Tbh 6 people using this to shower and proper ventilation is a must which is stating the obvious! (Reminds me I must sort out my bathroom venting not that we're using the wet room corner yet. Oddly enough I want to do something "different" ).

I believe they have been round and made various promises but nothing's happened. I'd like to think he has written correspondence of it all but likely not. I've a small dehumidifier I can lend him. He reckons the vent unit is a single room MVHR but I have my doubts on that.

I'm doing all I can to help him sort it asap without actually going there! Flat roof above the ceiling he's just said. Was asphalt but repaired a while back (and painted silver). Tenant above has potted plants on it, so much it looks like Epping Forest to quote him.

Housing assoc. apparenty. Not too good it seems so he's taken it upon himself to sort.

Occupied? Him the missus & 4 daughters currently using this!

Mate's rented place. He wants to fit a new bath & re-tile. He's stripped the tiles above the bath and reckons there were some hollow tiles and that the blocks behind are damp. First couple of tiles were a bitch to get off, rest more or less fell off. This is an external wall. Brick facade externally. He can't access that to check any mortar joints as a neighbouring glass roof. At this point he doesn't know whether the damp is coming through from outside or has penetrated through the tiles. They do have a shower handset in the bath so this wall (the tiles) get wet. Tbh my money is on the tiles letting water through: He has a working Envirovent in there. Flat roof above that has been repaired. His plan is to overboard. I've told hin to use moisture resistant, (green). Before: With the tiles removed: He's already bought the new tiles & bath. If he hadn't I might have suggested "multipanel" type board. My gut feel is to tank the wall with Everbuild Aquaseal but will it stick to damp walls? Is there anything else he could use? I remember using a liquid dpm from Wickes you applied in two coats. The second one you threw sand at to give a key. Does he need to "stabilise" the walls in any way? One option is that I have an unused tube of Feb Blue Grit he's welcome to. This is made by Everbuild who make Aquaseal tanking membrane and tbh, other than the grit in it the blue liquid element looks and smells the same. At the mo he's just cleared the debris and rigged a temporary shower curtain so they can continue using the shower. Any suggestions for him to move forward. Cheers

Good blog entry here ref Icynene:

There's a Hell of a lot a waste to trim off level with the timber frame if I recall. Gauging how much the stuff will expand must be nigh on impossible. I did my small shed, well the floor and two walls as a bit of an experiment with cans. Got so bored in the end I did then other walls with EPS.

I encased my horizontal 110mm soil pipe in spray foam within the base of the stud wall. Aqua Panel over that then tiles. I was advised here that Rockwool slabs might have been better. End result is more than I could have hoped for, it's silent. Loudest bit is the flushing in the pan. Refill is near silent helped I'm sure by the ex studio acoustic foam tiles I lined where the Geberit frame sits.

PIR no good if any chance of damp. EPS is the kiddie for damp, that's why all the passive brigade put "300mm of eps" under their slabs.

Clay flower pots are an option for "hoods". Hole in the top though...

Double post!

I originally had a lovely, airtight vcl between the ceiling pb and underside of 145mm joists. Multiple penetration now with said downlights, speakers etc. At each downlight I've carefully removed the pir in between the joists leaving the foil. You can just see the green vcl. The Thermahoods will be stuck down to the pb with intumescent mastic then the whole thing foamed in. Flexible metal conduit will come out from the foam into proper conduit. I'm aiming to this bond the Thermahood edge to the cut edge where the vcl is, to go some way to reinstating the vcl. The Thermahood will become part of the vcl in effect. I can't do that with the body dryer so I'm going to line the vertical edges over the blue vcl with Asbestolux type fire proof panelling. All edges again will be intumescent sealed. This'll then be capped over with pink pb on an intumescent foam seal and a slab of pir over that. All screwed down for future access to the body dryer terminals. (Red Commando jobbie is a test plug from when I took it into work to try). This'll be wired again in galv conduit back to the board.

I've used Thermahoods. They do low profile ones. Gets expensive if lots to do. I saw something similar in Wickes the other day. https://www.thermahooddirect.com/product/thermahood-th-095-square-low-profile-downlight-cover-pack-of-10no/?

I have a steel staircase construction book that may help you. You have a pm.

It's not a diy option afaik.

Hope you're going to stain that ply...

So if does 60'x10' at 1" thick. That's nom 20x3m so 60sqm. A 25mm sheet of pir is about 2.9sqm call it 3sqm to make it easier. So 20 sheets. Call it £10 per sheet. £200 all in. 3 times cheaper than spray. Check out Icynene. @PeterStarck had it done.

You'd have thought the government would have stepped in. Pretty sure in Oz that home PV generation has long, well for the last few years at least, exceeded what they buy from the grid. Must make for some nervous electricity suppliers and in turn the government through lost taxation.

I find it strange the project has failed... https://reneweconomy.com.au/solarreserve-abandons-huge-solar-tower-and-storage-plant-near-port-augusta-93885/

We occasionally get the most horrendous smell in the area. Someone said it was "silage"? Really wouldn't want to be dragging that in!

@Moggaman, chuck "mvhr bonfire" in the search box (no quotes) and a few interesting threads will pop up. There's chat in "Why Insulate?", "MVHR Intake", "Carbon Filter" etc.
