Studio wall detail
Posted: Fri Apr 30, 2004 5:28 pm
Hi all,
I am currently designing a small to medium sized studio -(that I am going to start building shortly) and have a few questions about my wall construction.
I don't have pics yet so I'll give an outline-
The space is about 100m2 -control room is roughly 30m2, studio area is the rest. Building will consist of concrete slab floor, 190mm (8") concrete block walls about 2.8m high with a pretty standard gal iron, gable roof (200 x 50 rafters etc.) sitting on the block wall. Roof extends to about 4.5 m in centre. The main studio area is about 9.5 x 7m. I was going to float the internal floor(s) on rubber pads, pine studs 90 x 45 on end with two layers of t&g chipboard flooring sheets, one layer 10mm plaster in between them. On this floor, I'm planning perimeter internal pine stud walls (90x45) about 30mm away from blocks with 25mm MDF and 2 layers 16mm firestop plaster (all on internal side of frame with rock wool behind). With the ceiling I was planning on sealing off the gal roof by screw and glueing MDF/plaster on the roof battens in between the rafters and then run RC directly on the bottom of the rafters and hang two layers of fire rated plaster then fill the gap -(about 200mm) with insulation.
What I'm not clear on is how I should seal off the gap between the block wall and the internal (floated) wall at the top. This would be about a 30mm gap. Obviously I don't want to couple the inner wall to the blockwork, so maybe rubber? or timber to make the gap smaller first then cork or rubber?
I'm also not exactly sure how best to fasten the inner wall. Fine to glue and screw it to the Floated floor, but at 2.7m high will need some support at the top without touching the external structure or the ceiling? I was going to run the wall up close to the ceiling and seal the gap there with caulk.
Any suggestions on would be greatly appreciated.
Cheers
