About this lot

Brand new, banded. Suits floors, walls and warm roof construction. Located in Manchester — collection or arranged regional delivery available. Listed 10 days ago by Manchester Greenfield Contractors, a contractor based in Manchester.

Every lot here was once destined for waste transfer — listing it instead keeps first-quality material in circulation at well below merchant list. As new surplus it is indistinguishable from merchant stock except for the price.

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.

Collection & delivery

  • Collection from the seller's Manchester premises — car/van accessible, assistance with loading provided.
  • Seller can quote hiab or flatbed delivery within ~60 miles of Manchester; from £40.
  • Ask the seller for close-up photos or a video walkround if you can't visit — they expect the request.

Typical applications

  • Acoustic upgrades between floors
  • Warm roof build-ups and rafter-level insulation
  • Floor insulation under screed or chipboard
  • Dot-and-dab and stud-wall drylining

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.
