About this lot

Surplus to a Passivhaus retrofit. Better λ than PIR. Sealed packs, dry stored. Located in Glasgow — collection or arranged regional delivery available. Listed 18 days ago by Glasgow Greenfield Contractors, a contractor based in Glasgow.

Every lot here was once destined for waste transfer — listing it instead keeps first-quality material in circulation at well below merchant list. As new surplus it is indistinguishable from merchant stock except for the price.

Condition report & known defects

10/10
  • Stored under cover since delivery; no weather exposure.
  • Unused stock — original banding/packaging intact where stated.
  • Original wrap opened on one pack for count verification, re-taped.
  • Corner crush on ~12% of boards from transit — cut-around loss only.

Carbon & sustainability notes

Reusing this material saves roughly 77 kg CO₂e versus producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm).

That's equivalent to about 454 km of average petrol-car driving, or what 4 mature trees absorb in a year.

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 Glasgow premises — pallet truck on site; tail-lift vehicles recommended.
  • Regional pallet delivery can be arranged from £40 depending on postcode and lead time.
  • Inspection before purchase is encouraged — bring a tape and check sample units against the measurements above.

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 3 packs.
