Hi all first post �� Be nice!

Bought our house 4 years ago, its liveable but theres lots I want to do,
but with 2 kids 2 & 4 its hard to find the time.

Ripped out the bathroom around 2 years ago, really happy with how that turned
out!

Next project is where I need some advice, Im starting on the living room in
4 weeks, currently 6.0m long 3.6m wide.

The plan is create a living room approx 3.6 x 3.6, a study approx 2.4 x 2.4
the rest of the space will be a mid landing.

I started ripping plasterboard off to get a head start on the stud walls, the
2 external walls were fine no issues, 1 external wall was fine, my first issue
and questions are around the second internal wall which connects to our
neighbour, there are 2 boards deep, im assuming fireboard and plasterboard.

As I plan to re wire as I go and I also need to move a rad my questions a

1. If I rip down all board, do I need to replace both? Or can I just replace
fireboard? As I will be skimming Im assuming I could skim on top of either.

2 if I need to replace both are they staggered to improve strength?

My second set of questions are around the stud walls, when the plasterboard
came off Ive found that where I need to set the stud wall Im not in line
with any of the existing uprights and there are no noggins in the wall, there
are also pipes running where I plan on putting one of the walls, my questions
a

1 will the new stud walls be strong enough with the base timber bolted to the
concrete floor below and the top timber bolted to the ceiling joists, with
uprights at 400mm centres? I want to avoid putting noggins in the wall if
possible as it means I will have to unnecessarily re route some pipework to
get noggins in.

Im using 3€�x2€� c16 timber for the stud work, and I have 6€�x1€� to
put noggins in the ceiling to fix the top timber of the stud wall to.

Hope thats enough and not too much info.

Look forward to your replies.

Ben

Next project is where I need some advice, Im starting on the living
room in
4 weeks, currently 6.0m long 3.6m wide.

The plan is create a living room approx 3.6 x 3.6, a study approx 2.4 x 2.4

Building regs will typically specify dual layers for extra fire
protection between dwellings. You also need to consider noise
insulation. Replacing both layers would be very sensible IMHO.

Have a look at approved document B:

https://assets.publishing.service.go...ouses_2019.pdf

2 if I need to replace both are they staggered to improve strength?

Yes - and flatness.

My second set of questions are around the stud walls, when the plasterboard
came off Ive found that where I need to set the stud wall Im not in line
with any of the existing uprights and there are no noggins in the wall,
there
are also pipes running where I plan on putting one of the walls, my
questions
a

1 will the new stud walls be strong enough with the base timber bolted
to the
concrete floor below and the top timber bolted to the ceiling joists, with
uprights at 400mm centres? I want to avoid putting noggins in the wall if

get noggins in.

Fixed top and bottom only is not uncommon - many modern houses seem to
have stud walls inserted wherever without much attention to how they fix
to existing structures.

You can double up the studs at the adjoining end to add some extra
stiffness.

However I would be tempted to stick some more substantial noggings into
the ceiling and adjoining wall to create proper fixing points. They
don't need to be full stud depth though, so you should be able to dodge
the pipes with a nogging in front of or behind etc. You can always add
extra packing pieces to make fixing easier.

Alternatively you could add some stiff bits of Bat strap or similar to
allow the end stud of the new wall to be fixed to the two nearest studs
in the perpendicular wall. That's thin enough it can be lost in the
thickness of the PB.

Dont assume. MIGHT be just two plaster for sound insulation.

a

1. If I rip down all board, do I need to replace both? Or can I just
replace
fireboard? As I will be skimming Im assuming I could skim on top of

Or use celcon blocks? better sound proofing and easy to cut channels for
wires and pipes in.


2 if I need to replace both are they staggered to improve strength?

They will be for sound as well.

Mmm. Strong yes, stiff?....I am concerned. 2.2 meters plus, floor to
ceiling is a long away to go and stay straight against a lateral load,
like someone leaning againsts it. Shame to end up with cracks because it
moved a couple of mm

Any way you could use, instead of noggins, say, a steel plate screwed to
existing wall and bolted to the end stud?


Im using 3€�x2€� c16 timber for the stud work, and I have 6€�x1€� to
put noggins in the ceiling to fix the top timber of the stud wall to.

Hope thats enough and not too much info.

4x2 is more normal for internal stud except the lightest and shortest run

6x1 sounds OK.


Look forward to your replies.

so far so good. I can't comment on the BR requirements for the party wall, only that you need to address both fire & sound. Sound transmission can be reduced several easy cheap ways

Is this property fairly modern and timber-framed ?. If so,
are each of the 2 boards grey in colour and 12.5 mm thick or is
one a pink colour ?.

Pink plasterboard is called fireline and is reinforced with fireglass.
It gives an hour of fire resistance (but it is the whole structure that
provides the protection not just the choice of materials).

If not pink, it might by green or blue, one of which colours is
soundblock plasterboard, if this is a party wall.

Whatever is there should not be changed, in fact, I'm not sure why
you are disturbing the deeper layer. Is is water damaged ?, or
are the two layers bonded with something that might be soundblock
goo or intumescent seal.

This sounds like a party wall in a modern timber-frame house, in which
case you probably should not be tampering with it at all.

If that's the case, why is the OP pulling it all off?

At the very least, talk to your neighbour and let him know what
you are doing, but you should have given them notice of the works
well in advance. The Party Wall Act is well defined. Plenty of
books on the subject in every reference library.

If you have interfered with the sound and/or fire resistance of
the party wall then you need to have a party wall agreement with
the people on the other side. If you don't, they would be able to
sue you and you would have to pay all their costs, plus any
damages.
