Lengths and fixing requirements

JB Red is supplied in lengths generally 3.0m and longer (usually 3.6m and longer). A batten should be a minimum of 1.2m long and span at least 3 rafters. 

Not more than one in four battens should be joined over one truss for gauges over 200mm below 200mm there can be 3 consecutive joins in any twelve battens. The best way to meet this is to buy a spread of lengths so joints can be staggered. 


Once delivered, store battens and counter battens on sufficient bearers to prevent sagging or twisting. They should also be protected from water saturation whilst lying horizontally.
