JKami84 Posted April 8, 2022 Share Posted April 8, 2022 Hi - I assume these are natural. Most are way smaller , even seamless, than the ones in pic. The ones in picture are 'worst' of them. What is used? Only because I always like to research / pick better product than my builder may use. The plasterboards are acoustic, so would like to maintain highest level of acoustic soundproofing that is achievable. It will be skimmed then painted at the end.

Bitpipe Posted April 8, 2022 Share Posted April 8, 2022 In my experience joins are taped before skim and that fills the gaps. If they are particular large you could use LE foam and trim flush before taping (which seems to have happened in the bottom pic). Link to comment Share on other sites More sharing options...
Conor Posted April 8, 2022 Share Posted April 8, 2022 Perfectly normal. They'll be taped / meshed / beaded and set in place with a base coat before the final skimming. Link to comment Share on other sites More sharing options...
JKami84 Posted April 8, 2022 Author Share Posted April 8, 2022 Thank you for reassurance its normal. Poor guy must have struggled with the weight of acoustic plasterboard so a couple of 2-3mm gaps isn't a problem. Foam is interesting - and i've seen Acoustic filler foam available.... Worth it?

We did in around all the door frames so there were no air gaps in the walls. Didn't bother between plasterbaord gaps as they weren't big enough and we have acoustic wool in the walls anyway.

ProDave Posted April 8, 2022 Share Posted April 8, 2022 You should see the horrors on some sites where the boarders leave burst boards, and much bigger gaps than that "The tapers will sort it" Link to comment Share on other sites More sharing options...
bassanclan Posted April 8, 2022 Share Posted April 8, 2022 You can get acoustic sealant which is a bit like silicone sealant used in bathrooms. Your builder definitely won't do it, but it's something you could do if you are very worried. Personally I'd just leave it Link to comment Share on other sites More sharing options...
nod Posted April 8, 2022 Share Posted April 8, 2022 They are fine Just tape and skim Link to comment Share on other sites More sharing options...
Adsibob Posted April 8, 2022 Share Posted April 8, 2022 If you are using double layer of plasterboard, and have staggered them, these gaps will be completely inconsequential from a soundproofing POV. Link to comment Share on other sites More sharing options...
