We're about to start battening, renderboarding and rendering our timber frame... the renderer has been pushing the structural engineer on whether or not we're required to incorporate compression joints into our huge swaths of render, and, having been somewhat vague about the issue, the engineer now advised compression/movement joints ought to go in.
I've not found much online, but what I've come across is lines that run down or across the render which would tarnish the design of the house. Has anyone had to incorporate these into their build? Would you share pictures? and does anyone know what the guidance is on these? And whether they're necessary?
