End of line Job lotCondition grade 9/10 (End of line). Assessed by the seller at listing; figures below relate to this specific lot of 30 packs · ≈90m².
Acoustic mineral wool slabs. Packaging slightly creased, product immaculate. Ideal for studwall sound insulation. Located in Edinburgh — collection or arranged regional delivery available. Direct from Edinburgh Site Clearance Ltd, a demolition operating out of Edinburgh; live for 23 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. The range is discontinued: what is listed here is the entire available quantity.
This listing carries no CO₂-saved figure because the material is new; the sustainability win here is waste prevention — first-quality stock staying out of the waste stream entirely.
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.
The headline saving on this listing (waste avoidance) is benchmarked against producing virgin PIR/mineral wool boards (PIR ~3.5 kg CO₂e per m² at 100mm). That's the embodied-carbon figure — the emissions locked into new material at the point of manufacture, before it ever reaches your site.
In UK building terms, embodied carbon typically accounts for 40–60% of a project's whole-life emissions once operational energy is decarbonised. Reusing insulation like this lot from Edinburgh bypasses the manufacturing stage entirely, which is why substitution consistently outperforms offsetting on lifecycle assessments.
For projects tracking against Part Z (the proposed embodied-carbon amendment to the Building Regulations), BREEAM Mat 01 credits, or the RIBA 2030 Climate Challenge, reused material counts at zero embodied carbon in the A1–A3 modules. Keep the seller invoice, this listing URL and the CO₂e figure together in your carbon file.
Beyond carbon: buying this lot from Edinburgh Site Clearance Ltd keeps first-quality insulation out of the UK construction waste stream (currently ~62 million tonnes/year, per DEFRA). It supports the circular-economy supply chain — sellers who divert stock only continue diverting when there's a viable resale route.
No — what matters is the declared lambda value and installed thickness. Keep a facing photo showing the print line for your Building Regs file.
Flat, dry and off the ground. PIR facings degrade with prolonged UV exposure, so keep the wrap on until the day of fixing.
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.
Edinburgh Site Clearance Ltd issues a VAT invoice on collection or dispatch — bank transfer is standard, card on request. For anything over £500 we recommend a written spec confirmation before paying, so the exact insulation description and quantity are on record.
A short reservation (typically 48–72 hours) is usually possible with a 10% holding deposit. Surplus stock moves quickly, especially end of line lots at this price point — confirm the hold in writing so the seller doesn't re-list.
The material itself carries the same certifications as merchant stock; document the reuse route in your carbon log even without a specific CO₂e figure — waste avoidance still counts under Part Z reporting guidance.
