My first floor is only 2.4m but my ground floor is 2.6m. I have attached my wall make up

Hi All I am planning on using metal stud for a couple bedroom and landing partition walls I was planning on using 70mm stud but the builder has plenty of 50mm stud that he doesn't want and said I could have My plan was to use the 50mm stud, 2 x 12.5mm soundbloc plasterboards either side with 50mm acoustic insulation in the middle Would this be suitable? Many Thanks

Ground floor screed is 50mm thick with 200mm PIR beneath First floor is spreader plates Quite well insulated, ceilings are 0.12 and walls are 0.18

I am in the process of ordering all my stuff for the UFH (upstairs and downstairs). I have been quoted for Heatmiser Neostat v2, NeoHub Gen 2 I have been looking through the forum and I have seen people have had issues with these thermostats…one issue being the backlight randomly coming on. Could anyone recommend any other possible thermostats that would do the same thing? I would like them wired and be able to control via smartphone Many Thanks

Hi All I am just sorting out my loft insulation out I have 8" x 2" ceiling joists and I am thinking 200mm Isover spacesaver between joists and 200mm isover spacesaver over the top...does that seem a normal way to do this? The I need to cover is 78m2...is it just a case of ordering 156m2 of 200mm Isover spacesaver insulation? I have looked into warm roof but this is the way we have decided to go Many Thanks

That is perfect! Thanks again @Iceverge

I will having insulation (rockwool type) between the rafters and then 100mm PIR underneath so was going to use the battens to firmly hold the PIR on and give me a batten for the PB to fix to and a service void if needed Or i could just screw the plasterboards direct to rafters (through PIR with 150mm drywall screws) Many Thanks

Regarding battening and plasterboarding Would people recommend battening horizontally at 400 centres (using 3 x 1" timber) Would then using a single 12.5mm standard wallboard be OK to board the ceilings with? Or would it be better to batten vertically (to follow rafters at 600 centres) and use 15mm wall board? Any advice greatly appreciated Many Thanks

I will check this, many thanks

Rafters are at 600 centres I will make sure I put some solid timber (got some spare rafter timber) between the restraint straps, thanks for that.

Thanks again, yes I will keep updated. This is it currently

When I say 120mm Rockwool, think I will going 2 x 60mm rocksilk as suggested

Thank you very much @Iceverge I had also carried out these calculations and this just confirmed my decision. I am going to go with 120mm Rockwall between the rafters then 100mm PIR over the top. how many screws per PIR would people allow? Would 12 be enough? Do I have to ‘join’ them on a rafter like plasterboard? Many Thanks again for all the comments, very much appreciated

No this hasn’t been done yet, this is my job for next weekend (if my tower turns up)

Sorry for the lack of info regarding the ‘felt’ it’s a new build and I don’t actually know what they put on? I will most certainly ask

I will be going with 120mm Rockwool over 50 & 70mm option Above the rafter is roofing felt, slats and tiles Cheers

Thanks for all your help I am just trying to decide on which way exactly to go 120mm Rockwool between rafters (or 70mm + 50mm Knauf onnifit as that's what my supplier has) Do I 25mm batten horizontally with 25mm PIR taped in between and then 75mm PIR over the top? Or just 100mm PIR straight over the top?

Just to confirm you guys would use 120mm Rockwool between the rafters and then 100mm PIR over the top instead of 75mm PIR? Rockwool would be a lot easier to fit and provide a nice tight seal around brackets etc

Hi All I am planning to start insulating my vaulted ceilings and just ordering all the materials i need for it My plan is to install 120mm PIR between my rafters (rafters are 170mm), they 75mm PIR laid horizontally beneath. I will then either 50mm batten it and plasterboard it or just plasterboard depending on what we decide on lighting I am just concerned about the lengths of screws needed to install the plasterboard or battens....is this normal? I have seen you can get 120mm drywall screws (I am guessing these are ok if i don't batten it) My main question is what screws/fixings are the best to use for installing the 75mm PIR to the rafters? Can i just use 100mm wood screws with penny washers or is that a bit cowboy-ish? I will be taping the 75mm PIR joints...do i need to tape the 120mm jointers over the rafters or not? Many Thanks

I don't suppose you have a picture of it at all if you wouldn't mind sharing it (just to show the mrs) Many Thanks

Hi All Over the next few days I will be making a start insulating my vaulted ceiling I want to 'flat' off the top of the ceiling so i can use this as a void to run cabling and MVHR ducting (I've attached some example pictures of what I mean) Apologies for the daft question but I just want to double check...what is the best way to make sure these are all level and run perfectly in line? And also the best way to fix them? Many Thanks

Just thinking, when I 'flat' off the vaulted ceiling I could run the ducting through that and mount the spigot so the valve is in the flat bit of the ceiling Many Thanks

Just to add, the ceiling rafters are now up and the builder recommended installing the 120mm PIR from above while I can Many Thanks

Hi All We are having MVHR installed in our new house (well I am installing it) and we are having vaulted ceilings in 2 of the bedrooms I have attached my very dodgy drawing of my first idea of how to install them with battens etc Is this a suitable way of doing it? Or is there another/better way to do this? Could I potentially wall mount the valve? Any advice very much appreciated
