We are planning to build a vocal/drum booth in a factory building that has
been block partitioned into media studio units. We are trying to achieve an
STC rating of around 60 with particular emphasis on bass transmission
reduction (e.g. bass drums). Both myself and my partner have any previous
building experience the plans we have have been culled from various
sources on the net. We would appreciate any feedback about their possible
effectiveness or suggestions for improvements.
With reference to our plans we are seeking advice about the following:
Wall Questions:
Are there any gains to be made in alternating MDF and plasterboard
Are 25 gauge steel studs going to be strong enough to support our walls
What are the steel studs and tracks attached to (i.e. do we need to build a
frame for them or can they go directly onto the ceiling and floor) Also,
what is the recommended way to attach them in order to preserve the
decoupling effect
Could you recommend anywhere that we can find drawings illustrating the
best construction methods for joining stud walls at the corner
Re: staggered studs, does it matter if at any point stud in the two walls
are parallel to each other
What sort of glue is used to glue plasterboard to MDF
Is there a preferred method for screwing MDF to studs
Floor Questions:
Is the sand fill idea acceptable as an alternative to using concrete
How would the STC rating compare if our floor was floated on neoprene studs
as opposed to the 705 rockwool
Is 4" of 705 sufficient to float floors in this way or would different
thicknesses and densities fare better
Should the rockwool need to be glued to the floor or does it need a frame
to keep it in place (not attached to the structure of course)
Is our floating floor going to support our room
Is our floor joist spacing ok
Ceiling Questions:
Is there a particular spec for the resilient channel that we need to look
out for
Will the resilient channel support the shown thicknesses of plasterboard.
Will it be acceptable to attach the top leaf of plasterboard only to the RC
and glue the rest to the top leaf
General Build Questions:
We need 1 powerpoint inside the booth to be taken from the outside room.
Would it be better to run this cable through our floating floor or through
the wall
Our booth is slotting into an identical existing space and we are confused
about the order in which we need to build things. Our current rationale is
to build the floor and ceiling first and once they are in place, build the
walls. What is your opinion about this
Many thanks in advance.
