Questions & Answers


can this be used as an under roof insulation layer, sealed in with a layer of plywood?


This is designed to be used at the base of the loft, rolled out between the joists at the flooring level, due to its composition you won't be able to fix it at the roof rafter level. 


Isover Spacesaver Loft Roll Insulation Glass Wool 200mm - 6.03m2 Roll Hi I’m looking to add this product as a second layer laid over the joist. So I’m just looking to work out square meterage. If laid at 1160mm wide I’m calculating they are 5.2m long = 6.03M2 Can you confirm please.
