OSB board or equivalent externally. Is it possible?

[Atom]

If one is considering building a larger storage shed, around 25 sqm, that they want to erect as quickly as possible, is it okay to use OSB board on the exterior?
After 1 or 2 years, cover it with proper fjällpanel or wood composite.
The most important thing is that it should be quick and not cost a fortune.

No electricity for 5-7 years. Heating on occasional nights in spring/autumn with a small stove.

Yes, it will last a couple of years, then it's just to send it to the dump.

Hmm. Asfa then? Or do you know other materials?
Oil-hardened masonite?

OSB seems to last quite a while.

They had been untreated for 18 months.

I've seen that in the USA they use OSB instead of exterior gypsum (under the facade, that is). They seem to like it. But I don't know which OSB class it is.

It should work just fine to use OSB as siding. The rabbit cages I built from OSB in 2009 and painted with red paint will last for many more years.

Faluröd?

As long as the boards are protected from water, they will last a long time. With Asfaboard, you don't get such a stable frame without battens and paneling. An alternative could be exterior gypsum.

Faluröd?

Yep.

I had asfaboard (with external nail battens on) over a winter on the garage. I thought it looked pretty fresh the following summer and just built it in then. But it certainly had buckled a bit. I don't think I would have wanted it unprotected for two years, so to speak.
