Condition report & known defects

7/10
  • Expect natural variation in tone and texture across the batch — this is the appeal of reclaimed stock.
  • Surface weathering consistent with age — structurally sound throughout.

Carbon & sustainability notes

The 40 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 236 km of driving emissions, or 2 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

  • Buyer collection in London; telehandler on site, HGV access fine.
  • Seller can quote hiab or flatbed delivery within ~30 miles of London; from £75.
  • Ask the seller for close-up photos or a video walkround if you can't visit — they expect the request.

Typical applications

  • Garage conversions and garden offices
  • Acoustic upgrades between floors
  • Warm roof build-ups and rafter-level insulation
  • Floor insulation under screed or chipboard

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 6 packs.
