Condition report & known defects

7/10
  • Expect natural variation in tone and texture across the batch — this is the appeal of reclaimed stock.
  • Surface weathering consistent with age — structurally sound throughout.

Carbon & sustainability notes

Choosing this lot over new product avoids an estimated 174 kg CO₂e — benchmarked against producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm).

For scale: roughly 1027 km in a typical petrol car, or a year's absorption for 8 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

  • Buyer collection in Bristol; pallet truck on site; tail-lift vehicles recommended.
  • Nationwide pallet courier available — typically £90–£115 per pallet, 2–4 working days.
  • Viewings welcomed by appointment; the measurements table above reflects what was checked at listing.

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 6 packs.
