Grading

All JB Red roofing battens are supplied graded to meet the performance requirements of BS 5534. Occasionally some end splits may develop after grading. These should be trimmed off at the time of fixing, as should any splits greater than 150mm that occur due to nailing. A quick visual check is always recommended to assess for any handling damage and obvious error. 

 

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. 

Storage 

All JB Red is stored undercover. 

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.
