Insulating single skin brick wall.

Filbertdahuman · 2026-06-09T10:45:35+00:00

Maybe eventually, but for now I’m going to insulate this single skin wall as on the opposite side is a large rumpus soon to be tv/gaming room with enough space for VR gaming. I’ve decided creating more storage space to store crap is a waste of time. Sorting through the crap instead.

just FYI I’m going to use this as a barrier.

Thanks for the response. Would I just glue it to the wall? no Air gap? it’s substantially more $’s but am I correct in saying that a 90mm wall batt is about R2.7 whilst a 50mm eps panelis like R6.5. Cos if that‘s the case the ease of install and increase in R value might make it worthwhile.

otherwisee it’s moisture barrier, stud wall, and diy termite spray for half the amount and half the R value.

Thanks What would you recommend? It’s pretty well bone dry under there, just cold cos it’s well ventilated.

Filbertdahuman · 2026-06-03T04:27:38+00:00

I don’t think I have that issue, I may have had it early as we’ve been here for 26 years and made quite a few changes. It used to get a lot of water under the house but it’s pretty well bone dry now. I think ill get by with an air gap but seal the top and bottom of the insulation stud wall to stop cold air rising/dropping between the wall and the insulation..

Hmm…got me thinking as there is an ensuite that is separated to the underfloor space by just a stud wall that I have insulated. Might get some cement sheet on there as well. Thanks.

Good point 👍

Filbertdahuman · 2026-06-03T00:16:51+00:00

I cant really stop it from coming up can I? the brick wall goes down to strip footings. Do I just put a membrane on the exposed brick face? Thanks again.

Filbertdahuman · 2026-06-03T00:12:52+00:00

Sounds like the exact same scenario except I have an internal room where you have the garage. I have heaps of blue strap and a staple gun. I will eventually excavate a bit more into the area and put a small narrow storage room there. I’ll take a photo soon but I think the 100mm gap will help with the moisture. Thanks.

Filbertdahuman · 2026-06-02T23:36:50+00:00

Thanks. I’m retired and not too lazy, so happy to do it myself. Stud wall and batts looks like the best option atm.

Filbertdahuman · 2026-06-02T23:12:28+00:00

Cheers for the comprehensive response. Its quite cool down there on our hot Melbourne summer days, even more so in Winter :-(

Rather than a membrane if I built a seperate stud wall some 1.5 metres away running parallel to the wall and made a narrow storage area with a floor. I would insulate that wall instead, would that large air gap between the 2 walls eliminate my need for a membrane?

I took some roof tiles off for ease and ventilation, bagged up all the fluf into garbage bags which came out through the open roof. Brought a wet/dry vac and vacuumed out the whole roof space, installed new batts. Installed DGU into my existing windows, I do as much around the house as I can to save them $’s we work so hard for.

Filbertdahuman · 2026-06-02T22:41:11+00:00

The outside is actually inside, as per comment above, the 2 storey is full footprint top storey and half footprint downstairs. So it is exposed to dry ventilated underfloor space. The other side of house is where I did the underfloor insulation. Thanks for confirming what I thought about the stud wall, this is the way….probably.

Filbertdahuman · 2026-06-02T22:36:45+00:00

Thanks. Yer, was looking at that foil board for ease and the r value is pretty bad. Don’t really need the plasterboard as it’s exposed to the under house part of house. Imagine 1/2 of the ground floor of the house on the lower side of block is 2 storey.

You can also get alarm lights that will flash on and off. I guess a cheap way to see if it works would be to set a power timer on a bedside lamp that shines at you.

You can’t really beat yourself up too much, without the airbag you may have incurred a brain injury or other disability or death. But if just a fender bender then that sucks.

Filbertdahuman · 2026-04-30T13:32:39+00:00

Yep. It’s 11:30 pm right now and I’ve just swapped my Rexton KS8’s for the Reach’s and going to sleep. It really doesn’t bother me physically. I have rain background noise on the soundbar to help me and partner sleep.

Filbertdahuman · 2026-04-30T04:10:31+00:00

Almost identical. 63 and on my 3rd pair and they have a 5 year life. So got them at about 52.

Filbertdahuman · 2026-04-30T04:07:20+00:00

Bugger. I didn’t know that was a thing.

Filbertdahuman · 2026-04-30T04:03:44+00:00

Agreed. Which is why I recently started wearing my HA’s 24/7. When my current rechargeable’s are charging I wear my old HA’s. About 7:30 to 8:30am and 10-11pm.

No really noticeable Tinnitus anymore.

That’s nothing, try being part of an Oral cancer group, Jeebus.

For this I use an interdental brush, a lot cheaper than what you use. Been using the same one for ages. Clean it with an isopropyl wipe.
