Interior wall thickness?

[Tstrom]

Hello
Building an extension to the house...
How thick should I preferably make the interior walls?
Should I use wall studs 70x45 or 95x45?
How deep is a standard frame for an interior door?
I don't want the frame to be "thicker" than the wall, do I!?

Regards, Tomas

If it is not a load-bearing wall you are going to make, 45x70-timber is usually used. If you have single-layer drywall on the wall, the total width becomes about 95 mm. I have a note that standard dimensions are 93, 100, 118, and 147 mm to be able to experiment with different studs and paneling.

Shouldn't just have single plasterboard. Either plywood plasterboard or double plasterboard. It becomes much sturdier and much quieter. Add insulation too!!

As an alternative to plywood+drywall, OSB board+drywall can be mentioned. I believe OSB is cheaper, or am I mistaken?

OSB is much cheaper and almost as good as plywood.

OSB is barely cheaper than plywood and worse.
Standard thickness for frames is 93mm.
Even 68mm is fairly common, but thicker ones usually have to be ordered.

I buy OSB for 119SEK per piece but plyfa for 149SEK.

That is much cheaper than "barely" cheaper.

...and if you are using chipboard/plywood/OSB + drywall, it is recommended to glue + screw the wood panel to the wood studs. This significantly stiffens and allows adjustment of crooked studs. Use "winter glue"

That only applies to those building bank vaults, right?

Plywood for 149!!
Do you live at the lumberyard or what?

Does anyone have a recommendation in Stockholm?

The OSB board is not entirely dimensionally stable. It should be mounted with a certain distance between the boards. 30:- difference is not that much, I think.

MathiasS:
Where do you buy the records, by the way?

 

[Johan Gunverth]

That's only for those who build bank vaults, right?  

Nope! My cousin builds houses full-time and wouldn't hesitate for a second to glue the wooden boards when building his own house.
- It takes twice as long and becomes too expensive for the customer, he says in response to why house manufacturers don't do it.

Sorry, I looked at two different invoices, one with VAT included, the other without VAT. So far, I have paid 149+VAT for the plyfa, nothing else, which further supports the argument that plyfa is unreasonably expensive. The OSB price was with VAT...

But if you can glue the OSB (and it's obviously good), then this issue with form instability can't be a big problem. Gluing OSB should be a safe way to get walls that bow?

I've used OSB everywhere, without setting with margin, and haven't seen any issues with it?
