  • Minor handling marks from salvage and palletising; nothing affecting use.

Carbon & sustainability notes

The 103 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 608 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 Newcastle premises — telehandler on site, HGV access fine.
  • Seller can quote hiab or flatbed delivery within ~60 miles of Newcastle; from £95.
  • Ask the seller for close-up photos or a video walkround if you can't visit — they expect the request.

Typical applications

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 9 packs.
