Insulation

Sagging insulation between rafters in loft

Anonymous user 09/03/2024 - 3.25 PM

We have a 3 storey house completed in 2005 that has a bedroom on the top floor with a small loft space above. The whole roof space has been insulated between the rafters with rockwool type insulation but in the loft, which is already a small space, the insulation is sagging as it's only supported by a few battens making the space even smaller/uncomfortable to access. Without wanting to restrict airflow, what would be the best way to hold the insulation back in the loft so that I don't end up brushing along insulation when I go up into the loft? I was considering something like Thermawrap as it should hold it back, can be attached to the rafters and has some thermal properties but I don't know if it would cause more harm than good?
