expansion joints - thincoat jobs

Looking at a couple of bungalows where the top of the gables to the apex are to be renderboarded - running through into the lower level masonry.

Reps say i need expansion joints where the bottoms of board and block meet. Already know customer won’t want it.
Does everyone do this? Feel like i never see them in.

Cheers

It's an expansion bead for a purpose though it will keep cracking forever

correct meant to have an expansion.
but also the renderboard section should be ventilated.

i have done what you are doing and rendered the lot under customers orders. but havent heard anything to say any cracking has occured

yes iv heard this too. What’s best way to ventilate it? One rep said be better to build out the top section with lats then board it so it has a overhang detail with a mesh bead at the bottom to let the cavity breath…

If you saw the job it wouldn’t work wouldn’t look right.
