Among other house-hacking projects, insulating and flooring the attic are currently in progress. This will become a home for my server, and the noisy parts of my computer kit (and will also leave us a little more space in the rest of the house !)
We looked at the options for insulating it, we peeked up after a few weeks in the house, and realised no-one had been up there since the place was re-wired in the 1970s. The insulation was ancient, and might as well not have been there. So, we decided to insulate on the slopes of the roof – to ensure the temp in the attic was reasonable all year-round.
Sheep wool insulation (www.sheepwoolinsulation.ie) seemed an obvious choice. It’s as good as, if not better than fibreglass, and doesn’t need all the protective gear. The guys in Rathdrum are really nice too – happy to talk (even though they’re overworked at the moment) and great to deal with, they even called me the day after the insulation was delivered to check that it had arrived okay !
So far the experience of installing it hasn’t been too bad – hardest part is the climbing around the attic … maybe we should have put the floor down first !!
