loft insulation offer
Martin Davies
£8 for 4 rolls of loft insulation at Focus DIY
In stores only
Grab four rolls of Knauf loft insulation for the price of one in Focus DIY stores until Mon 31 Jan.
The offer's on Knauf Space Combi (£23.99 for 100mm or 170mm) and Space Blanket (£11.99 for 170mm or 200mm).
Plus get £4 off your purchase when you fill in a special voucher meaning you can grab four rolls for £8. The voucher is one per household. (If you can't print this off you can pick one up in stores).
The offer's in store only in Focus branches nationwide. Find your nearest Focus. Do note the rolls can be large, so you may need to think about taking a van or a large car.
How many rolls do you need?
If you're not sure how many rolls you'll need there's a nifty online calculator on the B&Q website which will tell you based on the square foot area of your loft.
The offer's limited to 100m2 per household meaning you can buy 7 rolls of the 100mm Space Combi, 12 of the 170mm Space Combi, 60 of the 150mm Space Blanket and 67 of the 200mm Space Blanket.
According to the Energy Saving Trust 270mm is the recommended depth for wool insulation to get the maximum amount of heat insulation, though other materials differ. More info at the Energy Saving Trust.
Free loft insulation?
Anyone aged over 70, plus others in receipt of certain benefits, can get grants to help pay loft insulation costs, or even get it for free. Full details in the Energy Grants Guide.
