Does hardboard (Masonite) work behind drywall?

[pwb]

I find fiberboards that do not contain added glue to be appealing both for environmental and health reasons. Would it be possible to use it instead of OSB behind the drywall? That is, with the purpose of having a wall that is easy to drill into and hang things on? Or is hard board too crumbly/weak to work?

The most common glue-free alternative behind gypsum is råspont. A wood fiberboard like masonite is not very suitable for screwing into.

Tongue and groove boards are clearly the best option but also the most expensive and labor-intensive.

Masonite behind the gypsum doesn't provide anything, better to use double gypsum if you want it glue-free.

Råspont is of course the best option but also the most expensive and labor-intensive.

Most labor-intensive yes, but not necessarily the most expensive. In my house, they've used scrap wood for the walls (prefabricated inner wall elements). This doesn't cost much at all but works well enough even though sometimes it happens that there isn't any load-bearing capacity, but then you just move the screw a couple of centimeters.

I posted in another thread here on the forum a few years ago:

In my house (from the 40s), there is masonite on tretex on the walls. Personally, I think masonite is hell to both screw into and nail into. It's as hard as concrete.
