I wish to install loft insulation to the equivalent of 270 mm glass fibre blanket. I also want to put down flooring in the loft.
However, my joists are only 100 mm deep so I cannot put down a floor and glass fibre blanket to a depth of 270mm.
Is there an alternative insulation material which is no more than 100 mm thick and could give me the required level of insulation ?
