OSB boards throughout the house

[anders07]

And you don't think there's glue in plyfa...?

OSB is often glued with adhesive containing formaldehyde which, according to some research, emits carcinogenic fumes (there have also been articles in DN about it). OSB glue releases more gases if they become damp (even with high humidity).

Plyfa is glued with moisture-resistant glue and probably also releases some less pleasant substances but only a fraction compared to OSB.

I wouldn't want OSB in the walls of my house...

Turn the tables and think that OSB should be standard in a well-built, new house.

Now ask yourself if you want to be penny-wise and save a few tens of thousands and then have to live for 50 years in a house with more cumbersome hangings, poorer sound comfort, etc.

Edit; The additional cost for plywood shouldn't even be relevant here, it also doesn't provide any improvement sufficient to justify the price increase imo.

It completely depends on which plyfa you choose. Moreover, OSB only contains 2-3% glue. A fraction compared to particleboard, which many have as subflooring. I would rather have OSB in the walls than particleboard in the floor in that case.

Strange.... This report states that it is exactly the same amount in birch plywood as in OSB. (however, the average value for OSB is miscalculated and should be 0.525)

And that they seem to be glued with the same glue type, UF.

But... You can't just bring up facts.

*Warning! Irony above.*
I like facts. Personally, I have installed OSB in all the new interior walls we've built except in the bathroom where it was 15 mm plywood according to våtrumsvägg 2012.

Strange.... This report actually states that there is exactly the same amount in Björkplywood as in OSB. (however, the average for OSB is miscalculated and should be 0.525)

Fantastic if they have switched to better materials. I read up on glue/solvents about 8-10 years ago when we renovated the wooden house we lived in then... It wasn't a pleasant read back then...

I chose OSB boards for the entire house for 62,000 including labor, thanks for the help!
