Carbon & sustainability notes

No reuse CO₂ credit is claimed on this lot: it is unused stock, so the embodied carbon was committed at manufacture. Buying it still prevents waste — material sent to landfill or energy recovery delivers none of its embodied value.

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 Sheffield premises — pallet truck on site; tail-lift vehicles recommended.
  • Seller can quote hiab or flatbed delivery within ~60 miles of Sheffield; from £85.
  • Ask the seller for close-up photos or a video walkround if you can't visit — they expect the request.

Typical applications

  • Warm roof build-ups and rafter-level insulation
  • Floor insulation under screed or chipboard
  • Dot-and-dab and stud-wall drylining
  • Garage conversions and garden offices

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.
