OSB or chipboard?

[almby]

Starting a new thread on this, I think.

If I want support behind the plasterboard in the garage, why should I choose OSB boards over particle boards?

Price-wise, particle boards are much cheaper than OSB. But here on the forum, OSB boards are highly praised as the best option. Pros and cons?

Chipboard is much "Deader" than OSB..... OSB has large fibers that bind the material together to a different density than chipboards do....
Have you ever attached something movable to a chipboard? Then you understand what I mean.

Or if you hang a slightly heavier object on a nail in a chipboard, that nail will soon start hanging downward after a while.
In an OSB, the nail stays much longer. Then you can imagine what happens with screws.

Particle boards can (should) be glued to the studs and provide an incredibly stable and strong wall. OSB moves and is not suitable for gluing. They are 1197 for the 1200 measurement for that reason.

By the way, I've never thought about poor durability in particle boards. With pre-drilling, there's no problem hanging a heavier item on a nail in the particle board.

I know two carpenters who are currently building their own houses and are installing high-quality particle boards behind the drywall. - No crappy plywood (OSB) in my house!
They use it mostly for temporary covering and walkways on the floor joists.

Plywood is, of course, the best but costs accordingly.

Nice to know that there is no science in construction technology and building materials

I screwed up my kitchen 7 years ago on chipboard+gypsum board walls without noggings. As far as I can see, the cabinets are still there. I probably should have made a complaint about the chipboard when they were so good...

Here are some silly questions, if anyone has the energy to answer:

What is OSB? What is plywood? What is particleboard (or I suppose I actually know that but what is the difference)?

Gunwerth: "No crappy ply (OSB) in my house!"
Does that mean OSB is some kind of plywood?

There are those who install rough boards, is that unnecessary or...?

Is there any variant that can be installed where no drywall is needed on top?

Particleboard is essentially wood that has been ground into a coarse powder, mixed with glue, and "baked" into panels.
Plywood consists of thin sheets of wood (veneer) that are laid on top of each other with glue in between, usually with each layer perpendicular to the previous one.
OSB is something in between. You could say it's large "flakes" of wood that are baked together.
Particleboards become completely smooth, so you don't need gypsum for even walls there. However, gypsum is good for fire safety.

Good description.

The Swedish name for OSB is egentligen strimlespånskiva which quite well describes the material itself.

The English name OSB is short for oriented strand board.

Interesting with the positive environmental aspect of OSB.

The chipboards are completely smooth, so you don't need plaster to get even walls. However, plaster is good for fire safety.

But it's not just to get smoothness that many put plaster on top of OSB (or chipboard for that matter). The wall becomes more rigid and soundproof. It simply adds more quality feel to the house.

I screwed up my kitchen 7 years ago on chipboard + gypsum walls without noggings. As far as I can see, the cabinets are still there. I should probably have complained about the chipboards when they were that good...

I also screwed up my kitchen directly on chipboard + gypsum. It's rock solid. I also have shelves and other things that are directly screwed into the wall. Works great. I see no reason to use anything other than chipboard. Would be the positive environmental aspect of OSB mentioned above if that's true.

I know someone who had to build with requirements for low emissions due to severe allergies, and he couldn't use particle board at all. I don't know if OSB was okay though....

On the construction sites I work on, we always use plywood, but maybe we get paid for it too.....=)

I know someone who would build with a requirement for low emissions due to severe allergies and he could not install chipboard anyway. I don't know if OSB was okay though....

When it comes to Byggelit's chipboards, they have a response:

Do chipboards contain a lot of formaldehyde, is it dangerous?

There is unfortunately a widespread misconception that chipboards emit large amounts of formaldehyde. Some are also unaware that formaldehyde is a very common substance that exists in small amounts everywhere in the free air. Formaldehyde is present in varying amounts in, for example, natural wood, fabrics, paints, fruits, soaps, shampoos, adhesives, glue, paper, etc. Tobacco smoke emits large amounts of formaldehyde, in fact, this substance is practically everywhere in our environment.

Chipboards are one of the most monitored products in this regard. The truth is that the low emission value required by the Swedish Chemicals Agency for the Swedish market is 0.13 mg per m3 air in indoor air. Byggelit's production is under continuous control through agreements with the Swedish Testing and Research Institute, SP, regarding formaldehyde content and emission.

To ensure that our products always meet the lowest values, we maintain full production control at all times. The average emission from Byggelit's chipboards is considerably lower than the permitted limit value and is close to what untreated natural wood emits. Byggelit's chipboards are SWAN-LABELED.

Also consider the strength you want in the wall, how heavy the items you want to hang up are. An OSB board is 11mm and feels much tougher than a 12mm chipboard for lighter/medium weight items, on the other hand, you can go up to 22mm chipboard if it's kitchen wall cabinet type you intend to install - or double glued OSB if you need to hang up the car on a stand.

One advantage of OSB is that it is very water-resistant. For example, you can use them as a temporary covering for the joists and then as a base for the gypsum. A chipboard cannot handle that.
