Hi I am working with the council on my house, I have fitted a 8inch x 8 inch H shaped RSJ which has been red oxided. The council now want me to clad it and have said either double board it with normal plasterboard or use a single layer of pink plasterboard for the purpose of fire proofing.
I have some questions, first is there a reason for picking one method over the other, is one method better for some reason?
What is the best way to fit the noggins (don’t know if that’s the right word) do I just cut 2x4” so its tight and bash them in or do I glue and knock in (bearing in mind it is red oxided).
I’m assuming you knock them in so the 2” face is facing me and not the 4” face is that correct.
I’m worried that even bashed in tight that the wood will shrink over time in a centrally heated house and be loose, is that not going to happen?
I was going to knock them in every 400mm like joists is that correct?
Is there any better way of doing this that I should consider?
Any help/advice appreciated. The beam is 3.5m long
