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.
