Hello.

I am going to build a house of 172 m².

The house supplier wants 60 thousand to install OSB boards in all the walls of the house.

I think they are asking for a lot, what do you think?

Please help!

Can't say if it's a lot or a little, but I would have thought it's easily worth it! Invaluable when you're putting up shelves, a TV, and pictures on the walls and don't have to deal with gipsplugg.

Actually sounds a bit expensive, but at the same time, I can imagine that this is an option that is difficult/impossible to easily fix afterwards, which allows the manufacturer to add a bit extra. Personally, I regret not using Plywood on all the walls instead of OSB. Much more stable and not that much more expensive...
 
If you have 240 sqm of wall surface, 60,000 SEK means 250 SEK per sqm. That's not an unreasonable cost, right? But I agree with Kallebo, choose K-plywood instead, it's much better.

I don't think it sounds that bad.
But if you measure around all the walls, and on both sides of partitioning interior walls, you might get an idea of how much OSB board you'll need.

But why do you want OSB everywhere, just because it's trendy?
I've lived my whole life without a square centimeter of OSB, and it has gone pretty well anyway.
Unnecessary expense, I think :thumbdown:

I also estimate that it's at least 240 sqm of wall space, and then <250 SEK/sqm is not entirely unreasonable. However, it's not a great price. The board costs about 50 SEK/sqm, so labor and screws for 200 SEK/sqm might be somewhat excessive.

Don't expect there's a chance to get the work done for less than 100 SEK/sqm considering all the processing and hole cutting needed for doors, windows, wall corners, electrical boxes, etc., as is the case in a typical house. You can't get through many boards per hour; it's not like boarding a sports hall or warehouse directly.

However, I disagree regarding plywood. It's a waste of money to choose anything other than what's cheapest between OSB, chipboard, or plywood, which makes OSB the winner.

I put OSB everywhere, not just because it's easier to hang things on the walls later, but also for soundproofing and the sturdier feel in the slightly more solid and firm walls. It's noticeable when the teenagers start slamming doors.

If it had only been for the sake of mounting, I might have hesitated about the cost and effort.

I paid about 18,000 SEK for OSB in a house of 167 sqm. But that was without labor, I put up the OSB myself... It took me as an amateur about 3-4 working days.

If your OSB costs 60,000 SEK, and 20,000 SEK of that is for the OSB. Then it's 40,000 SEK in labor costs.

Two carpenters could solve it in a maximum of two days. That gives an hourly rate of about 1,250 SEK per person.

They should solve it faster though...

So cheap, no.... but home suppliers are rarely the cheapest way to go either. You pay a bit extra for a complete concept.

I estimate it to 400m2, which gives 150:-/m2.
Which I think is reasonable.
 
What is the alternative? Double gypsum? If the walls get a different thickness with OSB, then door and window frames, etc., need to be adjusted, so it is not an unreasonable cost.
 
Choose plyfa instead of OSB. OSB is worthless for putting things up on.
 
I would also choose plyfa, OSB is more unstable and additionally it's a bit questionable if you want OSB in the walls considering the potential glue fumes they release...
 
You can get a lot of plugg for 60 lax

And you think there is no glue in plyfa ...?

There is no reason whatsoever to spend money on fantastic plywood in a villa; OSB is perfectly adequate for attaching most things you can think of.

I also think the upgrade is great, but you don't need it everywhere. Keep in mind that ALL interior walls grow by 25 mm, which actually adds up in the end. You can use OSB on one side or also bridge with OSB between the studs.
