End-jointed sparse panel worse load-bearing capacity?

[Johan-]

There is a big price difference between full-length sparsely paneled 28x70 compared to short-end tongued sparsely paneled 28x70. The question is whether the load-bearing capacity is significantly worse even if I ensure that all joints are placed over alignment boards (28x120) on both sides of the floor joists (75x230)?

Do you have sparse paneling on the floor?

What are you building?

I am installing underfloor heating, which involves spacing panels between the aluminum plates that the PERT tubing is laid in. That is, spaced panels on the floor joists, then a layer of floor gypsum and thereafter 14mm oak parquet. (of course, also plastic and felt paper in the right places, but that doesn't relate to the load-bearing capacity).

Assuming the rafters are about 150mm cc, it should be fine, just make sure to place the joints in different locations.

Run with c/c 200 on the hose, which means c/c 100mm for glesen.

I can't see that it would make any significant difference in bearing capacity if you use end-matched sparse paneling. If you position the joints as you write and naturally stagger the joints... But I'm not going to bet my life on my answer... but I would do it that way myself... without even thinking much about the difference in bearing capacity...

I can't see any issues, just make sure the joints end up in different places.

Don't know why I wrote this. Everyone else has written the same thing.

Thank you for the answers, it made it easier to make a decision. By the way, I've seen glespanel 21x120 but have never tried walking on such a floor.
