2x2 for a stud wall?

[Ian H]

I have a room that isn't really big enough to be a bedroom but is too big to leave as a hallway/landing.

I've used 4x2 on the other walls I've built but wondered if I could gain a couple of inches in the room by using 2x2?

The wall will be 2.3mtrs tall, 2.4mts wide, have 1 door and be partially fixed to a staircase. I can get good fixings into the ceiling, floor and both walls to the side.

Is 2x2 an option or just daft?

I lived in a house that had internal partitions made from 2x1's used with the 2" length parallel with the partition, so the whole partition was 50mm thick, I know because I witnessed my house being built, they were perfectly rigid and no one would ever have known, people were amazed when I proved it by measuring them. Though people will tell you here that that is no good but if every cm counts they'll be fine.

2x1, now you've got me thinking . How did they manage to get a door casing in that?

I was thinking 2x2 at 300 centres with the stronger blue or pink plasterboard would be pretty decent. But 2x1 with a deep architrave on the inside......

I think they were like a weedy mdf, going back about 15 years now, but this was a developer site with a few hundred houses so they'd have had some specials made up no doubt but I don't see why some planed softwood wouldn't suffice.

Are you concerned about building regs?

 

[endecotp]

I've just looked it up; even with insulation it requires a minimum of 75mm.
That's assuming that this is a "new building".
(Approved doc E, sections 5.17 and 5.18.)

It has just struck me that 3x2 timber is actually not 75mm, it's about 68mm. Hmm, I wonder if anyone worries about that?

 

[Ian H]

Are you concerned about building regs?

Only because I have to be.

Building control are involved with the loft conversion so might be interested in this wall. It's not a new building but will be a new part of an old building. The wall was previously 600mm further back and made of those brittle hollow 3" blocks.

Wait till BC sign off then stick your wall in.

 

[Ian H]

Can I do that with doors too?

A girlfriend lived in a student house where all the walls were t&g wood panels
You could hear the mice fart but it worked to retain what heat there was

I's stick it in after it's been inspected

 

[Ian H]

I'm ready to build the wall now, just need to think no about the door and it's frame.

Could I fit a 2ft 3" door in there or will I have to have a 2ft one?

I have 745mm between the other wall and the bottom step and plan to have the architrave starting on the stringer (?).

Couple of pics of the area:

Cutting off the bottom of the stringer?

 

[Ian H]

Yes, going to cut it off then fix it back on further back.

But I'm not sure if I can fit the frame for a 2ft 3 door and still have an architrave on the other side.

Use 38mm CLS longways and 12.5mm plasterboard, and its OK.

Seem unlikely, yes. But why would that matter to you?
