Partition walls: what is the best way to build them

[MariaD]

Looking for advice on internal partition walls as I'm feeling a bit lost

I’m exploring internal partition wall options and I’m a bit overwhelmed. I’m considering things like:

• Fermacell

• Gyproc Habito

• Lightweight aggregate concrete blocks (e.g. Thermal Liteblock)

• Solid gypsum blocks

• AAC blocks

• AAC floor-to-ceiling wall panels

• Standard concrete blocks

• Magnesium Oxide panels

• Cement boards

• Double Plasterboard: given the cost of boards like Fermacell, you could install 2 standard plasterboards

If I go with board-based systems like Fermacell, should I use metal studs or timber studs?

I plan to do the installation myself, with help from friends.

What I’m looking for (in order of importance):

1. Durability – ideally walls I’ll never need to worry about, something well-built that I can leave for my children.

2. Noise absorption

3. Impact resistance – sturdy walls that can handle everyday wear and even support cabinets if needed.

4. Ease and speed of installation

5. Low complexity – which option minimises the number of steps and processes from start to finished wall?

6. Humidity resistance – ideally walls I don’t need to worry about, even in wet rooms.

7. Most durable finish – some systems are better suited to certain finishes or renders. Which one gives the most robust, long-lasting finish?

8. Wall thickness: some system may allow me to build partition walls 8cm thick

9. Weight – I’ll have concrete floors, but lighter is still better.

10. Cost – saving money is good, but value matters more. If a system is twice as expensive in materials but more durable and twice as fast to install, I’d still go with that.

Any advice on the best overall system for my priorities would be really appreciated.

All our internal walls are wooden stud, 3x2 for non structural 4x2 for structural. Lined with plasterboard. 50mm insulation in the 3" and 75mm in 4".

 

Easy to do, all materials readily available.

8cm thick

3x2 with 12.5mm end up 95mm thick.

Water resistant plasterboard in wet rooms.

Mine are all dry lined, as are most in Scotland, zero issues for me.

You have so many priorities you are that you are confusing yourself 

you are not going to get the best soundproof wall and build it cheaply. 
if you want speed then by pre fabricated cardboard panels that are used in offices, will they be sturdy and robust ?

nope not at all. 
you need to narrow down your priorities. 
you say you would like to build these, then what are your skills, block laying or carpentry. 
 

all my internal walls are 90mm studwork with 11mm osb both sides and 15mm plasterboard on top. 
rather unusual but it does what I want.
