Boarding a ceiling...

[RobbieJam]

Hi everyone, new here and looking for a bit of advice. Apologies in advance if this has been covered before.

I have done some general DIY plasterboarding in the past and have been happy with the results. I am currently doing up my house room by room and had a local builder and plasterer do the last room as it was a bit too much for me to take on but the smaller bedroom I want to have a go at boarding myself then just getting a plasterer in to skim over it.

The same builder is going to be taking the room back to brick and lat wall frame and I'm going to dot & dab onto the brick and screw boards into the lat frames. My question is are noggins really required as per this article? http://www.homebuilding.co.uk/feature/how-fit-plasterboard-ceiling

I'm sure the builder who did my big attic room didn't do this??

Sorry for the long winded post! Any help greatly appreciated.

Rob.

As long as your joist spacing is no greater than 450mm, it'll be fine. Noggins are recommended for tape & fill (which is what he's doing in the article) but you don't want to be doing that, have it skimmed.

A word of caution when removing plaster/render back to brick for refinishing; a little known regulation under Part L of the Building Regs states that if you remove more than 24% from an exterior wall (& get caught), the whole wall must be upgraded to current insulation standards! So don’t get caught out if you’re having any Local Authority building inspection on other works your doing.

I would also ask you to seriously consider a full float & set plaster finish for the walls rather than a cheapo dot & dab job!

Many thanks for your reply Richard. Ah didn't know about the 24% thing, I'll keep that in mind!

much better manufacturer's guide that the article you linked.

Fantastic, I'll study that carefully!

Regarding insulation, would any be needed on the walls at all?

How old is the property, whats the construction of the walls, solid or cavity?

1920's/30's terrace house (gable end), no idea if solid or cavity! I suppose I need to find out these things before posting

Yes it does help ; it could be single skin which is worth insulating while your going there but it's obviously more work & expense; are there any issues with or signs of damp?

If your stripping all the external walls back, your changing a thermal element & considering the age of the property, it's (strictly speaking) notifiable work & should be done to Building Regs Part L1B. You should also consider the benefit of making it compliant & having a certificate to prove it when you come to sell; the lack of one is increasingly causing problems if there is any hint that unauthorised building works have been done. LABC would almost certainly have you bang to rights under the 24% rule if they find out but tis your decision

Thanks again Richard. No sign of damp and I'm gonna find out if cavity or single skin, if single skin I'll look further into the insulation issue.

Thanks for all your advice, Rob.
