Working on an extension. Where the front door will be placed, there is no upper sill. The question is whether it is unwise to lay floor chipboard in the opening, as it can be quite moisture-sensitive there. I was considering using 22mm raw planking instead, perhaps "crossways" so it's only just over a 20cm span.
Or am I off track?

Sounds quite sensible to do so, chipboard is never good together with moisture. But you can see if you find 22*220 panel board instead, I think it's better than dealing with råspont. Is there a hole in the sill where the door is supposed to be, or am I completely wrong? It might be good to reinforce underneath in that case so it doesn't sag.
The lower sill is a horizontal 45x145, then an upright 45x145, then the upper sill at 45x145. I've cut away the upper one in the door opening; otherwise, the door will be too high. The gap between the outer upright 45x145 and the first floor joist is about 20cm (floor joists along this wall).
No, of course, there shouldn't be any moisture entering. There will be paneling, a 10mm air gap, a threshold with a threshold plate, molding, etc. But at the same time, it is an exposed area. My question is, should I confidently go with chipboard flooring, or should I install solid wood instead? Am I off track, or can I confidently use chipboard flooring all the way out?
