In response to the Homebase offer of £11.48 buy one get three free B&Q have reduced their pricing so it works out at £2.78 per roll.
( Just trying to work out how to do nice url link instead of stuff below)
NOTE. I personally would go to B&Q and before purchasing at the price of £5.56 for two I would print the Homebase price ( http://www.homebase.co.uk/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=20001&partNumber=481240&Trail=searchtext>SPACE+BLANKET)
and 15% ( http://www.hotukdeals.com/all/vouchers/new?expired=false&mf=222
) voucher which means Homebase price is £2.44 per roll and ask for a pricematch which will give you a further 10% discount. Space Blanket is small rolls so should fit through any loft hatch.
The other option is to use N Power deal for 2 for 1 Rockwool insulation which can be picked up or delivered free by Build Center. This works out as a slightly better deal.
descriptionBuy One Get One Free. Reserve one, get two when you collect in store. Space Blanket is encapsulated glass mineral wool loft insulation. Virtually "itch free", it will form a barrier preventing heat loss, and so reduce the cost of heating/cooling your home.
