Sold by Glasgow Greenfield Contractors (Contractor) · Ref L0471

Condition grade 9/10 (New surplus). Assessed by the seller at listing; figures below relate to this specific lot of 60 boards.

About this lot

Brand new, banded. Suits floors, walls and warm roof construction. Located in Glasgow — collection or arranged regional delivery available. Direct from Glasgow Greenfield Contractors, a contractor operating out of Glasgow; live for 14 days.

This is exactly the kind of material that typically ends up in a skip costing the seller money; buying it diverts it back into a build. This is unused, current-spec material — the only thing second-hand about it is the price tag logic.

Condition report & known defects

Carbon & sustainability notes

Choosing this lot over new product avoids an estimated 46 kg CO₂e — benchmarked against producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm).

For scale: roughly 271 km in a typical petrol car, or a year's absorption for 2 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 Glasgow; telehandler on site, HGV access fine.
  • Nationwide pallet courier available — typically £35–£60 per pallet, 2–4 working days.
  • Viewings welcomed by appointment; the measurements table above reflects what was checked at listing.

Typical applications

  • Garage conversions and garden offices
  • Acoustic upgrades between floors
  • Warm roof build-ups and rafter-level insulation
  • Floor insulation under screed or chipboard

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 8 packs.
