Chipboard flooring - Some questions

[Nygge72]

Hi, we have removed a hallway carpet in our house from '72, and will try to fix some creaking in the floor. The creak sounds like it comes when stepping on the board between the joists.

I have some questions about our chipboard flooring.

What is the reason for laying them alternately whole and split (see image)? Is it to utilize the board's length maximally, or is there some construction-related reason for doing this?

On one side, you can clearly see the start of the board, while on the other wall you can't see this. Does the board still end there, or is it possible that it continues under the wall?

If one were to take them up to glue/screw them down, is there anything one needs to consider? (To get rid of the creak).

Thanks in advance from someone who's never worked with chipboard flooring before.

Chipboard flooring should not be joined over the same joist bay, hence the offset. Additionally, material waste is naturally reduced; what's cut off in the first row is essentially used in the second.
Whether the wall is on the chipboard is impossible to say; you’ll need to check the situation. Otherwise - glue to the joist, glue in the tongue, screw it down.

Aha. So if you take them up, the new ones should be offset in the same way.

Is there any specific glue to use and how close should the screws be set? Is that something you know about?

Wood glue, distance screw type 20. There are probably instructions from the manufacturer online if you are unsure.
