RIDGE STRUCTURE
Before the last top eaves course batten is fixed, fix a 50mm x 50mm bedded batten above the rafters using rafter straps
(non-supplied).
Fix the apex batten to the rafters as shown above Then fix the top batten course, 35mm down from the rafter apex
Ensure that there is a gap of at least
25mm to ensure good ventilation
Note that the rafter straps are usually
supplied flat and need to be bent to shape.
35mm
Use the top batten as a cutting edge to
trim off any excess Envirolay to ensure
that the ridge ventilation path is clear
