so it seems that i have many more questions about MF ceilings and walls as i fit out our basement. so i thought i'd just start an MF questions thread rather than multiple individual threads. i'm sure that some of these questions are very beginner questions (as that's what i am!) but i'm here to learn. 1. can i attach resilient bars to MF5 (top hats)? all the articles on the web seem to state attach resilient bars to joists and no one seems to do it to a metal frame ceiling. i don't see why not but wanted to ask to be sure. 2. when building a GypLyner Single lining system on walls with doors, how do you go around the doorway? the white book shows a window reveal but nothing about a doorway! https://www.british-gypsum.com/documents/white-book/british-gypsum-wb-gyplyner-single.pdf . i have a double width doorway and a single width doorway to navigate with my lining.

Awesome. That Ilbruck PU700 is a PU adhesive and stuff stays stuck when I’ve used it before.

the BG white book states but what happens when you can't suitably fix very well? our cemfloor screed sits a little away from the wall due to the perimeter foam for expansion and so if I want to use a minimal gap between the MF base channel and the wall I don't really have anything to drill down in to without it blowing out the edge of the screed? without want to do that nor wanting to unnecessarily reduce the room size just to get a good fixing point down I was wondering if I could use construction adhesive to fix the base channel down? I have loads of this stuff (https://www.illbruck.com/en-gb/products-systems/product-finder/pu700-multi-use-construction-adhesive/) which sticks very well! I'm thinking that with the GL1 studs being attached to the walls then having the base track simply glued down might not be an issue? what do folk think?

Out of interest, can you lay Amtico on some form of underlay to remove any small imperfections on the underlying floor? Or does it not work that way?

I’m doing all that other stuff too!

this is a great question! our planning stipulated free draining driveway so we had to have permeable sublayer so rather than putting down loads of hardcore/type 1 to only have to remove it later we dug down the required depth and filled it with what will be the final subbase layer and then put terram on top and a 100mm layer of cheapest hardcore on top of that for the lorries to drive on.

I'm sound proofing as much as I can our music room. I decided to put 100mm RW5 above the double boarded ceiling to try and reduce the bass as much as possible. At 100kg/m3 I'm hoping it will do the job. but.....for anyone considering using it, it is a massive pain to use! it's so dense it's not flexible at all so it's more likely to get gaps between slabs. if I were to do it again I would seriously consider adding an extra 50% of insulation and use RW3 (so 150mm RW3) I'm so glad that part is over and I'm on to plaster boarding now.

made a start on this. there are, inevitably, gaps between the plasterboards. is there any point filling these with acoustic sealant when the second layer of boards below are going to be staggered? if so do I just squeeze on a bead and press it in with a filler knife? or is there something special that needs to be done.

does that integrated white goods? like dishwashers, ovens, microwaves etc

and i thought you were such a nice guy! despite what everyone else says 🤣

assuming that's one of the invoices they ask to see though, right? i thought they only ask for a select number of invoices these days with the online submission

good luck. I'm just collating all our invoices. currently up to 561 and only up to June 2024.

Welcome back. Hope you’re refreshed after your hiatus. I also learned loads from your posts so thank you. ☺️

yes! this is what i use mine for. 🙂 although i override often in the winter as i want the rooms to heat up to save me heating them

I had similar thoughts to you when starting our journey. In the end I took the advice of many on here and our UFH is just one zone and is controlled by a wireless thermostat in our open plan kitchen. The house is a pretty constant temperature and there’s no need to adjust heating with individual room thermostats. obviously my Loxone switches tell me the temperature I just don’t do anything with it! maybe one day I’ll see if I can get a wiring centre hooked up and average the temperatures of all the rooms to call for heat from Loxone. But, tbh, I doubt it. It works just fine as a simple heating solution.

Blimey @nod those welding clamps are blooming marvellous! Best tip I’ve had in ages. Thanks. (No @Pocster!! Just no 🙄)

Don’t worry. Ordered jack-point screws and welding clamps from Amazon for delivery tomorrow by 1pm. Gives me time to walk the dog and do a bit of plumbing before they arrive!

Oh. One more question please @nod the BG video says to use jack-point wafer head screws but I’ve only got drywall wafer head screws. these are the screws I have. Are they ok to use? or do I need the jack-point screws?

Cool. So as I suggested and how @crispy_wafer did it. Good to know! I’ve just been using normal grip clamps which seem to do the job. But I’ll see if Screwfix have any of those you suggest.

Has your ceiling fallen down yet? If not then that’s good enough for me! 😂

@nod looking for a bit of advice please. when extending the MF7 primary channel on the MF ceiling BG says to do it like this. so the pieces are back to back. but this causes an issue for me as I've already attached the hangers to the ceiling in a nice straight line and so the hanger is now on the wrong side to attach to the MF7! e.g. do you move the hanger so it's on the other side (a pain as I've already hung them) or can I put 2 pieces of MF7 the same way around butted up to each other and use another piece of MF7 on the other side to joint the two pieces together? obviously adhering to the 150mm overlap so the joining piece is 300mm long. hope that makes sense!

welcome Tim. that's exactly what we did! as have many others on here. it is daunting but you soon learn after lots and lots of reading on here. 😉 i started a blog but i lost my way with it after a while as i became more hands on and didn't have the time to maintain it. but it might give you hope that if we can do it anyone can!

yeah. sorry. i don't think i explained myself very well! 1 x 1.5mm T&E cable for the 230V lights going to a spare relay completely separate from the 24V/tree stuff 1 x 1.5mm T&E cable from my Wago terminal blocks 24V block to the 24V on the Loxone tree spots 1 x Cat6A cable with green/green&white to the tree of the spots and a.n.other pair to the retractive switches with the orange/orange&white going to the 24V of the retractive switches or presence sensors etc. make sense? or am i talking rubbish as usual? 🤣

damn! something else to consider! 🤣 was just discussing it with swmbo (well not so much discussing more using her as a sounding board) and I realised that I am having some 230V wall sconces for additional lighting so I might as well just run T&E for the power requirements and a single Cat6A cable for the control requirements. so will only be 3 cables which isn't too onerous. now you've thrown a spanner in the works with the dimmer compact I'll have another think about the lighting design.

different coloured lighting can affect people's emotions, e.g. blue to help focus, red to calm etc. so when recording being able to change the colour of light can help someone if they're struggling with getting something recorded. as such, I would like RGBW somewhere in there. LED strips would work but the lack of drivers/space in the cabinet precludes that unless I want to do a massive overhaul already and add a LXN-2 underneath the existing cab (which I don't!). I have a PS&B and the current usage on most of the fuses is nowhere near the max so I can easily run some 24V spots. I also still have one fuse unused so have plenty of headroom there for me. which is why I thought the expensive Loxone tree RGBW spot route would just be easy for me as a quick solution. I'm leaning towards the 2-core 1.5mm for ease of use again. the cost difference is negligible so it'll probably come down to my own laziness and an easy life will win over. it's just there's the voice at the back of my head going "what if you want to put 230V lights in there later and need an earth?". trying to run that later would be a pain! so maybe I do just run normal T&E. have you used the Loxone RGBW spots? wondering if their claims for the smooth dimming are true. also I found some posts on the Loxone forum that mentions the spots WW were only 38° spread and not very bright, but I think they were the Gen1 spots and someone else responded with that wasn't their experience! so, again, just looking if anyone has used them and can give a review.
