I returned the flooring chipboards at Byggmax today, the seller asked why and I replied that they were not approved to be joined between the joists. Then he said, "yes, they are, they have tongues... who said they're not?" - your own product information told me that... so don't ask for advice at Byggmax. By the way, they had raised the price of the boards so I got back more than I paid for them... and with the higher price, it's cheaper to buy approved boards somewhere else!
I'm soon going to lay flooring chipboard, so I'm wondering why there is such a fuss about joints between joists. If the center-to-center is 600 and the sheets are 2400, wouldn't the joints only end up on the joists?! If you had a different measurement somewhere, you'd lose an average of 30cm each time you're in that situation.
Or am I thinking wrong?
And who sells building elite flooring chipboard for 7-8:- more than Byggmax?

Well, if you have studs with cc 600 then the joints will be over a stud. You'll probably need to cut off a piece of the floor chipboard for each new row, on average 30 cm. Then it's not the end of the world if you miss the stud by a few cm somewhere. It's not like Byggmax joints are on the verge of breaking and therefore absolutely need support.
If you have 600cc, you can just splice the joists, and Puhos or Kronospan P6 is probably harder than Contifloor (Byggelit) since their v20 corresponds to the P5 class. However, if you have an old house like we do, the joist spacing can vary, so we chose Contifloor to achieve smoother installation and avoid a lot of waste.
The boards are harder and better than byggelit in that respect.
If it is possible to splice the studs, then you obviously do so because this provides the best strength. It might be that Puho believes that the joints between the studs, as done by byggelit, are not good enough, even if a joint that meets the classification and is approved can be made.
Of course, you can use byggelit and still splice the studs, but the question is whether it's worth anything extra that the joint is better?
