Mr Punter Posted December 12, 2018 Share Posted December 12, 2018 Makes me itch just thinking about it! Link to comment Share on other sites More sharing options...
Jeremy Harris Posted December 12, 2018 Share Posted December 12, 2018 It was one of the worst jobs in the build, stuffing that into the ceiling void. I wore a Tyvek suit, with the hood up and a mask on, plus I taped around the glove/sleeve joint and around my ankles, but the damned stuff still got in...

vivienz Posted December 12, 2018 Author Share Posted December 12, 2018 I can't say I'm looking forward to it, but has to be done. I may wear my beekeeping suit! Link to comment Share on other sites More sharing options...
Gone West Posted December 12, 2018 Share Posted December 12, 2018 I used Rockwool RWA6 which are batts or slabs, as EWI on my build. I assume RWA45 are also batts which are resin bonded, fairly rigid and easy to cut and work with. Link to comment Share on other sites More sharing options...
Big Neil Posted December 12, 2018 Share Posted December 12, 2018 obviously i'm the thick cousin on this forum, but i didn't think rockwool was itchy. I thought it was only fibreglass insulation that made people itch???? Link to comment Share on other sites More sharing options...

Big Neil Posted December 12, 2018 Share Posted December 12, 2018 my god there are bees in it - what are rockwool doing - that's disgusting treatment of animals. I bloody hope they don't claim to be vegan free!!! 2 Link to comment Share on other sites More sharing options...
joe90 Posted December 12, 2018 Share Posted December 12, 2018 @Big Neil I think your right, we used rockwall and it’s nothing like fibreglass insulation. Link to comment Share on other sites More sharing options...
PeterW Posted December 12, 2018 Share Posted December 12, 2018 Rockwool is however full of dust so you do need good masks. Link to comment Share on other sites More sharing options...
Big Neil Posted December 12, 2018 Share Posted December 12, 2018 ...so why the dressing up like a super-gimp as described by Mr Harris. have I missed something? Link to comment Share on other sites More sharing options...

I don't think you've missed anything. There is a lot of difference between Rockwool rolls and Rockwool slabs. It isn't possible to stuff RWA slabs into small areas as they are rigid. I fitted a lot of RWA6 slabs without wearing any protection and without any problems. https://www.ribaproductselector.com/Product.aspx?ci=6375&pr=Rockwool-ROCKWOOLInsulationSlabsRWA45RW3-RW4-RW5-RW6 Edited December 12, 2018 by PeterStarck Added link.

Dreadnaught Posted December 12, 2018 Share Posted December 12, 2018 (edited) Sorry to change the subject slightly, but I wonder why anyone has not considered using blown cellulose in interior walls. I visited a lovely Touchwood build in Suffolk recently that will do exactly that. Is it a matter of cost I wonder? Or perhaps the concern of the circular holes required? Any thoughts?

joe90 Posted December 12, 2018 Share Posted December 12, 2018 One of the reasons may be the lack of rentable machines to blow it in unlike the USA, for us DIY merchants! Link to comment Share on other sites More sharing options...
vivienz Posted December 12, 2018 Author Share Posted December 12, 2018 (edited) When the cellulose was put into my house recently, Gordon, the guy who did the job, commented about the lack of fluffer-upper machines in the UK and Europe. His was imported from the US. Perhaps the other thing is the need to seal the walls. Having seen how easily the cellulose escapes from the smallest of gaps when blown under pressure, I imagine it could be difficult to install in interior walls, especially once services are embedded into them.

joe90 Posted December 13, 2018 Share Posted December 13, 2018 I like the look of wet cellulose, sprayed onto the walls a bit like sprayed foam, then scraped flat and plasterboarded afterwards. What machines do they need? Link to comment Share on other sites More sharing options...
