Yeah yeah ; bit of bs . I’ve seen the photo your SWMBO sent me ….

That was the one we downloaded from your website

@Pocster. a serious question for you. does your office block grid ceiling require attachment to the ceiling above at all? or is it only attached to the walls?

Sure you asked before . You have light weight fitting to the ceiling above ( different fittings depending on beam / timber etc ) . Roughly every 1.2m .

What ya thinking ?

I’m think I need to fit a dropped ceiling but can get fixings to the joists above due to MVHR manifold and pipes. Was hoping that the grid system didn’t need ceiling fixings. Will have to go with timber I think for this small area

You can always do the drops where you can then have a horizontal grid between them with drops off where you actually need them . If that makes sense

Unless the width is 1200mm ( 2 tiles wide) you are going to need fixings from the ceiling down to the track.

have a look at Armstrong ceilings website

I’ll measure the width tomorrow but pretty sure it’s over 1.2m wide.

I’ll see if I can get anything between the MVHR ducts. Might just be easier to do it in timber though. Will speak to my chippie

This is a pic of my current MBC TF project, and this shows the counter-battens that MBC installed, perpendicular to the joists above (hidden by the membrane but you can see where the membrane is quilted where it was first stapled to them). 

This extra 'bracing' is achieved just as simply as affixing 25x50mm counter-battens (larger of the 2 two common roofing battens) to the underside of the bottom chord. There's zero rocket-science   

Hi @Nickfromwales I’m going to batten my ceilings like this using 25x50 battens, do MBC fill in the ends where the battens meet the partition walls to support the ends of the ceiling plasterboard or just rely on the plasterboard on the walls to give the support.

I would consider upping the batten size to 38*50 or 25*75mm as the smaller ones might split. 

 

On our ceiling we didn't use end noggins, just allowed the plasterboard to sail between battens. It was held up by a 20mm sand cement layer on the walls however.

Graded roof tile battens should not split

I'd recommend the Gyplyner system. It would be very easy to install. You could use the GL6 brackets to create up to 120mm void link. Longer brackets are available too.

 

PB screws to GL1 track, lengthened using GL3 connectors. GL8 around the perimeter. GL12 is another option for the brackets.

 

Also worth Googling "Gyplyner ceiling" for more info and videos.

 

I compared suppliers and BG are more expensive but their dimpled finish makes it much easier.

 

I'm using this system with AH185 (GL2) brackets. Travis Perkins carry all the BG bits but brackets were expensive so I got those ones from Minster. I'm screwing to concrete soffit (HCF). Plasterer wasn't familiar with this system so was a little nervous of whether it would be level. I've screwed (TechFast) each bracket in place on a 3mm packer to allow adjustment, but only a couple of brackets need tweaking thanks to using a laser level during installation. I've gone a bit OTT with GL1 @ 400mm centres and brackets around 900mm centres. I think the limit is 600mm X 1200mm, so I've made a lot of extra work for myself.

 

Hi,

 

It's been a while since you commented this but was hoping if you could help me out?:)

I'm planning a dropped ceiling from the current concrete ceiling. I have found British Gypsums systems and as you mentioned "Gyplyner" sounds like a very simple, easy solution. However, there's also a system called "CasoLine MF". Do you know the difference between these two systems?

The Gyplyner ceiling is more simpler and allows more room above the ceiling with less drop. Planning to finish with plasterboards and since you have used this I was wondering if the Gyplyner is enough for residential flats??

Thank you in advance!

Here's an off the wall idea, vacuum excavation. Spendy I bet but if you don't ask...

Wrong thread?

I've seen the Casoline system one the website before and it's what the architect suggested. If I recall it has a larger minimum void. Gyplyner worked well. I used brackets like GL9 under concrete which worked well with concrete screws and packers to tweak (default 3mm then fine tuned later as needed).

 

I don't know requirements of flats
