Timber Frame RENDER TO TIMBER FRAME
It is not essential but NHBC recommended a ventilated cavity behind any cladding system applied to timber frame construction. Traditional methods using Expanded Metal Lath (EML) with a sand and cement render finish saw a mix of three materials (timber / metal / masonry) which expand and contract differently causing the render to crack. So a Render and Board system becomes a great solution.
