Hi,
I have a small area which I need to insulate in the loft which is to hard to access to fit glass wool or rigid insulation. I am considering using Warmcel which I can put in place by hand (have long arms). Warmcel is available in bags but the info on the bag does not indicate the coverage. No information at web site either. The stuff in the bag appears to be compressed and I am assuming it expands (a bit like moss peat perhaps) but I was wondering if anyone had used bagged Warmcel and could give an idea of how much it covers (225mm joist depth in my case).
Thanks
