About this lot

MR plasterboard for bathrooms and kitchens. Green-faced, 15mm thick. Sealed, dry stored. Fresh to market — posted 3 days ago by Leeds contractor Yorkshire Plasterers.

Surplus stock like this exists because projects over-order to avoid downtime — the saving gets passed to you instead of the skip. As new surplus it is indistinguishable from merchant stock except for the price.

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.

Reuse is the single fastest way to cut a build's embodied carbon — substitution beats offsetting every time.

Collection & delivery

  • Collection from the seller's Leeds premises — forklift loading available weekdays 7:30am–4pm.
  • Regional pallet delivery can be arranged from £55 depending on postcode and lead time.
  • Inspection before purchase is encouraged — bring a tape and check sample units against the measurements above.

Typical applications

  • Floor insulation under screed or chipboard
  • Dot-and-dab and stud-wall drylining
  • Garage conversions and garden offices
  • Acoustic upgrades between floors

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 5 packs.
