I spotted this one at B&Q tonight at the Craigavon Warehouse in Northern Ireland, I can't find it online and not sure if it's available in smaller stores. There were no prices anywhere to be seen but when I asked it scanned at £5!
EDIT: Confirmed to be a fiver at most stores
The deal is for a pre-cut roll of mineral loft insulation for £5. These packs are unbranded in plain white plastic packaging and they had 2-3 pallets towards the font of the store.
Each roll is is pre cut to allow for different joist spacing and has measurements of 1100mm x 4900mm x 200mm (5.4SqM).
Admittedly, everyone now qualifies for a grant to have loft insulation fitted, but even with the grant the price is usually around £200 and not exactly quickly installed . I think many people could get themselves sorted a lot quicker and cheaper by making use of this deal, although you will need to install it yourself! At less than £1 per sq meter this is a cracking good deal for 200mm topup insulation and will pay for itself in months not years.
