Condition report & known defects

8/10
  • Sold as carefully de-nailed strip-out stock — verify facings before airtightness-critical use.
  • Minor handling marks from salvage and palletising; nothing affecting use.

Carbon & sustainability notes

Choosing this lot over new product avoids an estimated 244 kg CO₂e — benchmarked against producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm).

For scale: roughly 1440 km in a typical petrol car, or a year's absorption for 12 established trees.

With Part Z and embodied-carbon reporting moving up the agenda, documented reuse like this is increasingly worth recording in your project's carbon log.

Collection & delivery

  • Collection from the seller's Bristol premises — forklift loading available weekdays 7:30am–4pm.
  • Nationwide pallet courier available — typically £45–£85 per pallet, 2–4 working days.
  • Viewings welcomed by appointment; the measurements table above reflects what was checked at listing.

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.
