OSB or masonite?

[tosso]

Which is preferable? I have the impression that OSB is better when it comes to hanging heavy things on the wall if you have the board behind the plaster.

Are there any advantages of masonite compared to OSB?

 

[MathiasS]

I have never heard of masonite being used behind the drywall? OSB, plywood, or chipboards are usually the alternatives.

... or maybe råspont?

You don't mean plywood? Masonite probably doesn't make a difference in that context. A completely unnecessary cost, both in money and time.

Chipboard I mean, but it's the same thing as masonite, right?
Anyway. I had verbally agreed with the seller about OSB, but the contract stated board behind gypsum, and then I got chipboard :/.
In other words, I'm stuck. I still have to darn well look for studs if I'm going to hang up e.g., a wall TV

No, particleboard is particleboard and masonite is masonite.

Masonite is what you most often encounter as thin flimsy boards in brown color, the same that is usually used as back panels on furniture.

If you have particleboard behind the drywall, everything is fine and dandy—you don't need to look for studs when you want to put things up on the wall.

MDF is even stronger, but if you're going to hang things with reasonable weight, chipboard will hold.

OSB is better for attaching things than chipboard. However, drywall + chipboard is admittedly better than just drywall.

Chipboard - Good
OSB - Better
Plywood - Best

The plywood crumbles the least, and the chipboard crumbles the most when you screw into it. In plywood, it doesn't matter much which screw you use, but for the other two, you should use a fairly coarse-threaded screw, especially in the chipboard.

I got lucky one day, I had ordered chipboard to put behind the gypsum, but received plywood at the same price. It would have been more expensive for them to drive back and exchange it.

You must mean OSB?
There's no sensible person who puts MDF behind the drywall, right? MDF is twice as expensive as OSB, the boards are heavy as hell and don't hold screws as well as OSB.

MDF is used for visible surfaces that are to be painted, such as window recesses and various built-in furniture, shelves, and carpentry.

 

[Mats]

There are those who actually use MDF. Because they feel that it's too unpleasant to work with OSB.

 

[tosso]

From what I've seen, the exterior walls are covered with MDF board behind the drywall. However, I will get particleboard in all interior walls . I would have chosen OSB but the contract stated board behind the drywall, so I got particleboard. I've learned to always specify every little detail in future contracts. However, I'm going to buy plywood to hang my TV on. Better to be on the safe side

For example, Eksjöhus offers masonite as an option behind the plaster. Then 9mm thick.

Is it really so?
Feels like you can attach much more to OSB/rough-sawn boards than particle board.
So why doesn't everyone use particle board when it's much cheaper?

Is it really cheaper with particle board than OSB?
I was thinking of using OSB behind the plasterboard, but started to hesitate when I saw the price - 25kr/sqm plus VAT...
Or have I simply gotten a bad price?
