Contact sellerHow buying works

Condition grade 6/10 (B-grade). Assessed by the seller at listing; figures below relate to this specific lot of 60 boards.

About this lot

Brand new, banded. Suits floors, walls and warm roof construction. Located in Leeds — collection or arranged regional delivery available. Direct from Leeds Urban Reclamation, a demolition operating out of Leeds; live for 12 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. It is graded down on appearance alone; structurally and functionally it performs as A-grade.

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 4 packs.
