there is a second set of joints to register, cross-joints to stagger deliberately so they do not line up, and more chance of a gap being left somewhere in the middle of the assembly where nobody will ever see it. Reaching 7.50 m²K\/W without any of that is the argument for taking the depth in one roll while the range still offers it.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eInstallation follows the same sequence as every thickness below it: liner sheet fixed, quilt laid over it, spacer system brought up to take it into the cavity, outer profiled sheet fixed last, to Knauf Insulation's guidance and the cladding system manufacturer's details. At 300mm the spacer system is bespoke rather than catalogue and should be agreed with the cladding system supplier at design stage. It is also worth being straight about the limits: at this depth the brackets penetrating the layer, not the wool, largely determine what the assembly achieves, so a modelled U-value calculation to BS EN ISO 10211:2017 is the only way to know what the depth is actually buying. Knauf's Technical Services Team will produce that calculation. The thickness suits envelopes carrying a demanding fabric target, including buildings served by low-temperature heating such as heat pumps, where the plant depends on low heat loss to run efficiently, and on farms it tends to appear on one-off builds specified above the regulatory minimum rather than to it.\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 7.50 m²K\/W, the highest in the FactoryClad range.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThe deepest FactoryClad roll Knauf make, across all three grades.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAchieves the depth in a single continuous layer, with no laminated cross-joints to stagger.\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\"\u003e3.84m² per roll, and 92.16m² per pallet across 24 rolls.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1200mm roll width to suit rail and bracket spacer systems.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eKnauf will produce a numerically modelled U-value calculation for the specific build-up.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMade with up to 80% recycled content and bound with ECOSE® Technology.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRot proof and non-hygroscopic, with a service life equivalent to that of the structure.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePerformance declared under G4207GPCPR against BS EN 13162:2012+A1:2015.\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\u003eThis is the deepest single layer available:\u003c\/strong\u003e anything beyond 7.50 m²K\/W from FactoryClad means laminating two layers, with the extra jointing and design that brings.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eThe brackets govern the result at this depth:\u003c\/strong\u003e ask for a modelled calculation to BS EN ISO 10211:2017 rather than a simplified figure, or the depth may not deliver what it looks like on paper.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBespoke spacer system:\u003c\/strong\u003e 300mm is well beyond catalogue bracket depths, so agree it with the cladding system supplier at design stage rather than at order stage.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLowest coverage in the range at 3.84m² per roll, so take off the area properly before ordering.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eAvailable in the 40 grade only, as Roll 35 stops at 220mm and Roll 32 at 80mm.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThe 40 denotes a declared conductivity of 0.040 W\/mK, not a thickness.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSupplied uncut at 3.20m per roll and unfaced on both faces.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eNon-hygroscopic, but not moisture resistant.

The mechanism is worth understanding rather than taking on trust. Sound absorption needs the wool to be reachable: air has to be able to move into the open fibre structure, which means an acoustically open liner, perforated or micro-perforated. Behind a solid steel liner, sound largely reflects off the sheet and the quilt cannot absorb much of it into the space, though the added mass and depth still reduce sound passing through the assembly from outside or from plant above. Both outcomes are useful, but they are different problems and the liner choice decides which one you are solving. Knauf do not publish sound absorption coefficients for FactoryClad Rolls, so any acoustic design should work from figures for the actual build-up, supplied by the cladding system manufacturer or established by test.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eInstallation is the standard build-up: liner sheet fixed, quilt laid over it, spacer system brought up to take it into the cavity, outer profiled sheet fixed last, to Knauf Insulation's guidance and the cladding system manufacturer's details.

The depth suits wide-span industrial and commercial buildings where noise is a live consideration alongside heat loss, and on farms it applies where a building sits close to a dwelling or carries a planning condition on noise, with grain driers, extraction fans or ventilation plant running into the evening.

At 240mm the roll runs 4.70m against the 220mm roll's 4.35m, so it covers 5.64m² where the 220mm covers 5.22m², and a pallet delivers 135.36m² against 125.28m².

The U-value of a built-up system depends on the material properties and on the degree of thermal bridging through it, and once the quilt is 240mm deep the wool is no longer the limiting factor: the spacer brackets penetrating the layer are. A simplified calculation may not capture that adequately. Knauf's own guidance is that U-values for a proprietary system should be produced using 2D or 3D modelling software compliant with BS EN ISO 6946:2017 or BS EN ISO 10211:2017, following BR443:2019, and they will carry out numerically modelled calculations where the detailing calls for it.

The depth suits industrial, commercial and agricultural buildings carrying a continuous heating or cooling load rather than seasonal use, and on farms that points to intensive livestock housing running heat through the year, such as farrowing houses and calf rearing units, and to refrigerated produce stores where the plant runs constantly and depth pays back against running cost.\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 6.00 m²K\/W at 240mm.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eLonger roll and greater coverage than the 220mm, at 4.70m and 5.64m² against 4.35m and 5.22m².\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\"\u003e135.36m² per pallet across 24 rolls.\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\"\u003eKnauf will produce numerically modelled U-value calculations for the specific build-up.\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\"\u003eRot proof and non-hygroscopic, and will not sustain vermin or support fungal or mould growth.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMade with up to 80% recycled content and bound with ECOSE® Technology.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePerformance declared under G4207GPCPR against BS EN 13162:2012+A1:2015.\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\u003eThe 240mm roll is longer than the 220mm:\u003c\/strong\u003e 4.70m against 4.35m.

FactoryClad is a cladding quilt, supplied uncut at 1200mm wide to suit the rail and bracket spacer systems used in twin-skin profiled metal cladding and standing seam roofs.

A cavity this deep carries a large temperature difference across it in winter, and where the dew point falls within the build-up becomes a design question rather than a product one. Because the quilt is close to vapour open, moisture control in a built-up system rests on the vapour control layer, the sealing of the liner sheet and the detailing, not on the insulation resisting vapour. Specify and seal that layer properly and the depth works for you. Leave it to chance and the depth simply relocates the dew point somewhere less convenient.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe build-up runs liner sheet, quilt, spacer system, outer sheet, to Knauf Insulation's guidance and the cladding system manufacturer's details. Knauf size the roll at 1200mm specifically for the rail and bracket systems used in twin-skin profiled cladding and standing seam roofs, so on a standing seam job the width should drop onto the existing clip and rail spacings without fuss. 200mm suits wide-span industrial and commercial buildings that are heated or cooled and occupied through the year, where the roof is the dominant heat loss path, and on farms that takes in packhouses, grading rooms and on-farm processing units. One point in its favour in those settings is that the quilt is fully enclosed by the liner sheet, so it is not present in the occupied space at all.

On new agricultural units this depth tends to appear where the building works as plant rather than shelter, in potato and onion stores, controlled-atmosphere stores and grain buildings running drying equipment, where the envelope is designed alongside the kit inside it.\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 4.50 m²K\/W at 180mm.\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\"\u003e7.51m² per roll, and 180.29m² per pallet across 24 rolls.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eNo blowing agent in the product, so it works to its declared conductivity.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eService life equivalent to that of the structure it is built into, as stated by Knauf.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eOdourless, rot proof and non-hygroscopic, and will not sustain vermin or support fungal, mould or bacterial growth.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCovered by Declaration of Performance G4207GPCPR.\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\u003eClosed in for the life of the cladding:\u003c\/strong\u003e the quilt is not accessible once the outer sheet is fixed, so get the depth and the spacer system right before the skin goes on.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eEuroclass A1 is a reaction to fire classification, not a fire resistance period:\u003c\/strong\u003e it describes how the material itself behaves in a fire.

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.

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.

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.

Rolls of glass mineral wool knit into one another and take up slight irregularities in the liner sheet instead of bridging them, and they hold that contact as the frame settles and moves. Rigid insulation cannot do this: it either fits or it leaves a void, and voids are where a designed U-value quietly disappears. At 120mm the quilt is also compressed and released as it passes each bracket, and recovering afterwards is part of what keeps the layer continuous.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eInstallation runs in the usual sequence: liner sheet fixed, quilt laid over it, spacer system brought up, outer sheet fixed, all to Knauf Insulation's guidance and the cladding system manufacturer's details.

It suits new-build twin-skin roofs and walls, standing seam roofs, and re-cladding work where the target U-value has moved on from whatever the original build-up could reach. Have the U-value calculated for the actual system to BS EN ISO 6946:2017 or BS EN ISO 10211:2017, using BR443:2019, rather than working back from the roll.\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 3.00 m²K\/W at 120mm.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThe only 120mm option across the FactoryClad Roll 32, 35 and 40 grades.\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\"\u003eNon-combustible, Euroclass A1 to BS EN 13501-1.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e11.28m² per roll, and 270.72m² per pallet across 24 rolls.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eKnits at the joints and takes up substrate irregularities, limiting air gaps through the layer.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSound absorbent behind metal liner sheets, reducing internal reverberation.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e1200mm width matched to commonly used rail and bracket spacer systems.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003ePublished embodied carbon of 1.04 kgCO2e\/m² across stages A1 to A3.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eBound with ECOSE® Technology, free of added formaldehyde and phenol.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eRot proof and non-hygroscopic, and will not sustain vermin or support 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\u003eOnly made in the 40 grade:\u003c\/strong\u003e FactoryClad Roll 32 comes in 80mm and Roll 35 runs 60, 100, 140, 180 and 220mm, so 120mm is available from Roll 40 alone.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCheck the spacer system before ordering:\u003c\/strong\u003e bracket height and fixing lengths need to suit 120mm, not the depth the building was originally clad to.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBuilt-up metal construction only:\u003c\/strong\u003e this is not a loft, timber frame or masonry cavity product.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eThe 40 in the name is a lambda grade referring to 0.040 W\/mK, not a thickness.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eSupplied uncut at 9.40m per roll and unfaced on both sides.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eKeep it dry, flat, off the ground and under cover, and re-cover any pack that has been opened.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEuroclass A1 non-combustibility may bear on the insurance position against foam composite panels.
