Fixing Battens to Timber
Fasten the batten to every truss or rafter with a 12 x 40mm timber fixing screw (minimum fixing size) through each flange.
Fixing Battens to Steel
Fasten the batten to every truss or rafter with a M5.5 x 40mm batten zip (minimum fixing size) through each flange.
Fixing to Roof Sheets
Fasten the roof sheets to the batten as per the roofing specifications.
Fixing to the Ridge
Fix through the ridge capping into the roof batten using the appropriate screws.
To minimise cutting, lay the battens in one direction starting from one end of the roof. The overlap must be supported over a truss or rafter. The minimum overlap is 100mm.
Note: If additional fall protection is required on steel sheet roofs, Ceiling Battens may be fixed intermittently between Roofing Battens giving a batten spacing no greater than 600mm. Roofing Battens are suitable for non-cyclonic conditions up to and including W41 (N3).
