About this lot

Brand new, banded. Suits floors, walls and warm roof construction. Located in Sheffield — collection or arranged regional delivery available. Offered by Sheffield Greenfield Contractors (contractor) from their Sheffield yard, listed 18 days ago.

Site over-orders, cancelled jobs and careful strip-outs are where the best material bargains in the UK come from — this lot is one of them. This is unused, current-spec material — the only thing second-hand about it is the price tag logic.

Carbon & sustainability notes

The 46 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 271 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.

  • Seller can quote hiab or flatbed delivery within ~30 miles of Sheffield; from £90.

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.
