I know, these are the ones I bought. Still, there is danger of splitting if one drives in too many 5 mm screws.

I don't think this is an issue because the space above where the drywall will be is insulated well. First, there's the 50 mm celotex, then two thick layers of fibreglass. The boards will not be colder than the air in the room and so there should not be any condensation within or above them. So...

Thank you Bof. Isn't increasing the thickness of the drywall enough to prevent sagging?

Two problems with the metal ferring. First, it is not designed to be fit on top of celotex. Second, it will lower my ceiling which is not high as it is. Is there anything wrong with just using a thicker drywall between joists that are 600 mm apart?

What is to MF it?

The existing joist positions are marked. What do you mean by "also the legth joints if possible"? About the cavity, do you mean the cavity that will be between the celotex and the drywall?

But what does it mean to counter batten it out?

The celotex foam boards and the drywall boards are the same size: 2,4 by 1,2m. Do you mean that I should not put a drywall board over a celotex board but should make sure that they end on different joists?

Thank you for the advice, but I don't know what "mf ceiling in" is. I cannot put the original ceiling down as it is part of the loft space which is communal. All I can do is what can be done within my own flat and that is fixing drywall on top of the celotex. (I believe that by celotex you...

I don't think that predrilling will work because of the 50 mm insulation. It has to be a long drill going through foam that is not exactly solid and there's no guarantee that the screw will go into the tiny hole after going through all this insulation again. Besides, this will complicate the fixing.

Counter batten it out?

Thank you guys, I posted it here: https://plasterersforum.com/threads/specific-drywall-installation-issues.77684/ . It is in the General Discussions on Plastering and awaiting approval.

I must fix drywall onto my ceiling and I have two problems that are related. First, there are 50 mm thick foam insulation boards fixed on my ceiling already and this means that the drywall must be on top of them (well, below actually). This, in turn, means that the screws must be very long. I...

Thank you for welcoming me guys. I wasn’t kicked out of my house, I emigrated. The price I got for selling my house in Sofia, Bulgaria, was barely enough to buy a flat in Glasgow, UK. Now I joke that I traded a big property and a small girlfriend for a small property and a big girlfriend. (My...

Hi guys, I am a diy-er who sold his house to move into a flat and is missing the diy opportunities that a house yard brings. Still, there are things one may do even in a flat and I am not talking about binding books or knitting. I used to weld, I have to work with wood now. I used to pour...
