Browse Forums Heating, Cooling & Insulation 1 Dec 30, 2013 11:30 am Hi, We are building with Redink in WA. They usually install that foil stuff in the walls (apparently, only some walls, others have nothing), but, for whatever reason, they didn't do that with our's (we've had a lot of trouble with the bricklayers/quality of bricklaying, so it may have something to do with that - either they didn't trust them to do it properly or they forgot to do it in all the kerfuffle!) Anyway, they have said that they will pump insulation in via holes in the external walls instead (these walls are going to be rendered). My husband was talking to some tradesmen at work today and they advised that we look in to the pump-in option, as problems can arise due to the fact that there is no longer a cavity in the walls (I think he said damp issues). I know that cavity wall insulation is a normal thing in the UK, where we are from, but WA obviously has a very different climate to the UK. As an alternative, one person suggested that we ask Redink to double insulate the ceiling instead (they do insulate that as a matter of course). Does anyone have any knowledge or advice on the pump in stuff that they can share with me? Thanks very much in advance. Re: Cavity Insulation 2Dec 30, 2013 2:36 pm I don't know and I note that you are in WA which does some things different, but I thought there are two things, foil for primarily a moisture barrier and some reflective insulation, and some kind of thick insulation for, well, purely insulation. Like one is a woolly jumper and one is a waterproof windcheater type thing. Two related but not identical functions. Not that I know but that's been my understanding. Honestly, these "we've made a mistake but we have a shortcut way of fixing it" things give me the heebiejeebies. What is your building inspector recommending will work?

Yes, I know what you mean - I feel we've had a bit of that. They even said, because our mortar wasn't mixed or used correctly (although they wouldn't acknowledge that) "if it still hasn't set when you're in we can repoint it down the track". I don't think so!! We haven't employed an official, proper inspector, but a family friend with his own large and very successful building business and years of building experience has been looking at it for us. We'll ask him next week, when everyone's back at work. If he doesn't know for sure he'll know someone to ask I guess. Re: Cavity Insulation 4Feb 04, 2014 5:55 pm Hi Mandy, Sorry to hear that your builder has forgotten to ensure the brick layers installed the insulation in the walls. Lucky for you it has been picked up. There are many, many houses in Perth where it has been missed and forgotten about entirely! I am fairly sure that we are installing the Rockwool Cavity wall insulation on Monday 10th Feb. We have been installing cavity wall insulation for over 15 years into all types of cavities, and have never had any problems with water transfer, as the product is water repellent and we bring it directly from the UK, use UK equipment and have adapted the UK installation technique to suit the way we seem to build down here. Our installers will be there first up Monday, feel free to come and see the 'magic' happen , i will be there to around 8-830 to see how it is going and catch up with the guys. Hopefully they have yet to render the outside, will check later tomorrow. PM me if you have any additional questions. Stu Hey guys, what’s everyone opinion on James Hardie linea direct fix to frame?
