Browse Forums Building Standards; Getting It Right! 1 May 14, 2022 12:23 am Hello I am replacing a ceiling in an old house. The original ceiling joists aren't straight (up to an inch out) so I can't attach plaster board directly to them. My initial thought is to use the Rondo 301 battens with direct fix clips to level the ceiling. However I have looked at AS 1684 and it mentions that the ceiling must be directly attached to the joists to contribute to the frame bracing. It also says "Suspended ceiling systems shall not be assumed to provide diaphragm action to transfer wind loads to bracing walls." Has anyone managed to use a direct fix system and it still count towards the structural diaphragm of the building? What alternatives have people tried other than timber battens (levelling the timber battens would take alloy of time) Thanks Re: Direct Fix Battern Ceiling - AS 1684 Racking Forces 3May 17, 2022 1:14 am You don't get much bracing from plasterboard sheets, BUT you do get some! If you have access into the roof space, why don't you install binders to the top side of the bottom cords of the trusses. (Long length of timber 4.8m etc laid on top of the ceiling joists, nailed through the binder into the joist) We are Expert Consultant's, and we are here to help.

But I'm not sure… 3 6729 Thank you @ashington Homes for your reply! They just got back to me and offered credit for me to just take it as is. It was a less than quotes I got from ceiling… 6 2915 |
