Particle board floor

[radman]

I know that the floor chipboard is 22mm thick, but if you space kitchen floor joists at 30 cc + noggings, can you then lay the following flooring:
1. Chipboard 12mm (tongued and grooved)
2. Gypsum board 12mm
3. Tiles 6mm

The problem is that the solid pine floor is 30mm and I need to get the kitchen floor to the same level.

Far too flimsy with such thin chipboard, it won't be stiff enough to lay tiles and you've also forgotten to account for the adhesive!

Hijacking the thread a little..

We are going to install underfloor heating in the kitchen and have bought grooved chipboard. The joists are cc60 and are on top of a concrete slab. Previously, it was some type of plank and parquet on the floor which flexed too much, and now we are worried that the floor will not be stable enough with only chipboard and laminate. We have a whole bunch of regular 12mm chipboards standing by that we are considering laying double and then chipboard on top. A total of 50mm, that is. What do you think about that? Shouldn't the floor be stable then? And how do we fasten it all together?

Thanks for the answers :0)

If it is enough, I cannot assess, but if it is to be stiffer, they must be glued together over the entire surface; otherwise, nothing is gained with that solution. Is it possible to insert a beam between the existing ones so that it becomes cc30?

I cannot judge if it is sufficient, but if it is to become stiffer, they must be glued together over the entire surface; otherwise, nothing is gained with that solution. Can't a beam be placed between the existing ones to make it cc30?

Unfortunately not. We have all the electrical and plumbing installed in this floor.

I have myself tracked the floor chipboard 22mm on cc 60 beams and laminate in the kitchen. I don't think it's a problem at all that it would flex. However, I would make sure that the turns end up on a beam or reinforce it in some way. There's not much left to hold up. I didn't do this in the kitchen, but I will in upcoming rooms. I tried standing on a turn on one leg that landed under a cabinet and it flexed with my 80kg and it held, but I didn't dare to jump. However, I avoided stepping on the turns during construction until the laminate floor was in place.

I have 22mm tracked floor chipboard on 60cm centers with laminate in the kitchen. I don't think there's any problem with it flexing. However, I would make sure that any turn lands on a joist or reinforce it in some way. There's not much left to hold it up. I didn't do that in the kitchen, but I will in upcoming rooms. I tested standing on a turning point on one leg that ended up under a cupboard and flexed with my 80kg and it held, I didn't dare to jump. But I avoided stepping on the turns during construction until the laminate floor was in place.

But TS is going to lay tiles, and it must not bend at all because then the floor tiles will crack or come loose.

Not going to lay tiles anymore. Abandoned that idea after 85sqm of tiles on the basement floor. I'm sick of tiles now..

But we still want a solid floor though

That post was directed to teamlundver

So if I do it like this:

1. Glue the joists, lay down 12mm particle board, screw it down
2. Glue the entire particle board, lay down the next 12mm board, screw it down
3. Glue the entire particle board, lay down 22mm flooring particle boards, make sure the joints aren't in the same place, screw it down

Is that correct then?

Honestly, it would feel more right to lay proper chipboard at the bottom that is screwed and glued. It should stabilize better than the first layer of 12mm chipboard.

And if you are really after a stable floor, let the 12mm chipboard wait until the next project and lay a new layer of chipboard crosswise over the first layer..... It's probably overkill and a bit unusual, but it should be very stable. More expensive but stable.

 

[teamlundver]

it's clear. the thing is that we have these 12mm chipboards so it won't cost us anything extra. The idea was to have 2*12mm boards and then a 22mm flooring chipboard.

Can I attach it as described above? Will it be correct?

 

[MathiasS]

If you were to go with what you have, I would still place the floor particle board underneath, I think, and then screw-glue the other layers.

 

[teamlundver]

though the floorboards are tracked to underfloor heating..

 

[cecar33]

And should therefore be on top so that the heat spreads more easily upwards with the tracks across the beams.
