(I used the B&Q one when I did my bathrooms a couple of years back -
there was an area of ceiling void that was uninsulated, so I picked up a
couple of rolls of the Eko roll. It was definitely noticeable that it
was much much nicer to handle than normal glass wool)

I laid a few rolls of this (the 170mm thick variety which comes with partially cut
widths for 400 or 600mm joist spacing) recently wearing gloves and a facemask
but with bare arms which occasionally came into contact with it. I was pleasantly
surprised not to have any itching afterwards. There was very little airborne dust.

Interesting. It seems they still recommend gloves but it's less scratchy.
Perhaps I should grab some rolls from Wickes and give it a test...

It appears their contractors' version (Earthwool Loft Roll 44) is made of
the same stuff and that's readily available.


In other news, what would the team recommend for insulating the rear of
vertical stud partitions? There's already fibreglass insulation, but the
back of the studs is exposed? If I were to pin some Celotex to it I'd
compress the wool in there. I don't think rockwool is good for vertical
surfaces, especially not strung horizontally?
