About this lot

For bathrooms and kitchens. Green-faced, sealed, dry stored. Located in Sheffield — collection or arranged regional delivery available. Offered by Sheffield Greenfield Contractors (contractor) from their Sheffield yard, listed 2 days ago.

Site over-orders, cancelled jobs and careful strip-outs are where the best material bargains in the UK come from — this lot is one of them. This is unused, current-spec material — the only thing second-hand about it is the price tag logic.

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 2 packs.
