Hi all,
i been busy get my build underway, which has been a bit stressful.
I have a question about battens, the construction -
Timber frame,
9mm OSB
vertical battens to create a ventilated cavity,
12mm render carrier board,
and render on the outside.
I had in my head all the time the battens to form the cavity are 38mm deep, but i have drawn all the drawings with them 25mm deep,... the question is, is a 25mm deep ventilated cavity ok behind the render carrier board, or does it have to be 38mm ?
Thanks
J
