Sealing timber cladding/reveal around window?

[junglejim]

I’m cladding my timber frame house using thermo ayous. I’ve tuned boards to make reveals  for the windows that butt up against the frame. I’m wondering whether I should run a bead of silicone sealant sling the joint for weather tightness?

Silicone probably will not last very long and may discolour.  Can you do it without?

Yes no problem without but wondering what others do?

I plan to use the external Soudal SWS sealant

Leave a gap, it allows it to dry out quicker if it was to get wet. 
mat risinger did a video on this on YouTube, it was found that sealing up every gap kept moisture in rather than letting it in briefly and out quickly.

Thanks Russell that’s helpful and exactly what I was wondering.
