Used to insulate walls in a garage. Made a difference on temperature instantly. Easy to pull apart for sizing. Light and easy to move. Has little itchy bits, but they all do. Easy clean up. Very happy with it.

Good quality product & does the job

Check your roof access hole size as I only just managed to squeeze these in but it was a fair bit of effort. Otherwise you might need to take off tiles.It was easy to lay & only a little bit itchy.Insulation seems to work as house feels better temperature wise.
