About this lot

Surplus from a hotel fit-out. Tapered edge for taping. 50% off merchant price. Located in Leeds — collection or arranged regional delivery available. Offered by Leeds Urban Reclamation (demolition) from their Leeds yard, listed 4 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. It is graded down on appearance alone; structurally and functionally it performs as A-grade.

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.

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 6 packs.
