About this lot

Mixed PIR pieces, all usable. Perfect for stud walls and ceiling bays. Thermally identical to full boards. Located in Birmingham — collection or arranged regional delivery available. Listed 27 days ago by Birmingham Site Clearance Ltd, a demolition based in Birmingham.

Every lot here was once destined for waste transfer — listing it instead keeps first-quality material in circulation at well below merchant list. End-of-line means first quality with no re-order — quantity certainty matters more than usual, so check coverage twice.

Condition report & known defects

10/10
  • No re-order possible: buy the full quantity you need from this lot.
  • Manufacturer rebrand stock — identical product, superseded packaging print.

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 Birmingham premises — kerbside hand-load or forklift by arrangement.
  • 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

  • Dot-and-dab and stud-wall drylining
  • Garage conversions and garden offices
  • Acoustic upgrades between floors
  • Warm roof build-ups and rafter-level insulation

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 7 packs.
