About this lot

Surplus to a Passivhaus retrofit. Better λ than PIR. Sealed packs, dry stored. Located in London — collection or arranged regional delivery available. Listed 13 days ago by London Reclaim Co., a demolition based in London.

Every lot here was once destined for waste transfer — listing it instead keeps first-quality material in circulation at well below merchant list. As reclaimed stock it carries genuine history — the full condition report below states exactly what to expect.

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 240 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 1416 km of driving emissions, or 11 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 London premises — forklift loading available weekdays 7:30am–4pm.
  • Seller can quote hiab or flatbed delivery within ~60 miles of London; from £65.
  • Ask the seller for close-up photos or a video walkround if you can't visit — they expect the request.

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.
