Surplus stock like this exists because projects over-order to avoid downtime — the saving gets passed to you instead of the skip. As new surplus it is indistinguishable from merchant stock except for the price.
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.
If your project tracks embodied carbon (BREEAM, Part Z readiness, or client ESG reporting), keep this listing reference as evidence of avoided emissions.
Leaf sizes unless the listing says 'with frame'. Always measure your structural opening and allow for packers and tolerance before buying.
