NewToAllOfThis Posted July 31, 2021 Share Posted July 31, 2021 Pro's and Con's of boxes and mounting method please. We have 47mm service void on external walls and will be using 9mm plaster board. Internal timber frame is 89mm depth, again plus 9mm plaster board. All want to use plasterboard boxes, two want to fix the boxes prior to plaster and one after walls are plastered. Interested to know if anyone has had any other type of boxes fitted and the Pro's and Con's for each solution. Link to comment Share on other sites More sharing options...

Oz07 Posted July 31, 2021 Share Posted July 31, 2021 I've never had a problem with plasterboard boxes but a lot don't like them. @ProDave is in the trade and think he is happy with them. I've never heard of these being fitted before boarding/2nd fix surely it defeats the object? Link to comment Share on other sites More sharing options...

ProDave Posted July 31, 2021 Share Posted July 31, 2021 Plasterboard boxes come in different types and different makes. Some are dire and likely to give problem. I always use Appleby, sold by Screwfix and Toolstation and they are the best I have found. If you really want, you can get (from TLC direct) plasterboard fixing metal back boxes. I prefer to go and cut the back box holes before the plasterer goes to skim, at least I know all cables are present and connect and the boarder has not "lost" any of them. If you really really really hate plasterboard boxes, you will need your joiner to fit dwangs (noggins) at the correct depth to fix ordinary boxes to.

If you have chosen lousy boxed that barely clip into place, then no, don't think of fitting them before skimming. Link to comment Share on other sites More sharing options...
Onoff Posted July 31, 2021 Share Posted July 31, 2021 Neatly cut the boxes with a multitool so you don't lose too much of the pb facing paper. Paint the cut edges with PVA and allow to dry ideally. It really strengthens the hole and stops it breaking up. Then fit the box. Who's got time to do that though unless you're doing it yourself! ? 2 Link to comment Share on other sites More sharing options...
