Vented Soft Edge

Typical soft edge is either soft aluminium or perforated aluminium a with PIB rubber backer. The latter is more common.  The PIB rubber, when dressed down on a hot day, can adhere to the roofing surface and prevent the escape of air at the apex.  By removing all or most of the PIB backing this is avoided, and the perforations in the aluminium become an effective pathway for trickle ventilation, while still being an effective baffle against wind-blown moisture.  This product is marketed as vented soft edge and is available from all suppliers.
