Timber Cladding over render detail

[Kernow]

We are going to be having a section of timber cladding over render on our build. 
Cladding will be open joint random widths, over a black tyvek membrane. 
 

How has everyone dealt with the bottom detail where the cladding and render meet? Has anyone used aluminium trim, so that you don’t look straight up behind the cladding, and also to tidy up the bottom edge of the membrane? Or have you just let the membrane flap and rendered up behind the timber?

 

We will be having aluminium trims over window heads etc, so not a problem to get more made up. I’m also aware that we need to keep the cavity behind the boards ventilated. 
 

Any info would be appreciated. 
Thanks

You could use a James Hardie top ventilation strip the other way up nailed to the bottom of the battens.  Render up to it and let the timber cladding overhang by 30mm.

I don't think any creatures would be interested in living behind that, unless the gap is wide.  Alternating draughty, damp, freezing scorching . A mesh trim will only close the bottom, so not much point.

I would go aluminium trim, with a little kicker at the front, the cladding should sit 3mm off the trim so water doesn’t wick up the cladding.

That will look good and especially if there are wobbles, chips and scrapes on the timber edge.

Thanks, yes I had thought of an aluminium trim, was just wondering if anyone had any examples where they had done similar. 
 

No worried about mesh etc as like you say save a steadying, likely too draughty for anything to live in there
