Contact sellerHow buying works

Condition grade 9/10 (New surplus). Assessed by the seller at listing; figures below relate to this specific lot of 4-pane bi-fold.

About this lot

Surplus to a luxury extension. Slim sightlines, thermally broken. Sealed and stored in workshop. Located in Sheffield — collection or arranged regional delivery available. Direct from Sheffield Greenfield Contractors, a contractor operating out of Sheffield; live for 10 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.

Carbon & sustainability notes

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.

  • Nationwide pallet courier available — typically £35–£75 per pallet, 2–4 working days.
  • Viewings welcomed by appointment; the measurements table above reflects what was checked at listing.

Typical applications

  • Self-build glazing packages at a discount
  • Feature stained-glass and fanlight restoration
  • Workshop, garage and outbuilding upgrades
  • Period renovation and like-for-like replacements

Questions about this lot

Are the stated sizes the door leaf or the frame?+

Leaf sizes unless the listing says 'with frame'. Always measure your structural opening and allow for packers and tolerance before buying.

Can old doors be trimmed to fit?+

Solid timber doors trim comfortably by up to 11mm per edge. Engineered and fire doors have strict trim limits — check the certification label first.

Is the glazing safety glass?+

Modern units from Sheffield Greenfield Contractors are toughened where regulations require. Original period glass is not safety glass — re-glaze below 800mm or in door zones.
