Condition grade 10/10 (New surplus). Assessed by the seller at listing; figures below relate to this specific lot of 24 m².

About this lot

Sealed bales of British sheep's wool. Breathable, low embodied carbon, no itch. Located in Manchester — collection or arranged regional delivery available. Listed 6 days ago by Manchester Greenfield Contractors, a contractor based in Manchester.

Every lot here was once destined for waste transfer — listing it instead keeps first-quality material in circulation at well below merchant list. As new surplus it is indistinguishable from merchant stock except for the price.

Carbon & sustainability notes

Choosing this lot over new product avoids an estimated 33 kg CO₂e — benchmarked against producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm).

For scale: roughly 195 km in a typical petrol car, or a year's absorption for 2 established trees.

With Part Z and embodied-carbon reporting moving up the agenda, documented reuse like this is increasingly worth recording in your project's carbon log.

Collection & delivery

  • Collection from the seller's Manchester premises — forklift loading available weekdays 7:30am–4pm.
  • Nationwide pallet courier available — typically £40–£95 per pallet, 2–4 working days.
  • Viewings welcomed by appointment; the measurements table above reflects what was checked at listing.

Typical applications

  • Floor insulation under screed or chipboard
  • Dot-and-dab and stud-wall drylining
  • Garage conversions and garden offices
  • Acoustic upgrades between floors

Questions about this lot

Do part-sheets affect building control sign-off?+

No — what matters is the declared lambda value and installed thickness. Keep a facing photo showing the print line for your Building Regs file.

How should boards be stored on site?+

Flat, dry and off the ground. PIR facings degrade with prolonged UV exposure, so keep the wrap on until the day of fixing.

Is mixed-brand insulation OK in one roof?+

Yes, provided each zone's U-value calc uses the correct lambda for the board actually installed there. This lot is single-brand across all 7 packs.
