Roofers Choice Blue Factory Graded Batten is graded twice. A pre-grade at the sawmill and a final grading at the planing mill.
This ensures a high quality fully graded batten that meets all aspects of BS5534 : 2014 and eliminates the need for grading on site. This is now a requirement for all NHBC homes.
