Product Description
Product Description
220mm Knauf FactoryClad Roll 40 is a glass mineral wool insulation roll for built-up metal roof and wall systems, at a depth that generally appears on larger projects where the specification is documented and checked rather than settled informally. That changes what matters about a product. Alongside the thermal figures, the question becomes what evidence comes with it, and this range carries a fuller set than most cladding quilts.
Each roll measures 4.35m by 1200mm and covers 5.22m², with 24 rolls to a pallet giving 125.28m². Declared thermal conductivity is 0.040 W/mK, giving a thermal resistance of 5.50 m²K/W, and water vapour resistivity is 5.00 MNs/g.m. Published embodied carbon is 1.90 kgCO2e/m² across stages A1 to A3 and 2.52 kgCO2e/m² across A1 to C4.
The paperwork is worth understanding rather than skimming. Performance is declared under G4207GPCPR against BS EN 13162:2012+A1:2015. The fibre itself is certified by EUCEB, the mineral wool industry's independent certification board, which confirms it is made from non-classified fibres meeting the exoneration criteria for carcinogenicity under Note Q of Regulation (EC) 1272/2008. Knauf also hold the Declare 'Red List Free' label on all their glass mineral wool, which is third-party ingredient disclosure: it works like a nutrition label for a building product, setting out where the material comes from and what it is made of, and certifying that none of the Red List chemicals are present. On top of that sit a published Environmental Product Declaration, a BES 6001 (v4.0) 'Very Good' responsible sourcing rating across all three UK plants, and a BREEAM helpsheet for the glass wool. For anyone completing a materials schedule or answering a client's environmental questions, that is a complete trail rather than a partial one.
Installation is the familiar sequence: 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. Confirm the bracket height and fixing lengths will carry 220mm before ordering. The depth suits large-span industrial, commercial and agricultural buildings where the thermal target is set by a designer rather than by habit, and it appears on new agricultural work of real scale, in large dairy and bulk handling buildings put up as part of a wider capital scheme. As always the U-value belongs to the assembly and should be calculated to BS EN ISO 6946:2017 or BS EN ISO 10211:2017 using BR443:2019.
Key Benefits of Knauf FactoryClad Roll 40:
- Thermal resistance of 5.50 m²K/W at 220mm.
- Declared thermal conductivity of 0.040 W/mK.
- Euroclass A1 reaction to fire, non-combustible to BS EN 13501-1.
- 5.22m² per roll, and 125.28m² per pallet across 24 rolls.
- Performance declared under G4207GPCPR against BS EN 13162:2012+A1:2015.
- EUCEB certified, made from non-classified fibres.
- Declare 'Red List Free' label, giving third-party ingredient disclosure.
- BES 6001 (v4.0) 'Very Good' responsible sourcing rating across all three UK plants.
- Published Environmental Product Declaration and a BREEAM helpsheet for the glass wool.
- 1200mm roll width to suit commonly used rail and bracket spacer systems.
- Bound with ECOSE® Technology, with no added formaldehyde or phenol.
Good to know:
- The evidence set is worth collecting up front: DoP, EPD, Declare label, EUCEB certification and the BREEAM helpsheet are all published, and gathering them before submission is quicker than chasing them afterwards.
- Check the spacer system carries 220mm: at this depth bracket height and fixing lengths need confirming rather than assuming, on walls as well as roofs.
- A1 describes the material, not the assembly: any fire resistance period for the roof or wall belongs to the tested build-up and to the building's fire strategy.
- The 40 refers to a declared conductivity of 0.040 W/mK, not a thickness.
- Supplied uncut at 4.35m per roll and unfaced on both faces.
- Non-hygroscopic, but not moisture resistant. Keep it dry and covered, and discard any roll that has taken water.
- Avoid crushing the roll edges in handling and storage, and discard damaged product rather than installing it.
At 220mm the figures do the thermal work and the documentation does the rest, which is exactly what a specified project needs from a cladding quilt.

Thermal performance helps show how effectively the product reduces heat transfer.
Thermal conductivity measures how readily heat passes through the material, so lower figures generally indicate better insulating performance.
R Value shows the material’s thermal resistance at that thickness, so higher figures generally mean stronger insulation performance.
These figures relate to the insulation product itself and should be considered alongside the full wall, roof or floor build-up when checking project requirements.
- Thermal Conductivity:
- 0.40 W/mK
Euroclass reaction to fire is the European EN 13501-1 classification used to show how a construction product behaves when exposed to fire.
The main scale runs from A1 and A2 at the highest end, through B, C, D and E, down to F.
A1 is non-combustible and A2 is limited combustibility, while lower classes indicate a greater contribution to fire.
Euroclass F is the lowest rating on this scale and indicates the weakest reaction-to-fire performance.
This is different from fire resistance, which relates to how long a complete wall, floor or roof build-up can resist fire.
- Reaction to Fire:
- Euroclass A1
