B&Q athlone/galway €24.95 per roll, 3 for 2, 200mm, the 170mm is cheaper at €21.95 again 3 for 2. When we started first we bought 10 roles in ganleys athlone for €300 so then heard B&Q doing deal.
The combi roll is the fibreglass stuff you roll out, bit itchy etc but ok if you cover up well.
The space blanket is the stuff inside a plastic/tinfoil cover so you dont actually touch the fibreglass. You place the tinfoil up towards the attic/roof. Was told it was better so just purchased it for the sitting room. I bought the really small rolls so extremely handy to carry/roll out etc.
I would double check everything in B&Q as different people tell you diff things, we drove to athlone one morning for few more rolls, out of stock, asked girl to ring galway to see if any, anyway told they were being discontinued and no point in her ringing, so husband rang galway from van and lady said 500 in stock, drove to galway, only 9 left of the 500 that originally came in, lucky our van crew cab so can only carry nine anyway.
