Modern fibreglass loft insulation stands proud of the rafters by a couple of inches or so. This means that if boarding out the loft for storage etc. the f/g insulation inevitably gets compressed, and I assume becomes less effective. Is there a way round this, or doesn't it matter that much? Is there any insulation board that is more efficient than f/g roll, thus providing the same degree of insulation but with less thickness, that could be laid between the joists under the boarding (e.g. Kingspan or similar)?
