About this lot

Sealed bales of British sheep's wool. Breathable, low embodied carbon, no itch. Located in Bristol — collection or arranged regional delivery available. Listed 9 days ago by Bristol Reclaim Co., a demolition based in Bristol.

Condition report & known defects

8/10
  • Minor handling marks from salvage and palletising; nothing affecting use.
  • Sold as carefully de-nailed strip-out stock — verify facings before airtightness-critical use.

Carbon & sustainability notes

The 99 kg CO₂e figure on this listing is calculated against producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm).

Put another way — about 584 km of driving emissions, or 5 tree-years of carbon uptake.

If your project tracks embodied carbon (BREEAM, Part Z readiness, or client ESG reporting), keep this listing reference as evidence of avoided emissions.

Collection & delivery

  • Collection from the seller's Bristol premises — kerbside hand-load or forklift by arrangement.
  • Seller can quote hiab or flatbed delivery within ~60 miles of Bristol; from £50.
  • Ask the seller for close-up photos or a video walkround if you can't visit — they expect the request.

Typical applications

  • Dot-and-dab and stud-wall drylining
  • Garage conversions and garden offices
  • Acoustic upgrades between floors
  • Warm roof build-ups and rafter-level insulation

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.
