Hi, first post here so please bear with me! I am going to block up an internal doorway with a stud wall. The door is out, and the frame has been removed. I can see a lintel, so thats a good start! My question is relating to the width of the CLS timber I need. The doorway is brick width (100mm), plus a bit of render and 2mm plaster coat and I plan to use sound proof plasterboard at 12.5mm thick. So if I use 63 mm wide CLS timber and screw two sheets of plasterboard to it I end up with a new width of 88mm. Which is way below the original brick width. If I use 90mm wide timber and add two sheets of plasterboard (25mm) I end up at 105 mm which is proud of the brick! I will get the whole room plastered, but what is the best way to go about this ? Thanks in advance

Agree, masonry would be better but we would use fibolites.
You'll get better thermal values with timber studs (with insulation between them).
Do you think this will be an issue when all of the remaining wall is masonry?
I would be more concerned with the issues of differential movement and cracking when using a timber stud against masonry.
The only way to overcome this (if you do decide to stud) is to carry the plasterboards onto the masonry by 150mm or so and dab this part of the plasterboard to the masonry.
When we did with an internal wall in a renovation last winter, bearing in mind the wall was stripped back to masonry, was to stud the opening and plasterboard the studs so that the boards finished flush with the masonry. We then dabbed the whole wall making sure that the boards fully carried the opening whilst applying dab to the existing boards - i.e. a double board sandwich over the opening.
Not sure I understand your point?
The rest of the wall is poorly insulated so don't bother about the rest?
It's not really that hard to avoid.
Building an opening back in lightweight masonry does not mean it will be poorly insulated does it?
I agree cracking can be avoided but it is time consuming. We build using both methods but it is more reassuring to know there is masonry across the whole wall.
