Browse Forums Renovation + Home Improvement 1 Feb 23, 2020 4:43 pm We have the typical Perth double brick home built in 20111 prior to insulation being required to be installed in double brick walls. Should have done it then but now looking at the possibility of retrofitting. Insulguard Cavity Shield https://insulguardinsulation.com.au/cavity-shield/ looks to be the easiest in terms of a retrofit. Anyone had any experience with the installation and cost? Anyone have any suggestions on possible downside?

You either need to remove sheets and anticon (not easy) or they have to drill walls to blow it in. I looked at the blow in cavity insulation when I was building (it's much easier during the construction process) but opted for standard cavity insulation in the end. There is also the Knauf rockwool version that seems comparable however the one you have referenced seems to answer much of the concern around moisture and it looks like it would fill better. Edit: Just looked through their whole site and they say they don't have to drill walls. They must have to pull screws and roll up sheets at intervals to access the cavities.

We are building and opted for double glazed windows, R5.0 insulation batts and anticon roof blanket but have no insulation for our walls so this looks like it might be a good option. Re: Anyone installed InsulGuard Cavity Shield? 6Feb 24, 2020 9:46 am Thank you both for your responses. Much appreciated. We didn't end up with anticon either - builder didn't recommend it back then (one of WA's best supposedly????) Looks like the main issue will be making sure they refit the Colourbond properly I am saying that double brick has similar thermal performance due to thermal mass effect. It will be still very interesting to see the state of your framing after 10-15… 10 29740 Hey guys, what’s everyone opinion on James Hardie linea direct fix to frame? Would this be the most common method and anybody ever had any problems down the track? 0 5132 Firstly, if your house is still under builder's warranty (10 years in Victoria) you should have no need to crawl into roof space but let the builder handle it, unless you… 3 5633 |
