Easy to install in standard 420 centres. Just need overalls, nylon tape and a good staple gun.

Easy to install, fits snuggly between my joists. Only just installed so can't comment on too much on insulating properties but seems to be keeping airflow and definitely keeping dust from circulating from up into the house, would recommend. Wear as much protective wear as possible due to the thin glass fibre protective layer.
